For each model, the highest-precision quantization that runs entirely in fast memory; otherwise the one with the best result. Speeds are ranges; "estimate" unless a benchmark exists for this exact hardware.

Limits in plain words
48 GB of VRAM holds the weights and KV cache of models up to about Llama 3.3 70B Instruct at Q4_K_M. Bigger models spill into system RAM and slow down sharply: generation speed is then limited by RAM bandwidth, not by the GPU.

Frequently asked questions
Which LLMs can the RTX A6000 run?
Entirely on the GPU: Qwen2.5 72B Instruct (IQ4_XS), Llama 3.3 70B Instruct (Q4_K_M), DeepSeek R1 Distill Llama 70B (Q4_K_M), Mixtral 8x7B Instruct (Q6_K), Qwen3 32B (Q8_0), DeepSeek R1 Distill Qwen 32B (Q8_0), Qwen2.5 32B Instruct (Q8_0), Qwen2.5 Coder 32B Instruct (Q8_0). Larger models need CPU/GPU offload.
Can the RTX A6000 run a 70B model?
Compatible: a 70B model at Q4_K_M needs about 45.1 GB; the RTX A6000 has 48 GB.
How is the speed estimated?
Token generation reads every active weight once per token, so it is limited by memory bandwidth (768 GB/s here). We apply an efficiency range per backend and label the result as an estimate until real benchmarks exist.
