Qwen 2.5-VL 7B (VLM) on RTX 6000 Ada 48GB: Does It Fit, How Fast, What It Costs

Qwen 2.5-VL 7B (VLM) at FP16 needs 14.0 GB for its weights and 17.8 GB in total at 8K context with 8 concurrent users. That means it fits on a single RTX 6000 Ada 48GB. Every figure is computed by tokcalc's open-source capacity model.

What changes as you add RTX 6000 Ada 48GBs
Tensor-parallel degree vs VRAM, throughput, and cost. Cost scales linearly with GPU count; decode throughput scales near-linearly too, so cost per token stays roughly flat.

Frequently asked questions

Can Qwen 2.5-VL 7B (VLM) run on RTX 6000 Ada 48GB?

Yes. Qwen 2.5-VL 7B (VLM) at FP16 needs 17.8 GB including the KV cache, and RTX 6000 Ada 48GB has 48 GB — so it fits on a single GPU.

How fast is Qwen 2.5-VL 7B (VLM) on RTX 6000 Ada 48GB?

44.57 tokens/sec per stream and 534.9 tok/s aggregate with continuous batching at 8 concurrent users. Time to first token is 2.56 s, and inter-token latency is 22.4 ms.

What does Qwen 2.5-VL 7B (VLM) on RTX 6000 Ada 48GB cost per million tokens?

$0.4155 per 1M output tokens at 1× RTX 6000 Ada 48GB ($0.8000/hr). That is the marginal hardware cost — add idle capacity, ops, and egress for the real figure.

How much VRAM does Qwen 2.5-VL 7B (VLM) need on RTX 6000 Ada 48GB?

14.0 GB for the weights at FP16, plus 3.8 GB of KV cache for 8 concurrent requests at 8K context — 17.8 GB total. Every extra concurrent user at long context costs more, so leave headroom.

Is RTX 6000 Ada 48GB the right choice for Qwen 2.5-VL 7B (VLM)?

It works. Compare $0.4155 per 1M tokens against the alternatives below — the cheapest option that fits the same workload is 2× RTX 3080 10GB at $0.0772, and the fastest is 1× Cerebras CS-3 (WSE-3) at 11143 tok/s.
