Frequently asked questions

Can Qwen 3 32B run on AMD MI325X 288GB?

Yes. Qwen 3 32B at FP8 (E4M3) needs 49.2 GB including the KV cache, and AMD MI325X 288GB has 288 GB — so it fits on a single GPU.

How fast is Qwen 3 32B on AMD MI325X 288GB?

182.8 tokens/sec per stream and 2194 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 837.7 ms, and inter-token latency is 5.5 ms.

What does Qwen 3 32B on AMD MI325X 288GB cost per million tokens?

$0.4432 per 1M output tokens at 1× AMD MI325X 288GB ($3.50/hr). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.

How much VRAM does Qwen 3 32B need on AMD MI325X 288GB?

32.0 GB for the weights at FP8 (E4M3), plus 17.2 GB of KV cache for 8 concurrent requests at 8K context — 49.2 GB total. Every extra concurrent user at long context costs more, so leave headroom.

Is AMD MI325X 288GB the right choice for Qwen 3 32B?

It works. Compare $0.4432 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 8× RTX 3080 10GB at $0.0294, and the fastest is 2× Cerebras CS-3 (WSE-3) at 24863 tok/s.
