FLOPS by Precision

What actually differs

The RTX A2000 is the newer part: Ampere (2021) against the A100's Ampere (2020).

The A100 carries 74 GB more memory (80 GB against 6 GB), so larger models fit on one GPU before you shard. Bandwidth is 2.0 TB/s against 288 GB/s, which sets the ceiling on decode speed.

Power is 400 W against 70 W, and at FP32 the RTX A2000 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 A100 faster than the RTX A2000?

At FP32 precision the A100 reaches 20 TFLOPS dense against 8 TFLOPS for the RTX A2000. The performance table on this page lists every published precision for both GPUs.

Which should you choose, the A100 or the RTX A2000?

Choose the A100 for training and high-throughput inference: it has 2.4x the FP32 throughput of the RTX A2000. It also carries 74 GB more memory, so larger models fit on one GPU before you shard. The A100 draws 330 W more power, so budget for cooling and power delivery before you commit. Packaging differs too: the A100 is an SXM module while the RTX A2000 is a PCIe card, so check what your servers accept.

Which has more memory, the A100 or the RTX A2000?

The A100 carries 80 GB of memory versus 6 GB for the RTX A2000. Memory bandwidth is 2.0 TB/s for the A100 and 288 GB/s for the RTX A2000.

How much power do the A100 and the RTX A2000 draw?

The A100 is rated at 400 W TDP and the RTX A2000 at 70 W. On FP32 throughput per watt, the RTX A2000 is the more efficient part.

How much do the A100 and the RTX A2000 cost to rent?

Live cloud listings tracked by Flopper price the A100 from $0.56 per GPU-hour across 27 providers, and no live listings yet for the RTX A2000. The rental section on this page links to every provider, rate and the price history for each GPU.
