Detailed Handheld Gaming PC Comparison
Processor and Graphics Hardware
Lenovo Legion Go S 8" 120Hz features the AMD Ryzen Z1 Extreme processor running from 3.30 GHz up to 5.10 GHz, paired with integrated AMD Radeon 780M graphics. Product B, the GPD Pocket 4 Mini Laptop, runs the newer AMD Ryzen AI 9 HX 370 processor alongside integrated AMD Radeon 890M graphics built on RDNA 3.5 architecture. The Ryzen AI 9 HX 370 also incorporates dedicated AI compute capabilities. If you prioritize raw generation upgrades in graphics and compute silicon, the Radeon 890M and Ryzen AI architecture give the GPD Pocket 4 a measurable technical hardware advantage over the Z1 Extreme configuration in the Lenovo Legion Go S.
Storage Capacity
Lenovo Legion Go S 8" 120Hz comes equipped with a 1TB SSD. In contrast, the GPD Pocket 4 Mini Laptop includes a 4TB PCIe Gen4 M.2 NVMe SSD. Modern game installs frequently require 50GB to 150GB of space each, making local capacity an important factor for handheld gaming setups. While a 1TB drive holds a solid library of titles, the 4TB capacity in the GPD Pocket 4 provides quadruple the onboard room for games, media, and applications without needing immediate upgrades. The GPD Pocket 4 wins this round based strictly on its integrated storage volume.
Display and Refresh Rate
Lenovo Legion Go S 8" 120Hz features an 8-inch screen with a 1920x1200 WUXGA resolution and a 120Hz refresh rate. The GPD Pocket 4 Mini Laptop carries an 8.8-inch IPS touchscreen display offering a 2.5K resolution and a 144Hz refresh rate with 10-point touch support. The GPD Pocket 4 provides a larger viewing area, sharper pixel density via 2.5K rendering, and a faster 144Hz panel for slightly smoother motion clarity. If you look strictly at panel dimensions, pixel count, and maximum refresh capabilities, the GPD Pocket 4 holds the clear spec advantage over the Lenovo Legion Go S.
Operating System and Interface
Lenovo Legion Go S 8" 120Hz ships with SteamOS as its preinstalled operating system. The GPD Pocket 4 Mini Laptop lists PC platform compatibility without a specific gaming-first interface detailed in its base configuration. SteamOS provides an interface specifically structured for handheld gaming navigation, controller input mapping, and quick sleep-and-resume functions. While general PC software allows versatile desktop utility, SteamOS gives the Lenovo Legion Go S an operating system optimized directly for dedicated console-like portable play. For users wanting a streamlined gaming environment right out of the box, the Lenovo Legion Go S takes the edge.
System Memory
Both devices provide substantial memory pools for portable computing. The Lenovo Legion Go S 8" 120Hz features 32GB of RAM. The GPD Pocket 4 Mini Laptop also includes 32GB of LPDDR5X RAM. In modern handheld gaming systems, system memory is shared between central processing tasks and integrated graphics allocations. Having 32GB allows both devices to allocate sufficient video memory to the GPU while leaving ample headroom for operating system tasks and background services. Because both the Lenovo Legion Go S and the GPD Pocket 4 provide an identical 32GB total memory ceiling, this round results in a tie.
Which AMD Handheld Should You Pick
Handheld gamers prioritizing a dedicated SteamOS gaming experience
You get an 8-inch screen with a 1920x1200 resolution and a 120Hz refresh rate. It runs SteamOS directly, pairing the AMD Ryzen Z1 Extreme processor and 32GB of RAM with a 1TB SSD. This setup suits you if you want a dedicated console-style operating system built strictly around portable gaming.
Mobile users needing extensive onboard storage and high-refresh visuals
You receive 4TB of PCIe Gen4 SSD storage alongside a 144Hz, 2.5K IPS touch display. The larger 8.8-inch panel gives you higher pixel density and faster refresh rates.
