Windows 11 vs SteamOS Handheld Comparison
Operating System Environment
The Tylvx Mini PC 5.7" Handheld Computer runs Windows 11 out of the box, providing a desktop operating system capable of running standard productivity software, office suites, coding environments, and remote server tools. In contrast, the Lenovo Legion Go S 8" 120Hz runs SteamOS, offering a dedicated gaming operating system. Windows 11 suits you if you need traditional PC software support, browser tasks, and standard desktop utilities alongside games. SteamOS targets streamlined handheld gaming interfaces. Because both operating systems serve distinct user preferences and workflows without one universally outperforming the other across all tasks, this round ends in a tie.
Processor and Graphics
The Lenovo Legion Go S 8" 120Hz includes an AMD Ryzen Z1 Extreme processor reaching speeds from 3.30 GHz up to 5.10 GHz, paired with AMD Radeon 780M graphics. By comparison, the Tylvx Mini PC 5.7" Handheld Computer features an Intel N95 quad-core processor clocking up to 3.4GHz. The Ryzen Z1 Extreme delivers significantly higher clock frequencies, which gives you stronger compute throughput for demanding handheld games. Tylvx designs its N95 setup primarily for lighter workloads like office suites, web browsing, and basic coding tasks. For raw computing and graphics rendering power in handheld titles, the Lenovo hardware holds the advantage.
Memory and Storage Capacity
Storage and system memory dictate how many titles you can install and how smoothly applications run simultaneously. The Lenovo Legion Go S 8" 120Hz provides 32GB of RAM alongside a 1TB SSD, giving you double the memory and double the solid-state capacity found on its competitor. The Tylvx Mini PC 5.7" Handheld Computer includes 16GB of DDR4 RAM and a 512GB SSD. While 16GB and 512GB remain adequate for standard multitasking, document handling, and smaller game installs, the Lenovo handheld gives you substantially more room for modern gaming libraries and heavy memory loads.
Display Size and Refresh Rate
Screen hardware directly influences your visual clarity and gameplay smoothness. The Lenovo Legion Go S 8" 120Hz features an 8-inch screen with a 1920x1200 WUXGA resolution and a 120Hz refresh rate. The Tylvx Mini PC 5.7" Handheld Computer provides a 5.7-inch HD touchscreen, though its spec sheet does not specify a high refresh rate or exact pixel counts beyond HD. The 8-inch panel on the Lenovo unit offers a larger viewing area, sharper pixel density, and high-frame-rate smoothness at 120Hz, delivering a noticeable visual upgrade when you play fast-paced games.
Built-In Inputs and Controls
Physical input methods determine how easily you navigate system settings and type text. The Tylvx Mini PC 5.7" Handheld Computer incorporates a built-in QWERTY backlit keyboard, a multi-finger touchpad, and a G-sensor for automatic screen rotation, making text entry and desktop navigation direct without extra peripherals. In comparison, the Lenovo Legion Go S 8" 120Hz specification sheet does not list an integrated physical keyboard or dedicated typing surface. If you need a pocketable machine where you can quickly write code, manage servers, or input commands without carrying external accessories, the Tylvx model takes this round.
Port Selection and Expandability
Connecting external monitors, networks, and peripherals requires dedicated physical ports. The Tylvx Mini PC 5.7" Handheld Computer includes HDMI 2.1 and DisplayPort 1.2 ports capable of 4K@60Hz video output, dual Type-C ports, and a dedicated 1000M Gigabit Ethernet jack. It also specifies WiFi 6 and Bluetooth 5.2 connectivity. The Lenovo Legion Go S 8" 120Hz data does not specify its video outputs, wired network ports, or wireless revisions. Because the Tylvx device provides explicit desktop-grade expandability for multi-screen setups and wired networking right out of the box, it takes the edge here.
Choosing Your Ideal Handheld Device

You get an AMD Ryzen Z1 Extreme processor reaching 5.10 GHz paired with AMD Radeon 780M graphics. Its 8-inch 1920x1200 panel delivers a 120Hz refresh rate for fluid motion. With 32GB RAM and a 1TB SSD, you have double the memory and storage capacity of the alternative handheld device.

The hardware also includes an integrated 1MP front camera, dual speakers, and G-sensor rotation for pocket-sized productivity.
Mobile users prioritizing high memory and larger display dimensions
If you prefer larger screen area, this model provides an 8-inch WUXGA display running at 1920x1200 resolution. Inside, you get 32GB of memory alongside a 1TB SSD to hold large files. The AMD Ryzen Z1 Extreme APU delivers clock speeds from 3.30 GHz up to 5.10 GHz.
