Can I Run InternLM 3 on AMD Radeon RX 9060 XT 16GB?
Written by Jakub Rusinowski · Last updated July 12, 2026
Yes, but it's tight — InternLM 3 20B Instruct at Q4_K_M needs 14.5 GB at 8K context (12.1 GB weights + 2.4 GB KV cache/overhead), leaving ~1.5 GB of the AMD Radeon RX 9060 XT 16GB's 16 GB, at ~16 tok/s (est.), with room for up to 8K 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 16 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 16GB: 8K 14.5 GB · 32K 19.2 GB ✗. Past 32K it no longer fits 16 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
