Can I Run Qwen 3.5 2B on NVIDIA RTX PRO 6000 Blackwell?
Written by Jakub Rusinowski · Last updated July 21, 2026
Yes. Qwen 3.5 2B needs 2.7 GB at 8K context (1.2 GB weights + 1.5 GB KV cache/overhead) at Q4_K_M and the NVIDIA RTX PRO 6000 Blackwell has 96 GB, leaving about 93.3 GB of headroom, at roughly 305 tok/s (estimated) with room for up to 32K of context.

Assumes an 8K-token context with an f16 KV cache, on an estimated architecture — this model publishes no config we can read. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 96 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 PRO 6000 Blackwell: 8K 2.7 GB · 32K 5 GB. Every window this model publishes still fits 96 GB.
What to do next
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
