Can I Run IBM Granite 4.0 on Intel Arc B580?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 15 sierpnia 2026
No — Granite 4.0 Small-H 32B-A9B at Q4_K_M needs 22 GB at 8K context (19.3 GB weights + 2.7 GB KV cache/overhead), and the Intel Arc B580's 12 GB leaves it ~10 GB short. The cheapest card that runs it is the NVIDIA GeForce RTX 5090 Laptop GPU (24 GB).

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 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 22 GB ✗ · 32K 27.5 GB ✗ · 128K 49.6 GB ✗. Past 8K it no longer fits 12 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? Granite 4.0 Small-H 32B-A9B on 24 GB of system RAM, CPU only: runs.
Why It Does Not Fit
Every IBM Granite 4.0 variant requires more VRAM than the Intel Arc B580 provides (12 GB).
Nearest GPU That Fits
