In our battery tests running Cinebench on a loop, with full screen brightness at 28W TDP we got similar battery lifes of 1 hour 10 minutes on the 8840U model, 1 hour 11 minutes on the HX 365 and 1 hour 13 minutes on the HX 370 model. Around 10 minutes more battery life than the GPD Win 4 2025 and Mini. Your average usage will of course be higher, in the 3 to 6 hours range depending on demand.

In our highest fan noise and thermal tests, also performed while running Cinebench, we again got very similar results across the three models. The 8840U and HX 365 got 54 dB fan noise and 45 °C temperature, and the HX 370 got 55 dB and 45 °C. All very close battery life, fan noise and temperatures. 

System Benchmarks

As part of our ONEXPLAYER ONEXFLY F1 Pro review we will be running some benchmarks. We will compare the three models against each other, as well as compare the performance with other HX based compact gaming PCs.

PCMARK

PCMARK tests the performance of your day to day tasks which includes web browsing and video conferencing, through to more demanding workloads, such as working with large office documents, image editing and rendering.

We see slightly lower results with the ONEXPLAYER ONEXFLY F1 Pro when compared to the GPD gaming handhelds. These are combined scores so it could be slightly slower SSD speeds for example affecting them.

Cinebench

Cinebench tests the CPU’s single and multi-core performance.

We naturally see lower scores for the older 8840U processor. With the HX based models we see similar scores for single-core performance. The HX 370 takes the lead on multicore performance, and we can see a considerable drop on the HX 365, though it is the same as the GPD WIN Mini 2025 HX 370 performance.

Geekbench 6

Geekbench 6 also tests the single and multi-core performance.

For single core performance we see fairly similar scores which is expected. On multi-core the ONEXPLAYER ONEXFLY F1 Pro HX 370 again takes the lead, the HX 365 does well beating the GPD WIN MAX 2 2025 and Win 4 devices.

3DMARK

On 3DMARK we are running the Time Spy, Night Raid and Fire Strike benchmarks.

Once the CPU and GPU come in to play there are some interesting results. We do see the ONEXPLAYER ONEXFLY F1 Pro HX 365 have lower results in two of the three benchmarks when compared with the 8840U model. The HX 370 scores improve on the other two models, but do struggle to keep up with the GPD devices. It will be interesting to see if this continues in the games benchmarks which are up next.

Gaming Benchmarks

And continuing our ONEXPLAYER ONEXFLY F1 Pro review with some gaming benchmarks. We will be running the handheld gaming computers at both 1080P and 720P, across a range of TDPs to see how the performance differs.

Forza Horizon 5

For Forza Horizon 5, we see that at 1080P, the F1 Pros have noticeable lower performance than the GPD devices. And at 720P the GPD devices keep the advantage until we get to around 10W TDP where the ONEXPLAYER ONEXFLY F1 Pro has similar or higher frame rates.

Shadow of the Tomb Raider

For Shadow of the Tomb Raider, we again see some differences. At 1080P the F1 PROs are behind the GPD devices. And at 720P we see improved results at 28W TDP, and as we lower the TDP, the frame rates start to overtake the GPD devices.

Cyberpunk

For Cyberpunk we again see the F1 PRO trailing behind the GPD devices. At 720P the trend continues at the higher TDPs, but as we lower them, we see improved frame rates overtaking the GPD.

Benchmark Summary

The ONEXPLAYER ONEXFLY F1 Pro’s compared with the GPD mobile gaming PCs clearly have some differences in performance. Throughout the tests we see overall lower performance while at 28W TDP on the F1 Pro. And when we lower the TDP, we see similar or higher scores than the GPD. This is most likely how the CPU and GPU power management is configured and can be tweaked with 3rd party software such as Handheld Companion.

For an out of the box experience, with those that just want a plug and play experience, and do not wish to tweak settings, the GPD devices may be the better option if you are planning to play at higher TDPs.

Gaming Performance

Now for some games at playable settings on the HX 370 model. Where possible above 60 FPS and with different TDP settings.

Indiana Jones & The Great Circle

For Indiana Jones & The Great Circle we are running at 720P on the low graphics settings, set to 35 frames per second at 28W TDP.

Lonely Mountain

For Lonely Mountain, we couldn’t quite get 144Hz, but you can choose either 720P Low graphics if you want 120FPS or you can go higher resolution and/or graphics settings for 60+ FPS.

Carrion

Carrion is a fairly low demanding game which runs at 1080P resolution at only 5W TDP.

TMNT Shredders Revenge

Another low demanding game that is no problem at 1080P resolution and lowering the TDP down to 5W to save battery life.

Overthrown

Overthrown runs very well. You can set the resolution to 1080P with AMD FSR Balanced enabled for 60+ frames per second. If you want a little extra graphics quality you could change the FSR but I couldn’t really see much difference.

Emulation Performance

For running emulators on the ONEXPLAYER ONEXFLY F1 Pro series you will be able to run up to the PlayStation 3 era with little issues. The main differences between the 8840U and HX models are that extra bump in performance which comes into play on the higher end or demanding emulators such as RyuJinx and Vita 3K.

Going back a few console generations, we see excellent performance on DuckStation. You can increase the rendering resolution to 1080P and enable various graphics tweaks to improve the visuals.

And it is much the same with PCSX2, compatible games will run great and you will again have no issues cranking up the rendering resolutions and graphics setting. 

With RPCS3 you will see good performance across the F1 Pro range. You will have shader caching while playing compatible games, but this shouldn’t affect gameplay, even on the 8840U model.

And with the Vita3K emulator you can enjoy a decent number of compatible games. Depending on how demanding the game is you can increase the rendering resolutions for nicer visuals.

eGPU Support

While the ONEXPLAYER ONEXFLY F1 Pro series does not have an OCuLink port, you can still use the high speed USB 4 port to connect to an eGPU. You now have a choice of the ONEXGPU with AMD Radeon RX 7600M or the new and higher performing ONEXGPU 2 with AMD Radeon RX 7800M. 

These eGPUs provide a massive boost in GPU performance, not only are they great for gaming, but also for video editing for example.

Final Thoughts

The ONEXPLAYER ONEXFLY F1 Pro series offers a good range of CPU configurations depending on your budget and requirements. For the 32GB 2TB configuration, the 8840U is around $260 lower in price than the HX 365 model, which in turn is around $120 lower than the HX 370 model. The price versus performance is about right for the specifications.

In terms of performance, we did see varied lower results than the GPD devices when running at 28W TDP, and as we lower it we saw closer or higher scores. If you don’t mind spending a little time you can tweak a few settings, this will level the CPU & GPU power performance to be more in line with the GPD’s at higher TDP performance.

The ONEXPLAYER ONEXFLY F1 Pro however remains a portable gaming computer to definitely consider. The form factor with large 7” OLED supporting 144Hz looks amazing, and it has that advantage over the GPD devices displays. While the size is not quite as portable as say the WIN 4 and Mini models, the F1 Pro can easily fit in a small bag or rucksack for example.

If the GPD WIN 4 and Mini 2025 handheld gaming computers are not your thing, then the ONEXPLAYER ONEXFLY F1 Pro series are a great alternative!
