Comparing Memory and Hardware Performance
System Memory
Memory allocations dictate how much headroom you have for modern games and background services. The HIDevolution ASUS ROG Ally X provides 24GB of LPDDR5X onboard system memory configured in a dual-channel 2 x 12GB arrangement. This setup helps you run memory-heavy titles while leaving ample memory for the operating system. In contrast, the Lenovo Legion Go S comes equipped with 16GB of RAM. While 16GB handles standard PC gaming configurations, the extra 8GB on the ASUS ROG Ally X gives you a noticeable buffer for aggressive memory allocation. Because handheld APUs share memory between the processor and graphics, the 24GB configuration provides superior flexibility.
Screen Size
Display area directly alters your viewing comfort and in-game interface readability. The Lenovo Legion Go S features an 8-inch PureSight IPS screen offering 500 nits of brightness and 100 percent sRGB color coverage. That larger surface gives you more physical viewing space for fine text and HUD markers. Meanwhile, the HIDevolution ASUS ROG Ally X carries a smaller 7-inch IPS-level touch screen. Although both units support touch input, the extra inch on the Lenovo Legion Go S delivers a noticeably larger visual canvas without requiring an external monitor. If you prefer a larger viewing area on the device itself, the Lenovo handheld takes the clear lead here.
Processor Specifications
The processor handles core gameplay logic and physics. The HIDevolution ASUS ROG Ally X is driven by an AMD Ryzen Z1 Extreme processor with 8 cores, 16 threads, a 3.3 GHz base frequency, and boost capability up to 5.1 GHz alongside a 24MB Smart Cache. The Lenovo Legion Go S uses an AMD Ryzen Z2 Go processor with AMD Radeon graphics, though its core counts, thread counts, and boost clock limits are not specified in the listing. With detailed multi-threaded specs and high boost clocks confirmed in the data, the AMD Ryzen Z1 Extreme in the HIDevolution unit offers verified hardware parameters for handling demanding modern tasks.
Storage Capacity
Storage capacity determines how many titles you can store locally at once. The HIDevolution ASUS ROG Ally X includes a 1TB PCIe 4.0 x4 NVMe M.2 2280 solid-state drive for fast boot-ups and load times. On the other hand, the Lenovo Legion Go S provides 512GB of internal storage out of the box. Modern game installations often require dozens of gigabytes each, meaning 512GB can fill up quickly once you install several larger games. By offering double the standard capacity with 1TB of PCIe storage, the HIDevolution ASUS ROG Ally X gives you significantly more local space for your library before you need drive management.
Display Refresh Rate
Refresh rates govern motion clarity and responsiveness when you play fast-action games. Both the Lenovo Legion Go S and the HIDevolution ASUS ROG Ally X deliver a 120Hz refresh rate on their integrated screens. This allows both handhelds to display supported titles at up to 120 frames per second when the hardware pushes sufficient performance. The HIDevolution ASUS ROG Ally X additionally lists a 7ms response time on its panel, while response times are unlisted for the Lenovo display. However, because both screens match each other with identical 120Hz refresh ceilings, neither machine gains an advantage in overall refresh capability during fast-paced motion.
Which Handheld PC Should You Buy?
Players who prioritize larger displays and battery capacity
You get an 8-inch PureSight IPS screen with 500 nits brightness and 100% sRGB coverage. This gives you more viewing area than a 7-inch panel. The 55.5Whr battery supports longer unplugged sessions, while the AMD Ryzen Z2 Go processor handles standard workloads alongside 512GB of internal storage.
Users needing maximum memory capacity and factory storage
You receive 24GB of LPDDR5X RAM, offering 8GB more memory for multitasking and system overhead. It includes a 1TB PCIe 4.0 NVMe SSD, doubling the default storage capacity. The AMD Ryzen Z1 Extreme processor brings 8 cores and 16 threads, reaching boost clocks up to 5.1 GHz for demanding games.
Travelers who prioritize lighter weight and compact dimensions
At 1.49 pounds, this unit weighs less than the 1.63-pound alternative. Its 11-inch length and 4.37-inch width make it easier to pack in smaller bags. You still get a 7-inch 120Hz display with 1080p resolution, paired with 24GB of RAM and 1TB of NVMe SSD space.
