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 RTX 4090 24GB. 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 RTX 4090 24GB has 24 GB — so it fits on a single GPU.
585.0 tokens/sec per stream and 7020 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 253.9 ms, and inter-token latency is 1.7 ms.
$0.0158 per 1M output tokens at 1× RTX 4090 24GB ($0.4000/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 $0.0158 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.
