## What fits in VRAM: 16 GB vs 24 GB

| Workload | Tesla V100 | RTX 3090 |
| --- | --- | --- |
| Largest LLM in FP16, one card | ~3B | ~8B |
| Largest LLM at 4-bit, one card | ~24B | ~32B |
| Flux dev (FP8, ~17 GB) | tight | fits |
| Wan 2.x 14B video (offloaded) | no | yes |
| 70B 4-bit LLM on one card | no | no |

Rules of thumb: ~2.4 GB per billion parameters in FP16 all-in, ~0.62 GB in 4-bit. Full tables in the [VRAM guide](https://powergpu.ai/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:** RTX 3090 ($0.108 vs $0.130, −17%).
- **More VRAM:** RTX 3090 (24 GB vs 16 GB).
- **More FP16 throughput:** RTX 3090 (about 1.1×).
- **Best value per TFLOP-hour:** RTX 3090.
- **Best value per GB of VRAM:** RTX 3090.
- **Multi-GPU:** Tesla V100 over PCIe · RTX 3090 over PCIe.

**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 RTX 3090: $0.108/hr on-demand versus $0.130/hr — 17% less. Interruptible rates are $0.065 (Tesla V100) and $0.054 (RTX 3090). 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 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 PowerGPU right now?**

Yes — 96 × Tesla V100 and 345 × RTX 3090 are online as this page renders, deployable in about 30 seconds, billed per second, paid in crypto with no KYC.
