Performance Analysis
The FP16 dense performance of the A30 reaches 165 TFLOPS while the H100 reaches 989 TFLOPS dense so the H100 delivers substantially higher throughput for mixed precision workloads. FP32 figures show the A30 at 10.3 TFLOPS against the H100 at 67 TFLOPS which widens the gap for single precision scientific kernels. Memory bandwidth of 933 GB/s on the A30 versus 3350 GB/s on the H100 directly limits sustainable batch sizes on the older card during large model inference. When sparsity is enabled the A30 FP16 figure rises to 330 TFLOPS while the H100 reaches 1979 TFLOPS with sparsity so relative ordering remains unchanged across dense and sparse modes.

When to Choose the A30
The A30 suits deployments where 24 GB HBM2 memory meets workload demands and power draw must stay at 165 W TDP. PCIe only form factor and PCIe 4.0 interconnect further align the A30 with existing server infrastructures that lack SXM5 or InfiniBand support.
When to Choose the H100
The H100 fits workloads that require 80 to 94 GB HBM3 capacity together with 3350 GB/s bandwidth for large batch training. FP16 dense throughput of 989 TFLOPS and FP32 throughput of 67 TFLOPS accelerate both training and inference relative to the A30 while NVLink and PCIe 5.0 options enable tighter multi GPU scaling.
Use Cases
The H100 supplies 989 TFLOPS FP16 dense and 80 to 94 GB memory which exceed the A30 165 TFLOPS and 24 GB limits.
The H100 provides 3350 GB/s bandwidth and 1979 TFLOPS FP16 with sparsity enabling larger batches than the A30 933 GB/s and 330 TFLOPS with sparsity.
FP32 performance of 67 TFLOPS on the H100 surpasses the A30 10.3 TFLOPS while 80 to 94 GB memory accommodates adapter layers.
The A30 24 GB memory suffices for many diffusion resolutions at 165 W TDP yet the H100 3350 GB/s bandwidth accelerates higher resolution generation.
The H100 FP32 rating of 67 TFLOPS and 3350 GB/s bandwidth outperform the A30 10.3 TFLOPS and 933 GB/s for simulation workloads.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the A30 and the H100. 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.
