DeepSeek Coder V2 236B (MoE) at AWQ 4-bit needs 129.8 GB for its weights and 142.4 GB in total at 8K context with 8 concurrent users. That means it fits on a single AMD MI300X 192GB. Every figure is computed by tokcalc's open-source capacity model.

Yes. DeepSeek Coder V2 236B (MoE) at AWQ 4-bit needs 142.4 GB including the KV cache, and AMD MI300X 192GB has 192 GB — so it fits on a single GPU.
262.5 tokens/sec per stream and 3150 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 560.3 ms, and inter-token latency is 3.8 ms.
$0.2205 per 1M output tokens at 1× AMD MI300X 192GB ($2.50/hr). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.
129.8 GB for the weights at AWQ 4-bit, plus 12.6 GB of KV cache for 8 concurrent requests at 8K context — 142.4 GB total. Every extra concurrent user at long context costs more, so leave headroom.
It works. Compare $0.2205 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 8× RTX 5090 32GB at $0.0192, and the fastest is 4× Cerebras CS-3 (WSE-3) at 161646 tok/s.
