GamePad Digital (GPD) is recognized as a game-changer in smart gaming, office and handheld consoles, committed to bring consumers leading-edge innovations and ultimate personalized experiences. GPD WIN 5, its latest masterpiece, breaks the limits of “handheld console productivity” and its innovative adoption of BIWIN Mini SSD brings users ultra-fast loading, free expansion, and reliable on-the-go data storage experiences.

01 A Performance “Monster” in Your Palm, Ideal for AAA Games

In order to keep pursuit of being compact and powerful meanwhile, GPD WIN 5 is equipped with AMD Ryzen AI Max+ 395 processor and 128GB LPDDR5X 8000 MT/s memory, with Mini SSD as an expandable memory solution. This robust combination of memory and computing makes it able to support smooth operation of 70-billion-parameter large models, handle professional workloads like 8K video rendering and scientific computing and deliver high frame rates and low latency for an immersive AAA gaming experience.

The BIWIN Mini SSD in the GPD WIN 5 is a highly integrated storage solution designed specifically for on-device AI. Based on PCIe 4.0 ×2 and NVMe 1.4 protocols, it offers sequential read speeds up to 3700MB/s and 850K IOPS 4K random read performance, continuously feeding data to the processor and integrated graphics. Whether loading large model weights quickly or seamless texture streaming in AAA games, it effectively prevents performance bottlenecks.

02 Innovative “Expandability” Design, Super Portable Experience

The GPD WIN 5 weighs just 565 grams with a compact size of 195.6mm × 99.5mm × 22.5mm. From a hardware architecture perspective, it features an innovative multi-level expandable design to greatly enhance portability and control over system customization. Beyond its built-in M.2 2280 SSD, the GPD WIN 5 becomes the first handheld gaming console globally to integrate a Mini SSD slot. With flexible memory expansion options covering 512 GB / 1 TB / 2 TB and a maximum total capacity of up to 6 TB, players can carry an entire game library on-the-go.

With a footprint of just 15 × 17 × 1.4 mm, the Mini SSD is only slightly larger than a microSD card, yet delivers up to five times the performance. At just 1/14 the size of a standard M.2 2280 SSD, it offers performance on par with high-end PCIe Gen4 SSDs. Users can repurpose it as a secondary system drive, SteamOS boot disk, or dedicated work drive. Thanks to its standardized slot design, memory expansion becomes as simple as swapping a SIM card for users, significantly reducing expansion complexity while maximizing flexibility, maintainability, and long-term usability.

The GPD WIN 5 also adopts a hot-swappable battery design, enabling users to extend runtime indefinitely with spare batteries and fully eliminate battery anxiety. Its lightweight form factor and expandable hardware design make it a perfect companion for travel, outdoor adventures, and other power-sensitive mobile use cases.

03 High-Efficiency Thermal Architecture for Sustained Performance

IP68 Dust & Water Resistance for High-Mobility Scenarios

Frequently used in commuting, business travel, and outdoor environments, handheld gaming devices are exposed to demanding conditions such as drops, vibration, and rapid temperature fluctuations. To address this, the GPD WIN 5 introduces the new cooling architecture dubbed “Frostwind”, which uses two fans and four heat pipes to tame the high waste heat. Even during prolonged AAA gaming or multi-tasking, it maintains stable performance without thermal throttling or stuttering.

Meantime, BIWIN Mini SSD are equipped with multi-level reliability technologies, including self-developed LDPC, dynamic/static wear leveling and intelligent thermal throttling, to offer sustained performance during high-load gaming and long-time rendering. Tested through 1000+ validations, it supports 3-meter drop-resistance and 10–2000 Hz vibration and shock tolerance, with MTBF reaching 1.5 million hours.

04 Empowering Terminal Innovation and Redefining the Hardware Experience

This collaboration with GPD WIN 5 serves as a strong testament to BIWIN Mini SSD’s top-notch product capability, as well as a perfect example of efficient coordination and value co-creation across the industry chain. Beyond as a high value-added and differentiated memory solution for brand customers, it also offers end users more ungraded, convenient and smooth digital experiences.

• For GPD, the Mini SSD’s standardized, highly reliable, solder-free design significantly simplifies supply chain operations and reduces BOM management complexity, enabling faster product iteration and time-to-market.
  
  
• For users, pluggable and expandable storage provides greater convenience, control, and long-term usability, redefining freedom in personal hardware configuration.
  
  
• For the industry, this collaboration validates the Mini SSD’s real-world application value and establishes a new hardware paradigm for handheld consoles, mini PCs, robotics platforms, and other intelligent terminals.

Beyond market adoption, the Mini SSD’s technological excellence has earned recognition from leading international authorities. The product has received TIME’s “Best Inventions of 2025” and the Embedded World 2025 “Best-in-Show”. BIWIN itself was also awarded the “2025 ‘China Chip’ Outstanding Supporting Service Enterprise” title in recognition of its innovation breakthroughs.

Building on the successful deployment of Mini SSDs in flagship platforms from GPD, OneXPlayer, and beyond, BIWIN will further collaborate with global device makers, ecosystem partners, and industry standards bodies to accelerate large-scale commercialization and ensure innovative storage technologies deliver real value to end users.
