NVIDIA CMP 170HX 64GB (unlocked) vs AMD Gorgon Halo 192GB for local LLMs

12 reports on the NVIDIA CMP 170HX 64GB (unlocked) and 6 on the AMD Gorgon Halo 192GB

Which is faster for local LLMs?

On Qwen3.8 27B at 8-bit, the NVIDIA CMP 170HX 64GB (unlocked) has 50.0 generation tokens/s (one run); prompt processing 3468.0 tokens/s (one run); the AMD Gorgon Halo 192GB has 8.1 generation tokens/s (one run); prompt processing 466.0 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 5.5x higher on the NVIDIA CMP 170HX 64GB (unlocked) (1,493 GB/s on the NVIDIA CMP 170HX 64GB (unlocked), 273 on the AMD Gorgon Halo 192GB).

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.

Estimated by the calculator

The quant the calculator recommends for each card and its estimated speed at a 32,768-token context with 32 GB of system RAM, from memory bandwidth and the model's shape. Where a model was also measured above, the measurement wins.
