Can I rent the GeForce RTX 4090 in the cloud?

Yes. Cloud providers tracked by Flopper rent the GeForce RTX 4090 by the hour, and the pricing page compares their current rates and the price history side by side. GeForce RTX 4090 rental prices →

How does the GeForce RTX 4090 compare with other accelerators?

This page sets the GeForce RTX 4090 against the RTX 6000 Ada. The GeForce RTX 4090 is the older generation of the two. Both are NVIDIA parts, and both ship as a PCIe card, so they fit the same class of system. Flopper also compares it head to head with the Wormhole n150s, across every published precision, memory and power. GeForce RTX 4090 vs Wormhole n150s →

Where do the GeForce RTX 4090 figures come from?

NVIDIA published the GeForce RTX 4090 figures in marketing material rather than a datasheet, and Flopper has no independent confirmation of them. How Flopper verifies specifications →

FLOPS by Precision

What actually differs

The RTX 6000 Ada is the newer part: Ada Lovelace (2023) against the GeForce RTX 4090's Ada Lovelace (2022).

The RTX 6000 Ada carries 24 GB more memory (48 GB against 24 GB), so larger models fit on one GPU before you shard. Bandwidth is 1.0 TB/s against 960 GB/s, which sets the ceiling on decode speed.

Power is 450 W against 300 W, and at FP32 the RTX 6000 Ada does more work per watt. Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.
