DeepSeek 7B on RTX 3090: Monthly Cost & Token Output
Dedicated RTX 3090 hosting for DeepSeek 7B (7B) inference — fixed monthly pricing with unlimited tokens.
100 Tokens per Second for £89
The RTX 3090 hits the sweet spot for DeepSeek 7B inference: 100 tok/s throughput, 24 GB VRAM (17 GB free after loading the model), and a price tag that keeps monthly costs under £90. Over 30 days, that adds up to roughly 259 million tokens.
| Metric | Value |
|---|---|
| GPU | RTX 3090 (24 GB VRAM) |
| Model | DeepSeek 7B (7B parameters) |
| Monthly Server Cost | £89/mo |
| Tokens/Second | ~100.0 tok/s |
| Tokens/Day (24h) | ~8,640,000 |
| Tokens/Month | ~259,200,000 |
| Effective Cost per 1M Tokens | £0.3434 |
How the Numbers Compare
DeepSeek 7B is available through several API providers. Here is the per-token cost comparison when running at capacity on dedicated hardware:
| Provider | Cost per 1M Tokens | GigaGPU Savings |
|---|---|---|
| GigaGPU (RTX 3090) | £0.3434 | — |
| Together.ai | $0.20 | Comparable |
| Fireworks | $0.20 | Comparable |
| DeepInfra | $0.13 | Comparable |
API providers look cheap in the table, but their costs scale with every request. Your £89 GigaGPU bill stays the same whether utilisation is 5% or 100%.
Break-Even Threshold
Against DeepInfra’s $0.13/1M rate, the break-even is approximately 684.6M tokens/month. Beyond that volume, dedicated hardware delivers pure savings with every token.
With the RTX 3090’s 17 GB of free VRAM enabling aggressive batching through vLLM, real-world throughput under concurrent load can significantly exceed the 100 tok/s baseline. Use the cost calculator to model your actual workload.
Why the 3090 Works Well Here
- Ample headroom: 7 GB for the model, 17 GB remaining for KV cache and batching — enough to handle dozens of concurrent users.
- Quantisation optional: INT8/INT4 can push throughput to 130+ tok/s, but FP16 runs comfortably with room to spare.
- Drop-in serving: vLLM and TGI provide OpenAI-compatible endpoints for seamless migration from API providers.
- Easy expansion: Stack additional 3090 servers behind a load balancer when throughput demands increase.
Recommended Workloads
- Production chatbots with consistent daily traffic
- Document summarisation and extraction at scale
- RAG systems backed by multi-user GPU serving
- Coding assistants for development teams
- Nightly batch analysis of text datasets
