What is the NVIDIA A10?

The A10 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. A10 full specifications →

Can I rent the A10 in the cloud?

Yes. Cloud providers tracked by Flopper rent the A10 by the hour, and the pricing page compares their current rates and the price history side by side. A10 rental prices →

How does the A10 compare with other accelerators?

This page sets the A10 against the A100. The A10 is the newer generation of the two. Both are NVIDIA parts, and both ship as a PCIe card, so they fit the same class of system. The compare tool builds the same comparison for any two parts in the catalogue. All GPU comparisons →

FLOPS by Precision

What actually differs

The A10 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 600 GB/s against 1.6 TB/s, which sets the ceiling on decode speed.

Power is 150 W against 250 W, and at FP32 the A10 does more work per watt. Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.

Frequently asked questions

Is the A10 faster than the A100?

At FP16 precision the A100 reaches 312 TFLOPS dense against 125 TFLOPS for the A10. The performance table on this page lists every published precision for both GPUs.

Which should you choose, the A10 or the A100?

Choose the A100 for training and high-throughput inference: it has 2.5x the FP16 throughput of the A10. It also carries 16 GB more memory, so larger models fit on one GPU before you shard. The A100 draws 100 W more power, so budget for cooling and power delivery before you commit.

Which has more memory, the A10 or the A100?

The A100 carries 40 GB of memory versus 24 GB for the A10. Memory bandwidth is 600 GB/s for the A10 and 1.6 TB/s for the A100.

How much power do the A10 and the A100 draw?

The A10 is rated at 150 W TDP and the A100 at 250 W. On FP32 throughput per watt, the A10 is the more efficient part.

How much do the A10 and the A100 cost to rent?

Live cloud listings tracked by Flopper price the A10 from $1.10 per GPU-hour across 4 providers, and the A100 from $0.45 per GPU-hour across 1 provider. The rental section on this page links to every provider, rate and the price history for each GPU.
