Can I Run Command R+ (104B) on NVIDIA GeForce RTX 4070 Ti Super?
作者： Jakub Rusinowski · 最后更新： 2026年9月19日
No. Command R+ (104B) needs 62.8 GB at Q4_K_M and the NVIDIA GeForce RTX 4070 Ti Super has only 16 GB. No quantization we publish closes a gap that size.

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 16 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 4070 Ti Super: 8K 65.7 GB ✗ · 32K 72.2 GB ✗ · 125K 97.1 GB ✗. Past 8K it no longer fits 16 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Either step down to a smaller size in this family, or move to a Apple M1 Max (64 GB), the cheapest card we track with enough VRAM.
No compatible GPU? Command R+ (104B) on 256 GB of system RAM, CPU only: runs, but too slowly to be worth it.
