Qwen 3 4B at FP16 needs 8.0 GB for its weights and 17.7 GB in total at 8K context with 8 concurrent users. That means it fits on a single Intel Gaudi 3 128GB. Every figure is computed by tokcalc's open-source capacity model.

Yes. Qwen 3 4B at FP16 needs 17.7 GB including the KV cache, and Intel Gaudi 3 128GB has 128 GB — so it fits on a single GPU.
268.1 tokens/sec per stream and 3218 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 105.2 ms, and inter-token latency is 3.7 ms.
$0.1727 per 1M output tokens at 1× Intel Gaudi 3 128GB ($2.00/hr). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.
8.0 GB for the weights at FP16, plus 9.7 GB of KV cache for 8 concurrent requests at 8K context — 17.7 GB total. Every extra concurrent user at long context costs more, so leave headroom.
It works. Compare $0.1727 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 2× RTX 3080 10GB at $0.0441, and the fastest is 1× Cerebras CS-3 (WSE-3) at 19500 tok/s.
