Can I Run Cosmos 3 Edge on Intel Arc B570?
Written by Jakub Rusinowski · Last updated July 21, 2026
Yes, but it's tight. Cosmos 3 Edge needs 9.7 GB at 8K context (8 GB weights + 1.7 GB KV cache/overhead) at BF16 and the Intel Arc B570 has 10 GB, leaving about 0.3 GB of headroom, at roughly 42 tok/s (estimated).

Cosmos 3 Edge 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 BF16 on the Intel Arc B570: 8K 9.7 GB · 16K 10.6 GB ✗. Past 16K 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 BF16. If you want more capability, check whether the next size up also fits.
