Review of business laptop Digma Pro Magnus M

06.01.2024 12:59

The Digma Pro trademark belongs to the Merlion company, known for its activities in the field of electronics distribution. The company is known in the Russian market for a wide range of peripheral devices, mobile gadgets such as keyboards, action cameras, smartphones and tablets. About a year ago, the company expanded its range by introducing portable business computers under the Digma Pro brand: the line consists of devices with different price segments — Sprint M (more affordable), Fortis M (mid-level) and Magnus M (the most advanced and expensive). First, the first two lines were reviewed, and now the older series is next in line.

Detailed data on the technical characteristics of the device are available on the manufacturer’s official website (by selecting the SSD and processor from the drop-down list), as well as in the table below.

On the official website of the manufacturer Digma Pro Magnus M, three variants of this model are presented, differing in the main characteristics of the processor: AMD Ryzen 5 5600U, AMD Ryzen 7 5800H and AMD Ryzen 9 5900HX. Unlike the simpler Sprint M and Fortis M models, the Magnus M has an M.2 slot for installing an SSD drive with a PCIe Gen3 ×4 interface instead of SATA600, as well as a wireless adapter that supports the 802.11ax standard instead of 802.11ac.

Let's start exploring the Digma Pro Magnus M laptop, starting with an analysis of the packaging's appearance.

The outer packaging is made from recycled materials and is undecorated, containing only informational labels for shipping and storage. The packaging is not equipped with an insertable plastic handle for easy carrying.

But inside the first, outer box, a second, decorative one is found, demonstrating exactly the opposite approach: a gray box with a colorful print, rolled over the image with a glossy printing varnish and polymer lamination.

In addition to the laptop itself, the package includes a power adapter from a household AC network, a user manual and a warranty card.

Appearance and ergonomics

Digma Pro Magnus M is housed in a black metal case (another advantageous difference from the more affordable Digma Pro models). The design is minimalistic.

The laptop has a 16.1-inch screen, which makes it stand out among similar class devices that typically feature 15.6-inch displays. The screen dimensions are 371x247 mm (width and height), and the body thickness at the front is 20 mm (excluding supports). The weight of the device is 1.8 kg.

The laptop's hinges are quite large and only noticeable when opening the device. The maximum opening angle of the lid is 150°. When closed, the lid is held in place by hinges, a closer, and two magnets located under the keyboard bezel at the front edge of the device. The force required for opening was selected optimally: the laptop can be opened with one hand, and the base does not rise on the table or move.

The bottom has a characteristic surface texture; the AMD logo, rather modest-sized air intake grilles, a massive rear support, two thin front ones, as well as compartment covers for access to the RAM module and drives in the M.2 slots attract attention.

In the middle there is a compartment for access to the RAM module with a cover equipped with slots to ensure the removal of heated air.

On the left side of the case (on the right in the photo) there is a second compartment that allows you to replace drives in the M.2 slots without removing the bottom of the laptop.

On the rear panel there are two grilles, right and left, through which heated air is removed from the internal volume.

The left side panel houses a coaxial connector for connecting a power adapter, an HDMI video output, two USB Type-A ports and one USB Type-C port, a headphone audio output and a mechanical switch for the webcam and microphones.

The latter is equipped with its own LED indicator, which lights up red when the devices are turned off...

...and goes out when they are activated.

There is a noticeable protrusion of the lid on the front, with which you can pry it with your fingers to open the laptop.

On the right is a USB Type-A port, an SD card reader slot, an RJ-45 socket with a hinged cover for an Ethernet cable, and a Kensington lock hole.

The screen frame is 8 mm wide at the top, 6 mm on the right and left, and 30 mm at the bottom. It rises above the display surface by 1.5 mm. The screen is semi-matte, measuring 16.1 inches diagonally, and is represented by an IPS matrix.

A miniature webcam with two microphones and an activity indicator is built into the top of the frame.

The laptop has a membrane-type keyboard, which in its layout and functionality is slightly inferior to a standard desktop one. The alphanumeric and character buttons measure 16x16mm, with 18mm between centers and 2mm between edges. The gap is quite large (95 mm). The width of the right Shift is 45 mm, the left Shift is 38 mm, Backspace is 32 mm, Caps Lock is 26 mm, Enter is 36 mm. The presence of a number pad with an almost complete set of keys, but their width is reduced compared to the main buttons. Vertical arrows and function keys F1-F12 are reduced by half in height to 16x8 mm.

The keyboard supports independent keystroke processing (n-key rollover), which allows the system to respond to simultaneous pressing of any number of buttons.

The key travel is about 1.6 mm, clearly perceptible tactilely. Pressing the edges of the buttons works reliably.

The power switch button is moved outside the keyboard area. It is the same type as the front panel, has the shape of a regular circle, not a rectangle

The key is equipped with a ring-shaped indicator and is installed below the panel surface, which prevents accidental pressing. Its surface functions as a fingerprint scanner, allowing the user to be identified when turning on the laptop without the need to enter an additional password.

The touchpad is noticeably shifted to the left of the center of the front panel. It does not have physically dedicated buttons, but pressing its surface is accompanied by noticeable clicks and corresponding feedback. The clickpad is not very large, but comfortable. However, only the closest ⅔ of its surface area to the user accurately responds to clicks.

A standard Phillips screwdriver is required to remove the bottom cover. It is necessary to unscrew 10 screws along the perimeter of the bottom, as well as two screws securing the covers of the drive bays and the SO-DIMM module.

After dismantling the bottom panel, a view of the inside of the laptop opens.

It is possible to replace the single RAM module with a larger one (up to 32 GB). You can also replace the system NVMe drive and install an additional SSD in the second free M.2 slot. The battery is attached to the case with screws and is connected to its own connector, which makes it easy and quick to remove and install.

The quality of the factory assembly is at a high level. Soldering and installation of components are done carefully. However, the presence of loose or taped wires is a cause for concern, as this is a common feature of portable devices made in China.

The Netac system drive with a capacity of 512 GB is installed in the M.2 slot and has a PCIe Gen3 ×4 interface, and the second (free) M.2 slot is designed to use an SSD with a much slower SATA600 interface.

Digma Pro Magnus M has a Mediatek MT7921K wireless adapter supporting the 802.11ax standard (Wi-Fi 6E class). It has two antennas that work simultaneously to receive and transmit in 2x2 MU-MIMO multiple multi-user connections.

Screen

The laptop uses a 16.1-inch IPS matrix with a resolution of 2560x1440 pixels. The outer surface of the matrix is black, hard and semi-matte (with pronounced specularity). There are no anti-reflective coatings or air gap on the matrix. When operating on mains or battery power, without automatic adjustment based on the light sensor, the maximum brightness is 335 cd/m² (measured in the center of the screen on a white background). This indicator allows you to comfortably work or play outside on a bright sunny day, while being in the shade. The following criteria are used to evaluate screen readability outdoors, based on actual screen tests.

Maximum brightness, cd/m²ConditionsReadability Score
Matte, semi-matte and glossy screens without anti-glare coating
150Direct sunlight (more than 20,000 lux)unreadable
Light shadow (approx. 10,000 lux)we can barely read
Light shade and sparse clouds (no more than 7500 lux)work is uncomfortable
300Direct sunlight (more than 20,000 lux)we can barely read
Light shadow (approx. 10,000 lux)work is uncomfortable
Light shade and sparse clouds (no more than 7500 lux)work comfortably
450Direct sunlight (more than 20,000 lux)work is uncomfortable
Light shadow (approx. 10,000 lux)work comfortably
Light shade and sparse clouds (no more than 7500 lux)work comfortably

The criteria used to evaluate screen readability may be revised as additional data accumulates. It is important to note that improved readability is possible due to the potential trans-reflective properties of the matrix, where some of the light is reflected from the substrate, allowing the image to be seen even when the backlight is turned off. Some glossy matrices can also be rotated to reflect something fairly dark and uniform (like the sky on a clear day) to improve readability, while matte mattes are better shielded from ambient light to improve readability.

Let's get back to testing the screen of this laptop. With the brightness setting at 0%, the screen brightness is 43 cd/m². In complete darkness, the screen brightness can be reduced to a comfortable level.

At any brightness level, there is no significant backlight modulation, which eliminates screen flickering (no PWM). To confirm this, we present graphs of brightness (on the vertical axis) versus time (on the horizontal axis) for various brightness settings.

This laptop uses an IPS matrix. Microphotographs show a typical IPS subpixel structure (black dots are dust on the camera matrix):

Focusing on the screen surface revealed randomly located surface microdefects responsible for the matte properties:

The grain of these defects is several times smaller than the size of the subpixels (the scale of these two photographs is approximately the same), so focusing on microdefects and the “jumping” of focus across subpixels when changing the viewing angle are weakly expressed, because of this there is no “crystalline” effect.

We measured brightness at 25 points on the screen, located in increments of 1/6 of the screen width and height (screen borders not included). Contrast was calculated as the ratio of the brightness of the fields at the measured points:

ParameterAverageDeviation from the average
min., %max., %
Black field brightness0.28 cd/m²−5.012
White field brightness330 cd/m²−5.13.3
Contrast1200:1−154.4

Moving away from the edges of the screen, white uniformity is very good, but black uniformity, and therefore contrast, is a little lacking. The contrast by modern standards for this type of matrix is above average. It is visually noticeable that the black field closer to the edges is slightly lighter. However, this unevenness in black brightness is only visible in very dark scenes and near-total darkness, which is not a significant drawback.

The screen cover is not too rigid and can be slightly deformed under slight pressure, which significantly affects the uniformity of the black field.

The screen has good viewing angles without significant color changes even at large viewing angles from perpendicular to the screen, without inversion of shades. However, when deviated diagonally, the black field is greatly lightened and acquires a red-violet tint.

The response time when changing black-white-black is 10 ms (5 ms on + 5 ms off), the transition time between different shades of gray in total (from one shade to another and back) averages 13 ms. Although the matrix is fast, there is no explicit mention of overclocking.

Let's check whether this matrix speed is sufficient to display images at a frequency of 165 Hz. Let's imagine the dependence of brightness on time when alternating white and black frames at a frame rate of 165 Hz.

From the presented data it can be seen that at a frame rate of 165 Hz, the maximum brightness of a white frame exceeds 90% of the white level, and the minimum brightness of a black frame falls below 10% of the white level. The total amplitude is more than 80% of the brightness of white. This formal criterion shows that the matrix speed is sufficient to fully output images at a frame rate of 165 Hz.

To give a more clear idea of what such a matrix speed means in practice and what artifacts can arise as a result of overclocking, we will provide a series of pictures taken while the camera was moving. These images show how an object on a screen is perceived by the human eye as it moves. For this, the recommended settings were used: motion speed 960 pixels/s for 60 Hz and 990 pixels/s for 165 Hz frame rate, shutter speed 1/15 s.

Let's imagine how this would manifest itself in the case of a matrix with instantaneous pixel switching. At 60 Hz frame rate, an object moving at 960 pixels per second is blurred by 16 pixels, and at 165 Hz (990 pixels per second), it is blurred by 6 pixels. This blur occurs because the focus of view moves at a specified speed while the subject remains static on the screen for 1/60 or 1/165 of a second. To demonstrate this, we can simulate a blur of 16 and 6 pixels:

When comparing the real image with the ideal matrix representation, it is noticeable that the clarity of the real image is significantly lower.

We measured the total delay from switching the video buffer page to the start of displaying the image on the screen. Note that this delay depends on the characteristics of the Windows operating system and video card, and not just on the characteristics of the display. At 165Hz refresh rate the latency is 6ms. This is a very small delay that is almost unnoticeable during everyday use of the computer, even in very dynamic games, and it does not reduce overall performance.

Screen settings provide the ability to select two refresh rates: 60 Hz and 165 Hz. At least at the native screen resolution, output is 8 bits per color. From the information on the video adapter's control panel it follows that the screen supports AMD FreeSync technology in the range from 60 to 165 Hz.

In addition, we measured brightness for 256 shades of gray (0, 0, 0 to 255, 255, 255). Below is a graph showing the increase in brightness between adjacent halftones (not absolute values).

The increase in brightness on the gray scale is mostly uniform, and each subsequent shade is brighter than the previous one. In the darkest area, all shades are distinguished hardware-wise and visually:

The approximation of the resulting gamma curve gave a value of 2.09, which is slightly lower than the standard value of 2.2, so the picture is slightly brightened. In this case, the real gamma curve slightly deviates from the approximating power function:

Color gamut is close to sRGB:

Therefore, visually, the colors of images oriented to output in the sRGB space on this screen have a natural saturation. Below is the spectrum for the white field (white line), superimposed on the spectra of the red, green and blue fields (lines of the corresponding colors):

Apparently, this screen uses blue emitter LEDs in combination with green and red phosphors (usually a blue emitter and a yellow phosphor). This provides good separation of color components. In addition, it is possible that quantum dots are used in the red phosphor. However, special filters cross-mix the components, which limits coverage to sRGB.

The screen's grayscale balance is acceptable, as the color temperature is fairly close to the standard 6500K and the spectral blackbody deviation (ΔE) is either below 10 or just above. For a consumer device this is considered acceptable. In addition, color temperature and ΔE change little from one shade to another, which has a beneficial effect on the visual assessment of color balance. It is important to note that the darkest areas of the gray scale may not have a significant color balance value, since at low brightness the error in color measurements can be significant.

In terms of maximum brightness, Digma Pro Magnus M takes second place in our correspondence competition. This indicator for the hero of the review cannot be considered truly high, but it is still quite acceptable.

The color space coverage of the rivals is more or less the same (and approximately corresponds to sRGB).

Digma Pro Magnus M
Tecno Megabook S1
MSI Prestige 14 Evo

However, of these, we are more impressed by Digma Pro Magnus M, since in two axes it is slightly superior to the standard, which means it provides higher color saturation.

Battery operation

The total capacity of the three-cell battery is 70 Wh. In order to get an idea of ​​how this parameter relates to battery life in practice. Screen brightness in testing is set to 100 cd/m² — in our case, this corresponds to approximately 27% in Windows 11 installations. This standardizes backlight power consumption to a certain extent, and laptops with dim screens do not benefit.

In addition to the usual battery life testing procedure, let's compare the results obtained with similar data from two other business laptops of a comparable price category that we have tested previously:

  • Tecno Megabook S1 with 70 Wh battery 
  • MSI Prestige 14 Evo with 54 Wh battery 

When used on battery power to work with text or browse the Internet without performing heavy scripts (key backlighting is set to minimum), Digma Pro Magnus M provides the user with a runtime of 8 hours 47 minutes on a single full charge. This allows you to fully use the laptop during the working day with a possible lunch break, without worrying about recharging. When watching a video on a laptop screen (with the key backlight turned off), the battery life is 6 hours 20 minutes. This almost completely covers the duration of a continuous flight, for example, from Moscow to Irkutsk.

Competitors in this competition show a significant advantage in battery life over the model in question, which reflects the difference in energy efficiency between AMD and Intel laptop processors.

The power supply is small (368 g), but still significantly larger than a similar adapter for a smartphone and tablet.

To connect it, use the coaxial connector on the left on the side panel near the lid hinge. The LED indicator located next to the connector glows orange until the battery capacity is 100% full, then switches to white.

50% of the battery capacity is accumulated in 1 hour 13 minutes, charging from 0 to 80% requires 2 hours, and from 0 to 100% the process requires 2 hours 45 minutes. Here's how it compares to the competitors mentioned.

The Digma Pro Magnus M takes less time to charge its battery than its competitors in our impromptu correspondence competition.

Wi-Fi

Digma Pro Magnus M is equipped with a Mediatek MT7921K wireless adapter that supports the 802.11ax standard (Wi-Fi 6E), has two antennas and is capable of simultaneously receiving and transmitting (2T2X) in the MU-MIMO multiple multi-user connections mode. To verify that the network connection speeds meet the needs of the gaming machine, we will conduct tests in a network environment.

Connection to the Internet is carried out through the MGTS/MTS provider via a gigabit passive optical network (GPON), the RV6699 subscriber terminal performs the functions of an optoelectronic converter, modem, telephone switch and primary WAN router. Currently, due to technical limitations of the provider, only speeds up to one gigabit are available, which does not allow the use of an external network segment supporting 2.5GbE.

A secondary device in the network, but having a major role in organizing the network infrastructure, is the TP-Link Archer AX72 dual-band router with Wi-Fi 6 AX5400 standard.

Let's move on to testing the operation of Digma Pro Magnus M in a wireless network using the iperf utility and compare the results obtained by the Realtek 8821CE adapter from the hero of the review with two other client devices tested earlier:

  • Intel AX211 on Tecno Megabook S1 
  • Intel AX210 on Lenovo Thinkbook 14s 

The laptops were connected via Wi-Fi (5 GHz band) to a TP-Link Archer AX72 wireless router in three rooms:

  1. At a distance of 4 m from the router in its line of sight (without obstacles)
  2. At a distance of 4 m from the router with an obstacle in the form of one brick wall
  3. At a distance of 6 m from the router with obstacles in the form of two brick walls

The iperf “server” application was launched on the clients. The measuring station was a reference desktop connected to the same router via a UTP Cat5E cable, and the iperf “client” application was launched on it.

Based on the results of testing connection speeds, the Mediatek MT7921K adapter used in the Digma Pro Magnus M laptop shows some lag behind the Intel AX210 and Intel AX211 devices used by competitors. This is especially noticeable when using eight data streams, at large distances from the router and in conditions that are not optimal for radio signal propagation. However, it is important to note that the user has the right to replace the supplied adapter with a more advanced model in the future, if necessary.

Working under load

The cooling system of Digma Pro Magnus M differs significantly from conventional business laptops that do not use discrete graphics. Typically, such laptops have only one fan and radiator installed to cool the components. In contrast, the model under discussion has a more powerful system: two fans, two heat pipes and two radiators. The influx of cold air is carried out through the holes in the bottom in two streams, and the heated air is discharged through two grilles located on the right and left on the rear panel of the laptop.

In the next series of tests, we will check how adequately the cooling works in extreme conditions using the powerMax utility, and we will take the necessary readings in the form of screenshots of the HWinfo utility under maximum load on the central processor, on the video accelerator, and on both computers simultaneously. Digma Pro Magnus M does not have a proprietary utility for selecting a work preset (scenario, profile). There are no options in the BIOS settings for overclocking the processor, RAM, etc. To evaluate how system parameters change, we provide a table containing data on consumption, temperature and clock speed for the central processor.

Load scenarioCPU frequencies, GHzCPU temperature, °CCPU consumption, W
Inaction 423
Maximum CPU load3.08751
Maximum load on CPU+GPU1.57646

When there is no load, the CPU draws only 3 W of power, and its temperature barely reaches 42 ° C with a silent fan.

Maximum CPU load

Maximum CPU load

At maximum load on the main computer there is no initial acceleration; the clock frequency is 3 GHz (nameplate maximums are 3.3 GHz and 4.6 GHz in turbo mode), consumption is 51 W (TDP 35-54 W). CPU heating does not exceed 87°C.

Maximum load on the central processor and video accelerator

Maximum load on the central processor and video accelerator

At maximum load on both processors, initial overclocking is not activated. However, due to the high consumption of the GPU, the clock speed and power of the CPU are limited significantly (1.5 GHz and 46 W). These indicators remain at restrictive levels throughout the testing period.

Based on the tests carried out, it can be concluded that the automatic control is configured in such a way that the system fails to activate the initial acceleration or use the remaining power reserve. At the same time, the cooling system does its job well, preventing overheating of the central processor and an unwanted decrease in its performance.

Below are thermal images taken after the laptop was running for a long time with maximum processor load:

Above
From below
power unit

Under maximum load, it is comfortable to work with the keyboard, since the areas under the wrists practically do not heat up. Holding a laptop on your lap is unpleasant because your knees are partially in contact with high-heat areas. Your knees can also block the intake vents (which does not happen when the laptop is placed on a flat, hard surface), which can cause the laptop to overheat. Despite all possible safety measures, overheating can still lead to unpleasant consequences. The power supply gets very hot, so when working for a long time with high performance, you must make sure that it is not covered with something.

Noise level

We measure the noise level in a special soundproof chamber that is partially muffled. The microphone of the sound level meter is installed in such a way that its position simulates the usual position of the user's head: the laptop screen is tilted back 45 degrees or at the maximum angle if the screen does not tilt back to 45 degrees. The axis of the microphone is directed from the center of the screen, its front edge is at a distance of 50 cm from the screen, and the microphone is directed towards it. The load is created using the powerMax program, the screen brightness is set to maximum. The room temperature is kept at 24 degrees, and the laptop is not specifically cooled, so the ambient temperature may be higher. To estimate real energy consumption, we also provide grid consumption data in some modes. The battery is pre-charged to 100%.

Load scenarioNoise level, dBASubjective assessmentMains consumption, W
Inaction16.1 (background)conditionally silent10
Maximum CPU Load42.4very noisy71 (max 78)

If the laptop is not loaded at all, then its cooling system under the above conditions can operate in passive mode. The nature of the noise, even under high load, is even and does not cause irritation. The spectrogram obtained for the maximum fan speed is quite smooth, and there are no pronounced peaks in the frequency range where sounds can cause particular irritation:

To subjectively assess the noise level, we use the following scale:

Noise level, dBASubjective assessment
Less than 20conditionally silent
20-25very quiet
25-30quiet
30—35clearly audible
35—40noisy
40—45very noisy
45—50loud
Above 50very loud

The visually representable noise level can be assessed as follows:

  • Below 20 dBA: The computer is considered virtually silent.
  • 20–25 dBA: The laptop can be called very quiet.
  • 25–30 dBA: The noise from the cooling system does not stand out much from the background sounds in the office.
  • 30–35 dBA: The noise is clearly audible, but does not exceed the typical operating background.
  • 35–40 dBA: The noise exceeds a comfortable level for long-term operation.
  • 40–45 dBA: The laptop is very noisy and requires the use of background music to mask the noise.
  • 45–50 dBA: The noise level is very uncomfortable.
  • 50 dBA and above: The noise is so loud that the use of headphones is required.

This is a conditional scale and does not take into account the individual preferences of each user and the nature of the sound.

Digma Pro Magnus M is noisier than other participants in our competition, however, its consumption is significantly higher (71 W).

Performance

Digma Pro Magnus M is equipped with the AMD Ryzen 9 5900HX mobile processor with Zen3+ microarchitecture (Cezanne generation), which was announced in 2021. It has eight cores, each of which supports Hyper-Threading (16 threads in total). The base clock frequency is 3.3 GHz, and the maximum in turbo mode is 4.6 GHz. The thermal package is 45 W during stable operation and up to 54 W during overclocking. In tests under load, we saw that the processor took up to 51 W of power, which exceeds the requirements of the thermal package, but the turbo mode was not activated. The clock frequency did not exceed 3 GHz, which is less than the rated maximum.

AMD Ryzen 9 5900HX can work with DDR4 and LPDDR4 RAM. The laptop can install one SO-DIMM module (in the factory configuration — 16 GB DDR4-3200).

Let's compare the results obtained with the data of competitors who have already participated in the comparison earlier. Both competitors have LPDDR memory, which is soldered on motherboards

The hero of the review is equipped with full-fledged DDR4 in the form of a SO-DIMM module (though only one, which does not allow the RAM to operate in dual-channel mode). Let's compare the results of the AIDA64 benchmark

MSI Prestige 14 Evo

Let us present the obtained indicators in the form of diagrams.

The best results are demonstrated by the RAM in the Tecno Megabook S1 laptop, and the most modest results are demonstrated by the DDR4-3200 running in single-channel mode as part of the review hero. Later we will be able to determine to what extent these features affect the performance of Digma Pro Magnus M when tested in real applications.

The Netac S930E 512 GB solid-state drive with a PCI Express 3 × 4 interface acts as a storage for installed programs and user data. In the process of testing using the popular CrystalDiskMark benchmark, we will determine its capabilities and compare them with the performance of drives installed in two other business laptops:

  • Tecno Megabook S1 – 1 TB Foresee FSb0C001T (PCIe Gen 4 ×4)
  • MSI Prestige 14 Evo – 512 GB Micron 2450 (PCIe Gen 4 ×4)

The test results look more clear (especially in terms of comparison) in the diagrams.

The system drive in the laptop in question shows results that lag behind similar devices included in the comparison group.

Although our laptop's processor is not the newest or top-end in the laptop CPU category in terms of speed, its performance remains at a fairly high level. To compare performance, we will use this processor compared to business machines equipped with similar processors. We will use the 6-core Intel Core i5-9600K as a reference system for traditional comparison.

The Digma Pro Magnus M delivers impressive performance, outperforming the reference desktop PC with Intel Core i5-9600K processor in all categories. In three out of seven tests (video conversion, rendering, text recognition), the review laptop is ahead of both competitors. The results obtained make it possible to significantly expand the scope of use of the device beyond simple office tasks and include media content processing (although, of course, more powerful systems are preferable for this purpose). The integrated result of the drive slightly worsens the overall picture, but we have already noted this when analyzing the test results using CrystalDiskMark. For a clearer comparison with competitors, let’s present the scores obtained in diagrams.

In certain nominations, the hero of the review shows himself very well. However, system storage performance can be critical...

..and this is where Digma Pro Magnus M turns out to be weaker. As a result, the hero of the review loses in terms of integral performance results. True, its lag cannot be considered critical, and the laptop is quite suitable for performing complex tasks that go far beyond the scope of purely office use of a mobile PC.

Game testing

The AMD Ryzen 5 5900HX processor includes integrated AMD Radeon Graphics. Although it can't compete with discrete graphics cards and isn't the best choice for today's fast-paced games, we tested its capabilities in four different games. During testing, we used standard graphics settings with medium settings and texture smoothing disabled (anti-aliasing disabled). Below is a table of average and minimum frames per second (fps) values obtained in the corresponding built-in benchmarks.

With a resolution of 2560x1440, there is no need to talk about playability on the Digma Pro Magnus M: even in World of Tanks, freezes and image twitching due to frame drops are noticeable. But at 1920x1080 the “tanks” are quite playable. In other cases, we cannot say anything comforting. Digma Pro Magnus M is still intended for business use and will not cope with modern dynamic games.

Conclusion

The business-oriented Digma Pro Magnus M laptop is an improved version of the portable PC with a focus on hardware capabilities and speed. This product is marketed by the distribution company Merlion and has a minimalistic yet elegant design that is attractive to consumers. Key specifications include an anodized all-metal body, a 16.1-inch matte IPS display with a resolution of 2560×1440 and a refresh rate of 165Hz. The screen has high brightness, wide sRGB color gamut and fast response time.

The keyboard with numeric keypad provides convenience both when working with text and when entering numeric data in spreadsheets. Hardware components were selected taking into account various factors, not always focusing solely on cost. The laptop is loaded with features for business use, including a webcam and hardware-disabled microphones, a fingerprint scanner for user authentication, and built-in Ethernet and Wi-Fi 6E adapters.

However, some characteristics do not meet expectations. For example, the wireless adapter turned out to be less powerful compared to its Intel AX210 counterpart, and the cable connection only supports gigabit speeds instead of 2.5 Gbps.

The AMD Ryzen 9 5900HX central processor, although it has high performance, does not always activate even the standard turbo mode in tests with maximum load due to limitations in the BIOS Setup options. DDR4 RAM in the form of a single 16 GB module is inferior in speed characteristics to competitors using a dual-channel configuration.

The system drive is an SSD from Netac, which, according to test results, is not the fastest. The ability to install a second drive is provided, but the connection interface is limited to SATA, not PCIe.

The set of ports includes various options, including a separate video output and support for video output via USB Type-C. However, in the absence of USB 4 and/or Thunderbolt ports, some options are limited.

Tests in real applications show that the laptop has good performance, but is inferior to some competitors with lower-level processors, which is due to both the RAM operating in single-channel mode and the not-fastest SSD.
