GPU comparison FAQ

Which is faster on RTX 4090: mistral-7b or nemotron-51b?

This RTX 4090 comparison shows VRAM fit and quality data for mistral-7b vs nemotron-51b, but one or both decode-speed benchmarks are still missing.

Do both models fit on RTX 4090?

mistral-7b: ✓. nemotron-51b: ✗ No. The fit labels use Q4_K_M VRAM estimates and the benchmark data available for this GPU.

How much VRAM do these models need?

mistral-7b needs about 4.7GB in Q4_K_M; nemotron-51b needs about 30.6GB in Q4_K_M.

Why can speed differ by GPU?

Local LLM speed depends on GPU memory bandwidth, backend, quantization, context length, and whether the model fits entirely in VRAM or unified memory.

How can I correct this comparison?

Use the GitHub correction link on this page with your GPU, model, quantization, context length, and measured decode tokens per second.
