Full tables in the [VRAM guide](https://lowcostgpu.com/guides/llm-vram-requirements). ## Verdict: which should you rent? The V100 offers 16 GB HBM2, real FP64 and datacenter design; the RTX 3090 has 24 GB and roughly the same FP16 tensor throughput at a lower rate. Rent the V100 for double precision, the 3090 for ML with more memory. - **Cheaper per hour:** Tesla V100 ($0.093 vs $0.148, −37%). - **More VRAM:** RTX 3090 (24 GB vs 16 GB). - **More FP16 throughput:** RTX 3090 (about 1.1×). - **Best value per TFLOP-hour:** Tesla V100. - **Best value per GB of VRAM:** Tesla V100. - **Multi-GPU:** Tesla V100 over PCIe · RTX 3090 over PCIe. ## Related comparisons [All comparisons](https://lowcostgpu.com/compare) - [RTX 4090 vs RTX 3090 $0.354 vs $0.148 per hour](https://lowcostgpu.com/compare/rtx-4090-vs-rtx-3090) - [RTX 3090 vs RTX 3060 $0.148 vs $0.058 per hour](https://lowcostgpu.com/compare/rtx-3090-vs-rtx-3060) ## Tesla V100 vs RTX 3090: FAQ Deeper reading: [H100 vs H200 vs B200](https://lowcostgpu.com/guides/h100-vs-h200-vs-b200), [RTX 4090 vs RTX 5090](https://lowcostgpu.com/guides/rtx-4090-vs-rtx-5090), [how cloud GPU pricing works](https://lowcostgpu.com/guides/cloud-gpu-pricing-explained). **Is the RTX 3090 faster than the Tesla V100?** On dense FP16 tensor throughput the RTX 3090 leads by about 1.1× (142 vs 125 TFLOPS). Memory bandwidth matters as much for inference: Tesla V100 900 GB/s vs RTX 3090 936 GB/s. **Which is cheaper to rent, the Tesla V100 or the RTX 3090?** The Tesla V100: $0.093/hr on-demand versus $0.148/hr — 37% less. Interruptible rates are $0.046 (Tesla V100) and $0.074 (RTX 3090). Per TFLOP-hour the better value is the Tesla V100. **Which has more VRAM and what does that change?** The RTX 3090 has 24 GB versus 16 GB. In LLM terms that is roughly a 8B FP16 model (or ~32B in 4-bit) on one card against 3B FP16 (~24B 4-bit). If the model does not fit, speed is irrelevant. **Can I rent both on LowCostGPU right now?** Yes — 120 × Tesla V100 and 293 × RTX 3090 are online as this page renders, deployable in about 30 seconds, billed per second, paid in crypto with no KYC. --- *About LowCostGPU:* LowCostGPU (lowcostgpu.com) is a cloud GPU rental service offering 83 NVIDIA GPU models — from the Tesla P4 at $0.019/hr to the B300 — at fixed prices set at least 30% below the public GPU marketplace median and re-checked weekly (H100 SXM: $1.680/hr on-demand).
