Legion Go S powered by Z2 Go processor is not that far behind the ROG Ally X in these early benchmarks

Table of Contents
The Lenovo Legion Go is one of the best gaming handhelds out there, competing directly with popular models from other brands like the Steam Deck and ROG Ally. After months of leaks and rumors, the company finally unveiled the Lenovo Legion Go S during CES 2025, a more budget-friendly option for those that want a solid gaming experience on the go.
As far as performance is concerned, while Lenovo has not shared any official benchmarks for the Z2 Go processor, a YouTuber recently compared it to the Z1 Extreme, a powerful CPU found in the ROG Ally X and Lenovo Legion Go – and the results are pretty impressive. The Go S will also be the first third-party SteamOS handheld with a newer variant arriving this May.

Lenovo Legion Go S (Z2 Go) tested against ROG Ally X (Z1 Extreme)
According to the official specifications, the Lenovo Legion Go S will initially come packed with the Ryzen Z2 Go processor, a less powerful version of the Z2 and Z2 extreme CPUs being offered in the upcoming Lenovo Legion Go 2. It has four cores and eight threads, paired with a max frequency of up to 4.3 GHz. It also has a 10 MB cache size and a cTDP of between 15 to 30W.
Recently, YouTuber FPS Vn tested the Lenovo Legion Go S against the ASUS ROG Ally X in three games. For those who don’t know, the ROG Ally X is powered by the Z1 Extreme processor, which has 8 cores and 16 threads – double what the Z2 Go offers. On top of that, it also has a boost frequency of 5.1 GHz. However, despite having much weaker specs than the Z1 Extreme, the Z2 Go is only 10% slower. Here’s how both handhelds performed:
Lenovo Legion Go S (Z2 Go) average FPS | ROG Ally X (Z1 Extreme) average FPS | |
---|---|---|
Black Myth Wukong (15W) | 36 | 40 |
Black Myth Wukong (20W) | 30 | 32 |
Black Myth Wukong (30W) | 60 | 64 |
Cyberpunk 2077 (15W) | 50 | 54 |
Cyberpunk 2077 (20W) | 45 | 47 |
Cyberpunk 2077 (30W) | 61 | 66 |
Ghost of Tsushima (15W) | 62 | 66 |
Ghost of Tsushima (20W) | 48 | 52 |
Ghost of Tsushima (30W) | 62 | 66 |
As you can see in the table above, the difference in performance isn’t that significant, with the Legion Go S being only 9-10% slower on average than the ROG Ally X. For a budget handheld, the Legion Go S delivers solid performance. The initial starting price for the Go S is $729.99 (pre orders recently went live), but a cheaper variant is slated for May starting from $599.99, with the SteamOS version even cheaper at $499.99. With that in mind, it’s shaping up to be a fantastic alternative to the Steam Deck.
Comparively, the ROG Ally X retails at $799. And aside from that, the new AMD Ryzen Z2 series processors also promise to solve battery life issues on ROG Ally and Legion Go handhelds.
