Can I Run Qwen 2.5 7B Instruct on Intel Arc B580?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 12 lipca 2026
Yes. Qwen 2.5 7B Instruct needs 5.9 GB at 8K context (4.6 GB weights + 1.3 GB KV cache/overhead) at Q4_K_M and the Intel Arc B580 has 12 GB, leaving about 6.1 GB of headroom, at roughly 46 tok/s (estimated) with room for up to 64K of context.

Qwen 2.5 7B Instruct on the Intel Arc B580: VRAM by quantization

| Q2_K | 3.8 GB | ✓ Yes | 128K | — |
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 5.9 GB · 32K 7.3 GB · 128K 12.9 GB ✗. Past 128K 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
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
