Performance Analysis

The FP16 dense figure of 165 TFLOPS on the A30 versus the FP16 dense figure of 1307.4 TFLOPS on the MI300X produces an eightfold difference that shortens training iteration times for large models. The FP16 with sparsity figure of 330 TFLOPS on the A30 versus the FP16 with sparsity figure of 2614.9 TFLOPS on the MI300X yields a similar eightfold gap that benefits inference throughput when sparsity patterns are present. Memory bandwidth of 933 GB/s on the A30 versus 5300 GB/s on the MI300X limits sustainable batch sizes on the former while the latter supports eight times the VRAM capacity for larger context windows.

When to Choose the A30

The A30 suits deployments that prioritize 165W TDP over higher throughput. Organizations running FP32 workloads at 10.3 TFLOPS or INT8 dense workloads at 330 TOPS select the A30 when PCIe form factor and NVLink interconnect fit existing server layouts.

When to Choose the MI300X

The MI300X suits workloads that require 192 GB HBM3 capacity and 5300 GB/s bandwidth. Teams executing FP16 dense operations at 1307.4 TFLOPS or FP8 dense operations at 2614.9 TFLOPS choose the MI300X when OAM form factor and Infinity Fabric interconnect align with scale-out clusters.

How this page is made

  • Specifications come from the NVIDIA, AMD and Intel datasheets for the A30 and the MI300X. 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.
