Full tables in the [VRAM guide](https://powergpu.ai/guides/llm-vram-requirements). ## Verdict: which should you rent? Both Ampere: the 3090 has 24 GB and about 2.8× the throughput of the 12 GB 3060. The 3060 is the cheapest way to run 7B–8B 4-bit models and SD 1.5; the 3090 opens 13B FP16, SDXL batches and LoRA training. - **Cheaper per hour:** RTX 3060 ($0.042 vs $0.108, −61%). - **More VRAM:** RTX 3090 (24 GB vs 12 GB). - **More FP16 throughput:** RTX 3090 (about 2.8×). - **Best value per TFLOP-hour:** RTX 3090. - **Best value per GB of VRAM:** RTX 3060. - **Multi-GPU:** RTX 3090 over PCIe · RTX 3060 over PCIe. ## Related comparisons [All comparisons](https://powergpu.ai/compare) - [RTX 4090 vs RTX 3090 $0.327 vs $0.108 per hour](https://powergpu.ai/compare/rtx-4090-vs-rtx-3090) - [Tesla V100 vs RTX 3090 $0.130 vs $0.108 per hour](https://powergpu.ai/compare/tesla-v100-vs-rtx-3090) ## RTX 3090 vs RTX 3060: FAQ Deeper reading: [H100 vs H200 vs B200](https://powergpu.ai/guides/h100-vs-h200-vs-b200), [RTX 4090 vs RTX 5090](https://powergpu.ai/guides/rtx-4090-vs-rtx-5090), [how cloud GPU pricing works](https://powergpu.ai/guides/cloud-gpu-pricing-explained). **Is the RTX 3090 faster than the RTX 3060?** On dense FP16 tensor throughput the RTX 3090 leads by about 2.8× (142 vs 51 TFLOPS). Memory bandwidth matters as much for inference: RTX 3090 936 GB/s vs RTX 3060 360 GB/s. **Which is cheaper to rent, the RTX 3090 or the RTX 3060?** The RTX 3060: $0.042/hr on-demand versus $0.108/hr — 61% less. Interruptible rates are $0.054 (RTX 3090) and $0.021 (RTX 3060). Per TFLOP-hour the better value is the RTX 3090. **Which has more VRAM and what does that change?** The RTX 3090 has 24 GB versus 12 GB. In LLM terms that is roughly a 8B FP16 model (or ~32B in 4-bit) on one card against 3B FP16 (~14B 4-bit). If the model does not fit, speed is irrelevant. **Can I rent both on PowerGPU right now?** Yes — 345 × RTX 3090 and 279 × RTX 3060 are online as this page renders, deployable in about 30 seconds, billed per second, paid in crypto with no KYC. --- *About PowerGPU:* PowerGPU (powergpu.ai) is a cloud GPU rental service offering 80 NVIDIA GPU models — from the RTX A2000 at $0.024/hr to the B300 — at fixed prices set at least 30% below the public GPU marketplace median and re-checked weekly (H100 SXM: $1.428/hr on-demand).
