Frequently asked questions

Can NVIDIA RTX 3080 Ti run Qwen3 235B-A22B?

No. Even at Q4_K_M, Qwen3 235B-A22B needs about 144.7 GB, but the NVIDIA RTX 3080 Ti has 12 GB usable. You could offload some layers to system RAM, but it will be very slow.

How much VRAM does Qwen3 235B-A22B need?

About 144.7 GB at Q4_K_M with 8,192 tokens of context, and about 472.4 GB at full FP16 precision.

How fast is Qwen3 235B-A22B on the NVIDIA RTX 3080 Ti?

It does not fit in the NVIDIA RTX 3080 Ti's memory, so most layers would run from system RAM and generation would be very slow.
