AMD Ryzen Z2 Go

What the name hides

AMD lists four Zen 3+ CPU cores with eight threads, a 12 compute unit RDNA 2 GPU at up to 2.2 GHz and a 15 to 30 W range. The Z2 Extreme, by comparison, has eight newer cores and a 16 compute unit RDNA 3.5 GPU.

Performance in the Legion Go S

On the Windows Legion Go S, Tom's Guide got about 25 fps in Doom Eternal at native resolution and medium settings, and 10 to 15 fps in Cyberpunk 2077 on the Steam Deck preset; both only became playable at 720p and low settings.

Tom's Hardware measured Cyberpunk 2077 at 35 fps at 800p and 18 fps at 1200p while plugged in. It found the Legion Go S about 10% faster than the original Z1 Extreme Legion Go on battery, and 10 to 20% slower at 40 W plugged in.

Software helps. Pocket Tactics found the Z2 Go SteamOS model ran most games well, though The First Descendant stuttered, and Android Authority notes the Z2 Go can draw 28 W against the Steam Deck's 15 W, which leaves room for more frames.

Battery life

Tom's Hardware measured 1 hour 42 minutes in PCMark 10's gaming test on the Windows Legion Go S, 17 minutes less than the original Legion Go. Android Authority puts demanding AAA play at 90 to 120 minutes on both versions, and Pocket Tactics got two to two and a half hours from indie games on SteamOS.

The Windows model runs quietly. Tom's Guide rarely heard the fans and measured 89.5 °F near the back vents.
