GPD WIN 4 2025 Review – Is the HX 370 CPU worth upgrading to?

The GPD WIN 4 2025 came as a bit of a surprise for us in late 2024 as we were hoping to see the GPD WIN 5 announced. Featuring the new AMD HX 370 processor, the Win 4 sees its fourth iteration in this series. Let’s see how this handheld gaming PC compares with the other processors in our GPD WIN 4 2025 review and find out if it is worth upgrading from them.

GPD WIN 4 2025 Overview

Let’s start our GPD WIN 4 2025 review with an overview. The GPD WIN 4 2025 portable gaming PC is physically essentially the same device as the previous Win 4 generations. It measures around 6 x 3.6 x 1.1 inches (22.0 x 9.2 x 2.8 cm) and weighs 598g (1.31 lbs).

The familiar 6” display with up to 1080P resolution, supporting 40Hz and 60Hz, looks as great as ever. The H-IPS display is bright and colourful and apart from very small text in games being tricky to read in some situations, I have no complaints about the screen.

The display slides up to reveal the QWERTY keyboard. It has a white backlight which can be switched off if required. The keyboard keys are quite small, you would not be able to use it like a normal desktop style keyboard, it’s more of a thumb or finger typing usage. It’s useful for brief typing such as emails, discord chat, web browsing etc.

On either side of the handheld we have dual analogue sticks, a D-pad, fingerprint scanner, game buttons and an optical finger mouse. The left side has a micro SD card reader and a switch to change between mouse and controller mode for the controls. The bottom has a USB Type C port.

Along the top there are Left and Right Shoulder and Trigger buttons. In between those are the power button, volume buttons, a USB 4 port and Oculink port for connecting to an eGPU. And last but not least is a 3.5mm headphone port.

The GPD WIN 4 series has been around for a few years now and I have personally spent many hours playing on them all. The controls are spot on for me and are great for both modern dual stick gaming as well as retro gaming with the D-Pad.

While running Cinebench on a loop at full brightness, 28W TDP, we got a battery life of around 57 minutes. Average usage will of course be higher at around 3 to 6 hours depending on demand.

In our fan noise and temperature tests, also while running Cinebench. We got a highest fan noise of 64 dB and 45°C.

System Benchmarks

As always we have some system benchmarks to see the performance with other similar processor mobile gaming PCs for our GPD WIN 4 2025 review. We also have updated benchmark results for the previous generations GPD WIN 4 2022 with 6800U, GPD WIN 4 2023 with 7840U and GPD WIN 4 2024 with 8840U to see the differences in performance with the GPD WIN 4 2025 with HX 370.

PASSMARK

We start the benchmarks with Passmark which gives a general overview of the CPU, GPU, RAM and STORAGE performance.

We get a highest score of 8,229, a 40% increase in performance over the original 6800U model, and a 10% increase over the 8840U generation portable gaming computer.

PCMARK

PCMARK tests the day to day software usage ranging from web browsing, working with office documents and image editing for example.

We get a score of 7,273 for the HX 370 model, around an 18% increase over the original 6800U model, and around a 5% increase over the 8840U model.

Compared with other HX 370 models we see around average scores when compared with the GPD Duo, GPD Pocket 4 and ONEXFLY compact gaming PC.

Cinebench 2024

Cinebench tests the CPU single and multicore performance. We get core scores of 117 and 951 respectively. This is a great increase of 30% and 50% over the 6800U model, and 17 and 24% over the 8840U model. 

Compared with the other HX 370 models we see identical single core scores as expected with the GPD WIN 4 2025, and around average scores for multi-core performance.

Geekbench 6

Geekbench 6 also tests the CPU performance across single and multi-core performance. We see a 40% and 37% increase over the 6800U model and 17% and 10% increase over the 8840U model.

Compared with the other HX 370 handheld gaming computers we see near the highest single core performance, though this drops to the lowest for multicore performance.

3DMARK

With 3DMARK we ran the Time Spy, Night Raid and Fire Strike benchmarks. The 2025 model naturally has the highest scores across the three tests, as high has 36% against the 6800U and 19% against the 8840U.

And compared with the latest HX CPU models we see amongst the highest scores for the GPD WIN 4 2025, with clear first places in two of the three benchmarks, and second place in the third.

Gaming Benchmarks

For the gaming benchmarks in our GPD WIN 4 2025 review we are also testing at 1080P and 720P with a range of TDP settings to compare the performance differences on the Win 4 series as well as with other current generation HX 365 and HX 370 portable gaming PCs such as the ONEXPLAYER ONEXFLY F1 PRO.

Forza Horizon 5

AMD processors have always had great results on Forza and the trend continues with the HX 370. At 1080P resolution, we see 33% increases in performance over the 6800U, and around a 15% increase over the 8840U.

Compared with the ONEXPLAYER ONEXFLY F1 Pro we see the Win 4 has a few extra frames at 1080P and as we go across the TDP’s at 720P we see the F1 Pro catch up and overtake in some benchmarks.

Cyberpunk 2077

At 720P we get an impressive 69 frames per second with the HX 370, around a 20% increase over the 6800U but only around 5% over the 8840U. Not a massive increase here for this game.

Compared with the F1 Pro, the Win 4 nudges ahead by a few frames per second at 1080P and behind a few frames at 720P across the TDP range.

Shadow of the Tomb Raider

We see a roughly 20% increase in performance on the HX 370 over the original 6800U compact gaming PC, and a 14% increase over the 8840U model. There’s larger performance increases than with Cyberpunk which is good to see.

Compared with the F1 Pro we see a few frames higher at 1080P again. At 720P across the TDP range we see it trade first and second place with the F1 Pro.

Benchmark Summary

Overall we see good increases in performance across the generations of processors in our GPD WIN 4 2025 review. If you have the 6800U handheld gaming computer then there’s some great increases in performance with the HX 370 on the GPD WIN 4 2025. Compared with the 7 and 8 series processors we do not see as large an increase in gaming performance, anything from 5% to 15% across the three benchmarks we used, though you may see higher in others.

Compared with the other HX 370 models we see competitive results. At higher resolution and TDPs, the GPD WIN 4 2025 seems to be better performing than the F1 Pro with HX 370. And at lower resolutions and TDP, the F1 Pro does seem to have the performance edge. With some tweaking between CPU and GPU power you can essentially get similar results depending on where you want the performance.

Gaming Performance

We could not make a GPD WIN 4 2025 review without taking a look at some games running at playable settings on the GPD WIN 4 2025. 

On Indiana Jones and the Great Circle we are running at 720P resolution with Medium graphics settings locked to 30 FPS at 28W TDP.

For Nine Sols we are running at 1080P resolution on the High Graphics settings at 5W TDP. With Road 96 we are running at 1080P resolution on the High Graphics settings at 28W TDP. Carrion is a fairly low demanding game which runs at 1080P resolution at only 5W TDP.

The Spyro Reignited Trilogy looks and runs great at 1080P resolution on the Ultra Graphics settings at 28W TDP, could lower the TDP a bit as well.

And Overthrown is running great at 1080P resolution with AMD FSR Balanced at 28W TDP.

Emulation Performance

We know from the 8840U generation and our recent review with the GPD Duo and Pocket 4 with HX 370 that emulation performance is very impressive. We will briefly cover the emulation performance in our GPD WIN 4 2025 review.

You will have no issues running up to say PlayStation 3 era with compatible games on the GPD WIN 4 2025. And for most systems before that, you can increase rendering resolutions, add graphics filters etc for improved visuals.

Going on to discontinued emulators such as Ryujinx and Yuzu, you will see some increases in performance over the previous generation. First party games are still not all perfect but there are many lower demanding titles that run great.

And for Vita3K we see very good performance on compatible games. With many games you can double the rendering resolution and tweak the graphics for improved visuals.

eGPU support with OCuLink

And don’t forget the GPD WIN 4 2025 has an OCuLink port which you can connect to an eGPU such as the GPD G1 or ONEXPLAYER ONEXGPU 2 eGPU docking station for even more graphics performance. We saw as high as 90 frames per second with the G1, and around 128 FPS with the ONEXGPU 2 on the Cyberpunk benchmark at 1080P.

Final Thoughts on the GPD WIN 4 2025

Time to sum up our thoughts of this GPD WIN 4 2025 review. While the GPD WIN 4 2025 was not the next compact gaming PC we were expecting from GPD, it is a welcome addition to the series as a yearly refresh. If you have the original 6800U model then the performance increases are definitely worth considering, you get a massive bump in gaming performance allowing more modern titles to be playable or run at higher graphics settings or lower TDP’s.

With the GPD WIN 4 2023 (7840U) and GPD WIN 4 2024 (8840U) portable gaming PCs, the benchmark results were quite similar due to the 780M GPU used in both. We do see an overall decent increase in performance when compared with the HX 370 and 890M GPU on the GPD WIN 4 2025. Admittedly it varies between games how much extra performance there is, but generally you will see improvements. 

If you are new to handheld gaming then the GPD WIN 4 2025 is an excellent choice to get started with. The form factor is great, pocketable to an extent, or it can be easily stored in a small bag for easy pick up and up play just about anywhere. The performance for this size handheld is top notch, easily outpacing rivals such as the Steam Deck and ROG Ally.
