Can I Run Command R Family on NVIDIA RTX 6000 Ada Generation?
Written by Jakub Rusinowski · Last updated July 21, 2026
Yes, comfortably — Command R (35B) at Q4_K_M needs 32.7 GB at 8K context (21.1 GB weights + 11.6 GB KV cache/overhead), leaving ~15.3 GB of the NVIDIA RTX 6000 Ada Generation's 48 GB, at ~31 tok/s (est.), with room for up to 16K context.

Assumes an 8K-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 48 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 RTX 6000 Ada Generation: 8K 32.7 GB · 32K 64.9 GB ✗ · 125K 189.7 GB ✗. Past 32K it no longer fits 48 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.
