What is the NVIDIA A100?

The A100 is a GPU from NVIDIA on the Ampere architecture, an accelerator for AI training, inference and high-performance computing. It is a PCIe add-in card, so it fits standard servers and workstations. A100 full specifications →

Can I rent the A100 in the cloud?

Yes. Cloud providers tracked by Flopper rent the A100 by the hour, and the pricing page compares their current rates and the price history side by side. A100 rental prices →

How does the A100 compare with other accelerators?

This page sets the A100 against the A30. The A100 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 A100 SXM4 80GB, across every published precision, memory and power. A100 vs A100 SXM4 80GB →

FLOPS by Precision

What actually differs

The A30 is the newer part: Ampere (2021) against the A100's Ampere (2020).

The A100 carries 16 GB more memory (40 GB against 24 GB), so larger models fit on one GPU before you shard. Bandwidth is 1.6 TB/s against 933 GB/s, which sets the ceiling on decode speed.

Power is 250 W against 165 W, and at FP32 the A100 does more work per watt. Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.
