Can I Run Qwen 3 32B on AMD Radeon RX 9070?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 12 lipca 2026
Not at Q4_K_M — that needs 22.8 GB at 8K context and the AMD Radeon RX 9070 has 16 GB. Drop to Q2_K and it fits in 13.7 GB, with up to 16K of context.

Qwen 3 32B on the AMD Radeon RX 9070: VRAM by quantization

Assumes an 8K-token context with an f16 KV cache. 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 9070: 8K 22.8 GB ✗ · 32K 29.2 GB ✗ · 125K 54.2 GB ✗. Past 8K it no longer fits 16 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Quantize to Q2_K. That is the cheapest fix — it costs some quality but no money.
