GPD Win Mini – the clamshell king of 2025

As 2025 concludes, the Win Mini 2025 deserves particular attention: it represents the third generation of GPD’s clamshell design and, thanks to its AMD Ryzen™ AI 9 HX 370 processor, stands as the most powerful clamshell-format handheld computer available. This year’s refresh represents not merely a cosmetic update, but a thoughtfully engineered evolution addressing the practical limitations of its predecessor.

Despite visual similarities to the 2024 model, the engineering differences run considerably deeper than initial appearances suggest:

  • Enhanced Processing Power: The new AMD Ryzen AI 9 HX 370 APU delivers significant improvements in performance, featuring 12 cores, 24 threads, and a boost clock of 5.1 GHz.
  • Comprehensive Thermal Redesign: The cooling system has been completely overhauled to accommodate the new APU’s thermal demands (28–35W TDP).
  • Standardized Storage Format: The 2025 model adopts standard M.2 2280 SSDs (replacing the 2230 form factor), dramatically expanding available upgrade options.
  • Ergonomic Material Refinement: The rear chassis now features a matte plastic finish that is more pleasant to the touch and reduces glare and fingerprinting compared to glossy surfaces.
  • Improved Input Ergonomics: The joystick mode toggle switch has been repositioned for more convenient access.

Notably, relatively few internal components are carried over from the previous generation, underscoring the depth of this redesign rather than a typical point revision.

The USB4 port enables connection to external GPU docks (such as the GPD G1), effectively converting the Win Mini into a desktop machine when docked.

The Ryzen AI 9 HX 370 represents a significant architectural advancement. Unlike previous-generation processors that treated the NPU as an ancillary accelerator, Zen 5’s XDNA 2 NPU is fully integrated into the compute fabric, enabling on-device inference of quantized models like GPT OSS 20B without cloud dependencies.

The 64GB configuration, with LPDDR5x memory at 7500 MT/s (configurable to 8000 MT/s), enables practical local inference of mid-tier language models like Qwen 3 Next 80B and PrimeIntellect-3 106B with acceptable latencies.

Detailed performance test results for the GPD Win Mini 2025, including comparative analysis against the previous generation and contemporary handheld devices, are available in the comprehensive benchmarking study linked below:
Benchmarking UMPCs of the second epoch.

Conclusion

Handheld computing enthusiasts rightfully prioritize portability — it’s the defining characteristic that distinguishes these devices from traditional computers. Any form factor expansion carries inherent risk.

The Win Mini 2025’s slight increase in size is offset by substantive engineering gains. The new Ryzen AI 9 HX 370 delivers strong multi-core improvements, while the thermal redesign maintains safe temperatures and reasonable acoustics. Standard M.2 2280 storage now enables practical upgradeability with hundreds of available options. These improvements address real limitations of the previous generation—genuine friction points that affected daily usability.

Benchmarking UMPCs of the second epoch

Introduction

"An ultra-mobile PC (ultra-mobile personal computer or UMPC) is a miniature version of a pen computer, a class of laptop whose specifications were launched by Microsoft and Intel in spring 2006." (c) Wikipedia. That was the dawn of the first UMPC epoch. This epoch did not last too long, because in the early 2010s major UMPC manufacturers ended its product lines. Few years later new manufacturers emerged and recreated UMPC market. The major one was the Chinese company GPD. GPD started the second UMPC epoch by releasing gaming handheld GPD Win in 2016 and the general purpose device GPD Pocket in 2017. Since then a whole bunch of UMPC devices were released. In this article, we compare the performance of various UMPC devices from the second epoch, ranging from the very first GPD Win to the most powerful clamshell to date—the GPD Win Mini 2025. In total, 12 different devices will be examined in this comparison.

Disclaimer. This article is not a comprehensive performance analysis of the 2-nd era UMPCs. All the test items are taken from my collection. Therefore the number of test items is quite limited. In case I add any new corresponding items to my collection, this benchmark survey might be extended as well.

CPU & Memory performance

Geekbench test results
AIDA64 test results
CPU-Z test results
PassMark Performance Test results

Single-core processor performance continues to grow, but the rate of growth is quite modest. However, total multi-threaded performance has increased 20-fold over the last 9 years!

SSD performance

CrystalDiskMark test results

Storage read and write speeds of have increased tens of times over the last 9 years. However, the highest performance is demonstrated not by the GPD Win Mini 2025, but by the GPD Pocket 3. The latter features an incredible read speed of 6 GB/s. It is possible that the storage performance of the GPD Win Mini 2025 could be improved by replacing the drive.

3D performance

3DMark test results
Unigine Heaven test results

Few notes:

  1. Performance of Iris Xe (One-Netbook OneGx1 Pro i7) was just outstanding as of 2021.
  2. The performance of the Radeon 890M (GPD Win Mini 2025) has doubled compared to the Iris Xe.
  3. Tiger Lake supports Thunderbolt 4, which allows to connect eGPU to the UMPC. eGPU can improve 3D performance of OneGx1 Pro by at least 4 times. See details here: Benchmarking OneGx1 Pro with eGPU.
  4. Performance of A1 is significantly lower than performance of OneMix 2s, which is based on the same Intel Core m3-8100Y.
  5. Despite the similar brand name "UHD Graphics", the GPU performance in the i3-1110G4 is 2+ times higher than the performance of the m3-8100Y and N100.
  6. Despite the Intel N150’s relatively modest performance compared to flagship devices, it is worth noting that the N150 is noticeably more performant in 3D than the Intel N100.

Conclusion

Since the GPD Win (released in 2016) performance of UMPCs for 2025 has changed as follows:

  • CPU performance in single-threaded mode has increased by about 9 times and has not grown significantly in the last 3 years.
  • CPU performance in multithreaded mode has increased by about 20 times and has roughly doubled over the past 3 years.
  • RAM also demonstrates impressive performance growth—a 10-fold increase over 9 years.
  • SSD read speed has increased 40-fold, while write speed has increased nearly 60-fold.
  • GPU performance increased by about 35-40 times, depending on the task.
