Can I Run Granite 4.1 8B on AMD Radeon RX 9060 XT 8GB?
Written by Jakub Rusinowski · Last updated July 12, 2026
Yes. Granite 4.1 8B needs 6.8 GB at 8K context (4.8 GB weights + 2 GB KV cache/overhead) at Q4_K_M and the AMD Radeon RX 9060 XT 8GB has 8 GB, leaving about 1.2 GB of headroom, at roughly 36 tok/s (estimated) with room for up to 16K of 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.
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.
