BGE-M3 (embed, 1024-dim) on H100 SXM5 80GB: Does It Fit, How Fast, What It Costs

BGE-M3 (embed, 1024-dim) at FP16 needs 1.1 GB for its weights and 7.6 GB in total at 8K context with 8 concurrent users. That means it fits on a single H100 SXM5 80GB. Every figure is computed by tokcalc's open-source capacity model.

Frequently asked questions

Can BGE-M3 (embed, 1024-dim) run on H100 SXM5 80GB?

Yes. BGE-M3 (embed, 1024-dim) at FP16 needs 7.6 GB including the KV cache, and H100 SXM5 80GB has 80 GB — so it fits on a single GPU.

How fast is BGE-M3 (embed, 1024-dim) on H100 SXM5 80GB?

1917 tokens/sec per stream and 23002 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 49.3 ms, and inter-token latency is 521.7 µs.

What does BGE-M3 (embed, 1024-dim) on H100 SXM5 80GB cost per million tokens?

$0.0302 per 1M output tokens at 1× H100 SXM5 80GB ($2.50/hr). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.

How much VRAM does BGE-M3 (embed, 1024-dim) need on H100 SXM5 80GB?

1.1 GB for the weights at FP16, plus 6.4 GB of KV cache for 8 concurrent requests at 8K context — 7.6 GB total. Every extra concurrent user at long context costs more, so leave headroom.

Is H100 SXM5 80GB the right choice for BGE-M3 (embed, 1024-dim)?

It works. Compare $0.0302 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 1× RTX 3080 10GB at $0.0106, and the fastest is 1× Cerebras CS-3 (WSE-3) at 137324 tok/s.
