Strix Halo (Ryzen AI Max+ 395)

Strix Halo is AMD's codename for the Ryzen AI Max+ 395, the APU behind nearly every 128GB local-AI mini PC. It pairs a 16-core Zen 5 CPU, a Radeon 8060S iGPU (40 CU, RDNA 3.5), and a 50-TOPS XDNA 2 NPU with a 256-bit LPDDR5X-8000 memory controller — 256 GB/s theoretical, ~215 GB/s real. That memory setup, roughly 2× a normal desktop APU, is what lets boxes like the GMKtec EVO-X2, Framework Desktop, and HP Z2 Mini expose up to 96GB as VRAM and run 70B-class models. Its weakness is bandwidth, far below a discrete GPU, so dense 70B inference runs in the single-digit tokens/sec.

Strix Halo is the default platform for 'I want to run big models cheaply.' The boxes differ mainly in IO, cooling, and price — not silicon — so once you've settled on the chip, pick on 10GbE, chassis, and warranty.
