Not at Q4_K_M — that needs 21.1 GB and the AMD Radeon RX 7900 XT has 20 GB. Drop to Q3_K_M and it fits in 17.6 GB, with up to 8K of context.

Assumes a 4K-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 20 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 7900 XT: 8K 23.8 GB ✗ · 32K 29.4 GB ✗ · 128K 52 GB ✗. Past 8K it no longer fits 20 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
Quantize to Q3_K_M. That is the cheapest fix — it costs some quality but no money.
No compatible GPU? Qwen 3.6 35B-A3B on 32 GB of system RAM, CPU only: runs, but it is tight.
