AMD · 12 GB GDDR6 · 432 GB/s

Yes. Radeon RX 7700 XT fits Mistral Nemo 12B Instruct at Q4_K_M, the largest catalog model that clears the fit line at 8K context.

192-bit GDDR6 at 2250 MHz. 2250×8×192/8 = 432 GB/s. Speed uses raw GDDR bandwidth. Infinity Cache is far smaller than model weights, so it is not added. Source.

FAQ

What does the verdict for Radeon RX 7700 XT mean?

Memory is the GGUF file, plus KV cache at 8,192 tokens, plus a 0.5 GiB engine allowance, then 5% headroom. Fits means that total is at most 85% of fast memory. Tight means it still fits. Offload means it needs system RAM. No means it does not fit in VRAM plus system RAM after an 8 GB Windows reserve. The formula is on the methodology page.

What memory did you count as usable?

Fast memory is the full 12 GB. System RAM is assumed to be 32 GB DDR5-5600, with 8 GB kept for Windows, and you can change that on the homepage calculator.

Why is speed a range?

Decode speed is memory bandwidth divided by the bytes read per token. The high end is 80% of that roofline on the weights alone. The low end is 55% once the KV cache at the working context is included. It is not a benchmark.

How should I run Qwen2.5 14B Instruct?

The table uses Q4_K_M. Ollama's matching command is `ollama run qwen2.5:14b`. That blob is the library default and can differ from the cited GGUF by a few hundred MB.
