AMD Gorgon Halo 192GB vs M3 Ultra 96GB for local LLMs

7 reports on the AMD Gorgon Halo 192GB and 6 on the M3 Ultra 96GB

Which is faster for local LLMs?

On gpt-oss 117B · 5.1B active at 4-bit, the AMD Gorgon Halo 192GB has 49.0 generation tokens/s (2 runs); prompt processing 760.0 tokens/s (2 runs); the M3 Ultra 96GB has 73.0 generation tokens/s (one run); prompt processing 347.0 tokens/s (one run). Those are community reports whose engines and settings differ, so the gap is a rough sign, not a controlled measure of the two cards. Memory bandwidth, which caps how fast a card can write, is 3.0x higher on the M3 Ultra 96GB (273 GB/s on the AMD Gorgon Halo 192GB, 819 on the M3 Ultra 96GB).

Measured on both

Generation and prompt processing speeds from plain runs (one device, one request, no speculative decoding, the whole model in the device's memory) of the same model size at the same bit class. Each side shows the engines and reported context behind its median. Context can mean a configured window or prompt depth, so these are community comparisons with differing settings.
