Command R (35B) on the NVIDIA GeForce RTX 3060 (12GB): VRAM by quantization

Assumes a 4K-token context with an f16 KV cache. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 12 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the NVIDIA GeForce RTX 3060 (12GB): 8K 32.7 GB ✗ · 32K 64.9 GB ✗ · 125K 189.7 GB ✗. Past 8K it no longer fits 12 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? Command R Family on 256 GB of system RAM, CPU only: runs, but too slowly to be worth it.
