Can I Run Qwen 3.6 35B-A3B on Intel Arc B580?
Written by Jakub Rusinowski · Last updated July 12, 2026
No. Qwen 3.6 35B-A3B needs 22.1 GB at 8K context (21.1 GB weights + 1 GB KV cache/overhead) at Q4_K_M and the Intel Arc B580 has only 12 GB. No quantization we publish closes a gap that size.

Qwen 3.6 35B-A3B on the Intel Arc B580: VRAM by quantization

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 12 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 Intel Arc B580: 8K 22.1 GB ✗ · 32K 22.6 GB ✗ · 128K 24.6 GB ✗. Past 8K it no longer fits 12 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 NVIDIA GeForce RTX 5090 Laptop GPU (24 GB), the card with the least memory we track that holds it.
