Comparing Z2 Go and AI 9 Handhelds
Processor and Graphics
You get distinct silicon platforms between these two machines. The Lenovo Legion Go S uses the AMD Ryzen Z2 Go processor paired with integrated AMD Radeon graphics for handheld gaming. In contrast, the GPD Pocket 4 runs on the higher-tier AMD Ryzen AI 9 HX 370 processor alongside an integrated AMD Radeon 890M GPU built on RDNA 3.5 architecture. The GPD model also includes AMD artificial intelligence processing hardware. While the Legion Go S delivers standard portable graphics capabilities, the Pocket 4 provides a more advanced GPU architecture and onboard AI acceleration directly inside its compute package.
Memory and Storage Capacity
Storage and memory allocations vary substantially across these systems. The Lenovo Legion Go S provides 16GB of system memory alongside a 512GB solid-state drive for game installations and file caching. The GPD Pocket 4 supplies 32GB of LPDDR5X RAM and a 4TB PCIe Gen4 M.2 NVMe SSD. Having 32GB of memory allows the Pocket 4 to allocate more shared video memory to the graphics chip while running background applications. Its 4TB solid-state drive also holds significantly more game libraries than the 512GB drive on the Lenovo model without requiring an immediate storage upgrade.
Display Size and Refresh Rate
Both handhelds feature high-refresh IPS touchscreens with 10-point touch support, but their visual specifications diverge. The Lenovo Legion Go S carries an 8-inch PureSight IPS panel running at 120Hz, delivering 500 nits of brightness and 100% sRGB color accuracy. The GPD Pocket 4 incorporates a larger 8.8-inch IPS touchscreen with a sharper 2.5K resolution and a faster 144Hz refresh rate. While the Lenovo device publishes specific panel brightness and color coverage ratings, the GPD Pocket 4 delivers more screen real estate, higher pixel density, and a faster refresh cycle for motion rendering.
Battery Capacity
Unplugged runtimes depend heavily on total battery volume. The Lenovo Legion Go S includes a 55.5Whr battery to support extended mobile play sessions away from wall outlets. Meanwhile, the GPD Pocket 4 carries a smaller 44.8Wh battery, which GPD rates for up to 9 hours of video playback. The Pocket 4 compensates somewhat by supporting 100W PD fast charging, allowing fast top-ups between sessions. Even so, the Lenovo Legion Go S holds a clear advantage in raw battery capacity, giving you roughly 10.7 more watt-hours of energy reserve for portable handheld sessions.
Form Factor and Controls
Physical layout changes how you interact with each device. The Lenovo Legion Go S is built as a dedicated gaming handheld measuring 11.8 by 5.02 by 1.71 inches and weighing 1.63 pounds. It integrates ergonomic Legion TrueStrike controllers with anti-slip textures and front-firing speakers. The GPD Pocket 4 uses a 2-in-1 mini laptop chassis measuring 8.11 by 5.67 by 0.87 inches and weighing 1.6 pounds. The Pocket 4 converts between tablet and laptop modes with modular port support, but the Legion Go S gives you integrated physical gamepad controls out of the box.
Choosing Your Handheld Gaming PC
Players prioritizing dedicated console ergonomics and battery watt-hours
You get integrated Legion TrueStrike controllers with anti-slip grip and a 55.5Whr battery for longer sessions away from wall outlets. The 8-inch 120Hz IPS screen delivers 500 nits of brightness with 100% sRGB color coverage. Built-in ColdFront cooling keeps the AMD Ryzen Z2 Go processor stable during extended gameplay.
Power users wanting high RAM and massive storage
You receive 32GB of LPDDR5X memory paired with a 4TB PCIe Gen4 SSD. This configuration gives you eight times the storage capacity of the alternative. The AMD Ryzen AI 9 HX 370 processor and Radeon 890M graphics handle heavy computational demands. Triple display connectivity runs via HDMI 2.1 and two USB-C ports.
Users seeking a sharper display with faster refresh
You get an 8.8-inch 2.5K IPS touchscreen operating at 144Hz for smoother frame pacing and higher visual detail. The 2-in-1 design switches between laptop and tablet orientations. Fast 100W PD charging restores power to the 44.8Wh battery quickly. The AMD Radeon 890M integrated GPU drives graphics across your games.
