Can the Radeon RX 9070 run Qwen3 235B-A22B?
Does not fit at Q4_K_M.
Qwen3 235B-A22B is 235B parameters (MoE; all experts resident). At Q4_K_M the weights are about 131.3 GiB; with the 1.5 GiB runtime reserve that is 132.8 GiB against the card's 16GB, about 116.8 GiB more than the card has.

Verdict rules: fits comfortably when weights plus reserve sit within 85% of VRAM; tight when they fit with little left for context; CPU offload when they exceed VRAM by up to 2x (runs, slowly, with layers in system RAM); no beyond that. The KV cache per token depends on the model's architecture and is not modelled here.
The numbers for this pairing
At Q4_K_M the weights take about 131.3 GiB, so with the 1.5 GiB runtime reserve it needs 132.8 GB: 116.8 GB more than the card's 16 GB.
No version of it fits entirely in this card's memory, so it would lean on system RAM and run far slower.
It is a mixture-of-experts model: about 22B of its 235B parameters work on each token, which helps speed, but all of them still have to fit in memory.
At about $570, this card costs roughly $36 per GB of VRAM.
Running it at its full 220 W board power for 4 hours a day would use about 26 kWh a month, about $4.86 at the US average residential rate of 18.4 cents per kWh (2026-05); real use sits below that ceiling.
Prices are the lowest current listings our tracker saw on Oct 7, 2026, since averages include premium variants; launch prices are marked where we have no listing.
Not this card. These fit it comfortably at Q4.
Nothing in the consumer catalog fits Qwen3 235B-A22B at Q4 on a single card; this is multi-GPU or datacenter territory, or a job for hosted inference (see PicksByModel for per-token pricing).
