AMD Gorgon Halo 192GB vs NVIDIA H100 NVL for local LLMs
8 reports on the AMD Gorgon Halo 192GB and 1 on the NVIDIA H100 NVL
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 NVIDIA H100 NVL has 177.7 generation 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 14.3x higher on the NVIDIA H100 NVL (273 GB/s on the AMD Gorgon Halo 192GB, 3,900 on the NVIDIA H100 NVL).

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. How to read these

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.
