The specifics
- Chip
- GMKtec EVO-X3 — Ryzen AI Max+ 395 · Radeon 8060S, 40 CU
- Memory bandwidth
- 256 GB/s
- Usable by the GPU
- 96 GB — Windows lets you dedicate up to 75% of RAM to the GPU (Variable Graphics Memory in AMD Adrenalin). On Linux the amdgpu GTT pool can be raised to roughly 108-120 GB with ttm.pages_limit / amdgpu.gttsize boot parameters. The Windows figure is used here as the conservative one. Measured GPU bandwidth is ~212-215 GB/s of the 256 GB/s theoretical, so estimates here run a little high.
- Power under load
- 150 W (third party measured) — No separate measurement for the X3; ServeTheHome measured 147-160 W at the wall on the EVO-X2, same chip and TDP.
- Availability
- Shipping. Replaced the EVO-X2 in July 2026.
