Can I Run Qwen 3.5 27B on Intel Arc B570?
作者： Jakub Rusinowski · 最后更新： 2026年7月12日
No. Qwen 3.5 27B needs 18.8 GB at 8K context (16.3 GB weights + 2.5 GB KV cache/overhead) at Q4_K_M and the Intel Arc B570 has only 10 GB. No quantization we publish closes a gap that size.

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 10 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 B570: 8K 18.8 GB ✗ · 32K 24.1 GB ✗ · 128K 45 GB ✗. Past 8K it no longer fits 10 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 AMD Radeon RX 7900 XT (20 GB), the card with the least memory we track that holds it.
No compatible GPU? Qwen 3.5 27B on 24 GB of system RAM, CPU only: runs comfortably.
Cheapest card we track with enough VRAM for Qwen 3.5 27B:
Qwen 3.5 27B needs ~19 GB but this GPU has 10 GB. Rent a RTX 4090 (24 GB)-class GPU by the hour instead of buying one:
