Spec Comparison: 16GB vs 64GB Handhelds
System Memory Capacity
System memory dictates how much data your handheld can hold for immediate processing during active gameplay and background tasks. The Valve Steam Deck 64GB Handheld PC lists 64GB of RAM in its hardware specifications, providing substantial memory overhead for multitasking and demanding PC environments. In comparison, the Lenovo Legion Go S 8" 120Hz comes equipped with 16GB of RAM. While 16GB meets the operating requirements for many modern titles and general Windows navigation, 64GB gives you four times the memory capacity. If you prioritize having maximum RAM on paper for memory-intensive operations, the Valve Steam Deck holds the measurable hardware advantage in this category.
Built-In Storage Capacity
Local storage determines how many game installs and updates you can keep on your handheld without needing expansion cards. The Lenovo Legion Go S 8" 120Hz provides 512GB of internal storage, offering ample room for multiple modern PC installations right out of the box. Conversely, the Valve Steam Deck 64GB Handheld PC comes with 64GB of base storage capacity. Modern game file sizes often exceed 50GB, meaning a 64GB drive can fill up after installing just one standard title or critical system updates. Because the Lenovo Legion Go S supplies eight times the native capacity, it gives you significantly more onboard installation space.
Display Size and Refresh Rate
Screen specifications directly impact visual clarity and motion fluidity during gameplay. The Lenovo Legion Go S 8" 120Hz features an 8-inch PureSight IPS screen with a 120Hz refresh rate, 500 nits of brightness, and 100% sRGB color accuracy. This display also includes 10-point touch support, allowing responsive navigation directly on the panel. In contrast, the provided specifications for the Valve Steam Deck 64GB Handheld PC do not list screen dimensions, refresh rate, touch capabilities, or brightness metrics. Because the Lenovo Legion Go S documents a high-refresh 120Hz 8-inch IPS panel, it provides confirmed, faster visual output and precise input specifications.
Unit Weight and Dimensions
Handheld dimensions and weight determine overall handling comfort during long sessions. The Valve Steam Deck 64GB Handheld PC weighs 1.54 pounds, measuring 11.7 inches in length, 4.61 inches in width, and 1.93 inches in height. By comparison, the Lenovo Legion Go S 8" 120Hz weighs slightly more at 1.63 pounds, with measurements of 11.8 inches long, 5.02 inches wide, and 1.71 inches high. While the Lenovo device is slightly thinner, the Valve Steam Deck is narrower across and weighs 0.09 pounds less. For portable use where every ounce matters in your hands, the lighter weight gives the Valve Steam Deck the edge.
Processor and Operating System
Core processors and software platforms define what games launch and how fast they execute. The Lenovo Legion Go S 8" 120Hz specifies an AMD Ryzen Z2 Go processor, integrated AMD Radeon graphics, and the Windows 11 operating system. This Windows configuration enables native compatibility with various PC game launchers and services, including Legion Space. On the other hand, the data for the Valve Steam Deck 64GB Handheld PC notes PC platform support but omits specific processor, graphics card, and operating system details. With documented AMD Ryzen processing hardware and an established Windows 11 environment, the Lenovo Legion Go S provides clear platform specifications.
Which Handheld Gaming PC to Choose
Players prioritizing high-refresh visuals and larger storage capacity
You receive an 8-inch PureSight IPS screen with a 120Hz refresh rate and 500 nits brightness. It features an AMD Ryzen Z2 Go processor, 512GB of storage, and a 55.5Whr battery. This setup provides smooth visuals, Windows 11 compatibility, and ample onboard space for games without adding external memory.
Users seeking maximum system memory for intensive operations
This model lists 64GB of RAM in its specifications, offering substantially higher memory allocation than typical handheld configurations. If your PC applications require extensive system memory for data processing, this device matches that requirement directly. At 1.54 pounds, the black console is also lighter than the 1.63-pound alternative.
Gamers wanting integrated controls and higher battery capacity
This handheld includes a 55.5Whr battery alongside ergonomic Legion TrueStrike controllers for extended gaming sessions. You get AMD Radeon graphics, Legion ColdFront cooling technology, and 100% sRGB color accuracy on the 8-inch panel.

Frequently asked questions
How does 16GB RAM compare to 64GB RAM in handheld gaming PCs?
16GB RAM handles standard operating system tasks and modern PC games smoothly on handheld devices. A 64GB memory configuration offers four times the capacity, giving you excess bandwidth for heavy background utilities or specialized memory allocations without paging files. However, 16GB remains the typical baseline across most portable gaming hardware.
What processor powers the 16GB Lenovo Legion Go S?
The Lenovo Legion Go S uses an AMD Ryzen Z2 Go processor paired with integrated AMD Radeon graphics. This processing setup works directly with the 16GB memory pool to run portable PC and mobile platform titles. It delivers consistent performance alongside the system's 512GB internal storage drive.
How heavy are 16GB and 64GB handheld gaming PCs?
Handheld chassis weights stay fairly close regardless of memory capacity. The 64GB Valve Steam Deck weighs 1.54 pounds, measuring 11.7 inches long and 1.93 inches tall.
