Can I Run Granite 4.1 3B on Intel Arc B570?
Written by Jakub Rusinowski · Last updated July 12, 2026
Yes. Granite 4.1 3B needs 3.5 GB at 8K context (1.8 GB weights + 1.7 GB KV cache/overhead) at Q4_K_M and the Intel Arc B570 has 10 GB, leaving about 6.5 GB of headroom, at roughly 73 tok/s (estimated) with room for up to 64K of context.

Granite 4.1 3B on the Intel Arc B570: VRAM by quantization

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 3.5 GB · 32K 6 GB · 128K 16 GB ✗. Past 128K 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
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
