[r/LocalLLaMA] Is memory speed everything? A quick comparison between the RTX 6000 96GB and the AMD W7800 48GB x2.

Summary

A user compared the performance of a single RTX 6000 96GB GPU against two AMD W7800 48GB cards, noting the AMD setup offered significantly higher memory bandwidth at a competitive price. The comparison, using CUDA for NVIDIA and ROCm for AMD, focused on token generation speed for large language models like Deepseek and GLM 5, achieving 25-30 tokens/second on the AMD configuration. This practical test highlights AMD's potential for local LLM inference, especially in multi-GPU setups.
