Can I Run IBM Granite 4.1 on AMD Radeon RX 9060 XT 8GB?
Written by Jakub Rusinowski · Last updated July 12, 2026
Yes, comfortably — Granite 4.1 8B at Q4_K_M needs 6.8 GB at 8K context (4.8 GB weights + 2 GB KV cache/overhead), leaving ~1.2 GB of the AMD Radeon RX 9060 XT 8GB's 8 GB, at ~36 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 8 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 AMD Radeon RX 9060 XT 8GB: 8K 6.8 GB · 32K 10.2 GB ✗ · 128K 23.9 GB ✗. Past 32K it no longer fits 8 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? Granite 4.1 8B on 16 GB of system RAM, CPU only: runs.
