High quality handheld PC game device for in-depth experience of GPD Win4 handheld

In recent years, the popularity of Windows handheld computers has gradually increased, becoming the preferred device for many PC game enthusiasts. The reason is that Windows handheld computers can enable PC game players to play their favorite games anytime and anywhere. At the same time, because they are equipped with an open system such as Windows, they can not only run PC games, which is undoubtedly a great temptation for game players.

GPD is a well-known brand in the field of Windows handheld computers. It has been working hard in the field of portable PC devices for many years. From handheld computers to Windows handheld computers, it can be said that it has really found a way of development. The most popular handheld device under GPD in the near future is GPD Win4. This Windows handheld device equipped with AMD's Reelung 7000 platform has attracted a lot of attention since it was announced. Its familiar appearance design, slide keyboard design, and excellent performance show really make friends who like this kind of device want to stop.

Recently, the author also got this handheld device. As an old player who has traveled for more than 30 years, the author also likes this machine very much.

The overall design of GPD Win4 is very similar to that of PSP, but in fact, the details are very different. The control part of this machine uses two ALPS rockers, which are more damped and smoother than Hall rockers. The rocker is designed in an asymmetric position, which makes the control feel very good. The cross key on the left side of the machine is also very comfortable to adjust, with distinct elastic feedback and clear and neat return force, but the pressure gram is controlled relatively lightly, so it is very convenient to press, even if the "C-hand" is used for operation, there is no pressure.

The touch of the four buttons on the right side is the same as that of the cross button on the left side. However, when I first got the machine, I was afraid that it would be inconvenient to press the buttons when I played games. However, I found that I could get used to the design of these small buttons with a little adaptation, because the touch of the buttons is not soft, but crisp press feedback, Therefore, the control is not inconveniently imagined.

What is worth mentioning on the right side is actually the small square button under the rocker, which is similar to the pointer on the ThinkPad notebook, and is mainly used as a mouse. It is very convenient to experience on the whole.

The left and right grip areas on the back of this machine are equipped with back keys. However, due to the limited space, the back key feel can only be sacrificed. This aspect is completely understandable. However, for Quickcom players, the lack of back key feel is really not convenient.

GPD Win4 interface is basically a common configuration of Windows handheld computers. A USB Type-C is designed in the middle of the bottom, and there is an SD card slot below, which is convenient for expansion of storage space.

The top of the machine body is equipped with a 3.5mm headset jack and a dedicated Oculink interface, which can enhance the game performance by connecting a video card device with a dedicated cable. On the right side is a fully functional USB4, which supports charging, graphics card expansion, and data transmission. Function keys include volume adjustment key and power key.

In addition, the overall feel of the L/R key on the top of this machine is also quite good, and it is also equipped with backlight. However, the backlight effect is still a gap compared with some major lamp manufacturers.

The most amazing thing about GPD Win4 is the slide type keyboard design. The screen can be gently pushed up to see the lower keyboard, which is convenient for input when moving.

The endurance of GPD Win4 is not much different from that of other Windows handheld computers. Some games with low hardware performance requirements can be played for about 2-3 hours. Large 3A games generally have a endurance of about 1.5 hours.

In addition, because GPD Win4 itself can be regarded as a notebook computer, it can be directly connected to an external display screen through USB4, and the external display screen does not need to be connected to a separate power supply, so it can easily realize a large screen game experience.

Next, let's take a look at the performance of this machine.

GPD Win4 has a variety of configurations to choose from. The top configuration model of AMD Reelong 7 7840U processor, 64GB memory, and 2TB solid state disk is obtained by the author. This configuration does not need any expansion upgrade.

The AMD Reelong 7 7840U processor is designed with 8 cores and 16 threads. The base frequency is 3.3GHz, the acceleration frequency is 5.1GHz, and the TDP is between 15W and 30W. How about its performance?

Under the CPU-Z test standard, we can intuitively understand the single core and multi-core performance of this processor. The single core score is 660 points, and the multi-core score is 5056.8 points. This performance is already quite powerful on handheld devices.

Under the CINEBENCH R23 test standard, this processor has a multi-core score of 11474pts and a single core score of 1780pts, showing excellent performance.

The Rayon 7 7840U processor comes with Radeon 780M integrated display, 12 sets of CU, GPU frequency up to 2.7GHz, and 512MB GDDR5 video memory.

In the 3D Mark test, the graphics card scored 2693 points in Time Spy mode and 7761 points in Fire Strike mode.

How does it perform in the actual game? Let's take a look at the game test.

First Steam Online game ranks first all the year round and is the world's hottest e-sports game《 CS : GO, under the default 1920 × 1080 resolution and full height image quality, the average frame number has reached 161.06fps. As a reference, GPD Win4 has no problem running some online games and video games with low hardware requirements.

Let's look at Cyberpunk: 2077, a hardware killer. We tested it separately Steam Deck Mode and low quality mode, the resolution is also 1080P. It can be seen that in Steam Deck mode, the average frame number of the game is 33.91fps, which can run smoothly; In the low image quality mode, it can reach 45.41fps, and the experience is better.

In the test of Tomb Raider: Shadow, we also distinguish between high and low image quality. The resolution is 1080P, and the average measured high image quality is 39fps, while the low image quality can reach 49fps.

Total War: The Three Kingdoms is a game with high requirements for processor performance. During the test, low image quality and 1080P resolution are enabled. The size of the army is the default. The measured average frame number is 70.9fps. The experience is quite smooth.

In terms of games, we will not test the majority of independent games, such as the recently popular Diver Dave《 Empty Knight 》Games like this can run stably at 60fps. So devices like GPD Win4 are more suitable for playing independent games.

In addition, the evaluation model is equipped with 64GB DDR5 memory. According to the actual measurement of AIDA 64, its memory reading speed reaches 50316MB/s, writing speed 93522MB/s, copy speed 68960MB/s, and latency 126.5ns.

In terms of hard disk, this product is equipped with a 2TB PCIe 4.0 solid state disk with a reading speed of 6825.74MB/s and a writing speed of 90.6516MB/s. It is absolutely enough to play games. Even in a laptop, the reading and writing performance of this hard disk is very strong.

In addition, GPD G1 graphics card dock newly released by GPD can be connected to GPD Win4 through USB4 and Oculank at the same time. This graphics card dock is small in size, and its overall size is similar to that of GPD WIN 4 handheld computer. Its length, width and height are 225 × 111 × 29.8mm respectively. Compared with traditional graphics card dock, it has excellent portability. It is also the smallest mobile graphics card dock in the world at present. It has a built-in AMD Radeon RX 7600M XT GPU. Now let's see how GPD Win4 performs after connecting to the docking station?

First of all, from the basic parameters, Radeon RX 7600M XT adopts AMD's latest RDNA 3 architecture design, with 32 computing units, 64 raster units, 4096 stream processors, game frequency: 2300 MHz, acceleration frequency: 2615 MHz, and power consumption of up to 120W. At the same time, it supports InfinityCache, totaling 32MB. The video memory is 8GB GDDR6, and the video memory bit width is 128bit.

The biggest highlight of Radeon RX 7600M XT is the RDNA 3 architecture. We can see how much improvement it has brought about by simply comparing several sets of data. For example, the previous generation Radeon RX 6650M XT is basically the same in terms of core parameters such as the number of computing units, raster units, and stream processors, but their computing performance has improved a lot. In terms of semi precision calculation, RX 6650M XT is 19.94TFLOPs, while RX 7600M XT is 42.8TFLOPs, more than doubling; In terms of single precision computing, RX 6650M XT is 9.97TFLOPs, RX 7600M XT is 21.4TFLOPs, which has also doubled. This is the advantage of the new RDNA 3 architecture.

Next through 3DMark Check out the theoretical performance of the Radeon RX 7600M XT in the GPD G1 graphics card dock. To clarify, the performance here is the performance of the internal screen, and the performance will be higher if the external screen is connected.

The video card score is 7176 in Time Spy (DX12, 2K) mode of 3DMARK, and 19379 in FireStrike mode.

All friends who know about computers know that although the performance loss of the external graphics card will be reduced to the greatest extent after the USB4 connection, after all, it is not directly connected to the PCIe slot, so there will still be some loss. However, there is no problem in using the lost performance for the handheld computer.

Compared with the Radeon 780M integrated display of GPD WIN 4 handheld, Radeon RX 7600M XT improves the graphics performance of GPD WIN 4 handheld by 166% in Time Spy DX12 and FireStrike DX11 The graphics performance has improved by 150%, which means that after connecting the GPD G1 graphics card dock, the GPD WIN 4 handheld computer can run large 3A games more smoothly.

After understanding the theoretical results, let's see the actual game performance. Here we choose four 3A games, Tomb Raider: Shadow, Total War: The Three Kingdoms, Eldon Fahuan and Cyberpunk 2077, to test the effect of external video cards. The bottleneck of online games is basically not the video card, so we don't compare them.

The first is Tomb Raider: Shadow, which requires a little more hardware. The image quality is set to 1920 × 1080, DX12 is enabled, and the image quality is adjusted to the highest. Run when GPD G1 is connected externally Benchmark The average fluency is 71 fps, which brings a very good experience.

The second test game is Total War: The Three Kingdoms. The pressure of this game on hardware is significantly higher than that of the previous game. The picture quality is set to 1920 × 1080, the picture quality is set to the second "higher" picture quality gear, and the troop size is the default. Running Benchmark got an average score of 63.9 fps, which was good.

The third test game is Eldon Fa Huan. The resolution during the test is 1920 × 1080, and the image quality is adjusted to the highest. In addition, we compared the number of game frames when GPD G1 is connected and not connected in the same scene, as follows:

It can be seen that when GPD G1 is not connected, the frame number of the picture is only 37fps, and after the connection, the smoothness of the game lock can be reached at 60fps. For such a difficult action game as Eldon's Circle, it is unnecessary for the author to say how important the fluency of 60fps is.

The last game is Cyberpunk 2077, which is very stressful for hardware. The picture quality is set to 1920 × 1080. The picture quality is preset to select the handheld mode picture quality. The light tracing is not started. Running Benchmark finally gets an average picture fluency performance of 60.36 fps.

It can be seen that after the external GPD G1 is connected, the fluency of the 3A game of GPD Win4 is greatly improved, and the PC level game experience is realized.

·Evaluation summary

On the whole, GPD Win4 is really a very good product in the Windows handheld computer camp, and the GPD G1 graphics card docking station matched with it is also interesting. Whether you use GPD Win4 handheld computers alone or use them together, you can bring gamers a good experience of handheld PC games.
