When to Choose the A100
The A100 suits workloads that operate within 40 to 80 GB of HBM2e memory and require 400W TDP. Organizations running established pipelines on Ampere architecture avoid migration costs when the 312 TFLOPS dense FP16 performance meets throughput targets. The 2039 GB/s memory bandwidth remains adequate for moderate batch sizes in inference scenarios.
When to Choose the B200
The B200 suits workloads that require 180 to 192 GB of HBM3e memory and deliver 2250 TFLOPS dense FP16 performance. Organizations scaling to larger models benefit from the 8000 GB/s memory bandwidth that accommodates bigger batch sizes. The 1000W TDP supports sustained operation in dense FP16 and dense FP8 configurations where the 4500 TFLOPS dense FP8 figure accelerates inference.
Use Cases
The B200 provides 2250 TFLOPS dense FP16 and 8000 GB/s memory bandwidth that exceed A100 figures.
The B200 provides 4500 TFLOPS dense FP8 that exceed A100 dense FP16 figures for throughput.
The B200 provides 180 to 192 GB memory capacity that supports larger fine-tuning batches than the A100.
The A100 provides 312 TFLOPS dense FP16 at 400W TDP that meets requirements without excess power draw.
The A100 provides 19.5 TFLOPS FP32 at 400W TDP that suits established scientific workloads.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the A100 and the B200. Dense and sparse throughput are listed separately.
- Prices and availability are live: every offer shown is an in-stock, on-demand listing from a provider we track, rechecked every minute.
- The written comparison (overview, performance notes, when to choose each card, verdict, use cases and FAQ) was drafted with an AI model from the specification table above and passed an automated check that rejects any figure not in that table. It was last generated on . It contains no prices; those are always read live.
