Multilingual E5 Large (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 A100 80GB SXM4. Every figure is computed by tokcalc's open-source capacity model.

Yes. Multilingual E5 Large (1024-dim) at FP16 needs 7.6 GB including the KV cache, and A100 80GB SXM4 has 80 GB — so it fits on a single GPU.
1161 tokens/sec per stream and 13929 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 89.7 ms, and inter-token latency is 861.5 µs.
$0.0239 per 1M output tokens at 1× A100 80GB SXM4 ($1.20/hr). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.
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.
It works. Compare $0.0239 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 1× RTX 3080 10GB at $0.0105, and the fastest is 1× Cerebras CS-3 (WSE-3) at 139286 tok/s.
