Can RTX 6000 Ada 48GB run DeepSeek-R1-0528-Qwen3-8B?
NVIDIA · 48 GB GDDR6 · 960 GB/s bandwidth ·
DeepSeek · 8.2B · model ctx up to 128K
Yes — the RTX 6000 Ada 48GB (48 GB GDDR6) can run DeepSeek-R1-0528-Qwen3-8B. At Q4 with the default 8K context it needs ≈ 7.15 GB VRAM (weights 4.51 GB + KV cache 1.64 GB + 1 GB runtime overhead), which fits within 48 GB. Decode at Q4/8K: ≈ 74.5 tok/s (estimated, batch 1). FP16 (≈ 19.04 GB) also fits, at ≈ 20.5 tok/s (estimated). Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s.

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).
