Can I Run LFM2.5 on Intel Arc B570?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 15 października 2026
Yes, comfortably — LFM2.5-8B-A1B at Q4_K_M needs 7 GB at 8K context (5 GB weights + 2 GB KV cache/overhead), leaving ~3 GB of the Intel Arc B570's 10 GB, at ~95 tok/s (est.), with room for up to 16K context.

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 7 GB · 32K 10.5 GB ✗ · 128K 24.6 GB ✗. Past 32K it no longer fits 10 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? LFM2.5-8B-A1B on 16 GB of system RAM, CPU only: runs.
