Can RTX 3090 24GB run DeepSeek-R1-Distill-Llama-70B?
NVIDIA · 24 GB GDDR6X · 936 GB/s bandwidth ·
DeepSeek · 70.6B · model ctx up to 128K
No — DeepSeek-R1-Distill-Llama-70B at Q4 needs ≈ 46.89 GB even at 4K context, beyond the RTX 3090 24GB's 24 GB GDDR6X. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 4.8 tok/s (estimated, batch 1). FP16 needs ≈ 156.32 GB — does not fit on this card. Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s. Methodology.

Fits = weights + KV(ctx) + 1 GB overhead ≤ 95% of VRAM. Measured
anchors are context-agnostic; the fit verdict is recomputed per context. A missing tok/s
means the model is far beyond this card (offload-only territory).
