Frequently asked questions

Can BGE-M3 (embed, 1024-dim) run on RTX A4000 16GB?

Yes. BGE-M3 (embed, 1024-dim) at FP16 needs 7.6 GB including the KV cache, and RTX A4000 16GB has 16 GB — so it fits on a single GPU.

How fast is BGE-M3 (embed, 1024-dim) on RTX A4000 16GB?

256.3 tokens/sec per stream and 3076 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 988.4 ms, and inter-token latency is 3.9 ms.

What does BGE-M3 (embed, 1024-dim) on RTX A4000 16GB cost per million tokens?

$0.0271 per 1M output tokens at 1× RTX A4000 16GB ($0.3000/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 RTX A4000 16GB?

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 RTX A4000 16GB the right choice for BGE-M3 (embed, 1024-dim)?

It works. Compare $0.0271 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.
