Performance Analysis
The A30 delivers 165 TFLOPS dense FP16 while the RTX A4000 lists only 153.4 TFLOPS FP16 with sparsity, so direct dense to dense comparison uses the A30 figure alone. Sparse FP16 on the A30 reaches 330 TFLOPS against 153.4 TFLOPS with sparsity on the RTX A4000. FP32 performance measures 10.3 TFLOPS on the A30 versus 19.2 TFLOPS on the RTX A4000. The 933 GB/s bandwidth on the A30 versus 448 GB/s on the RTX A4000 allows larger batch sizes in memory bound workloads. INT8 dense performance on the A30 reaches 330 TOPS and 661 TOPS with sparsity.

When to Choose the A30
The A30 suits workloads that require 24 GB HBM2 memory and 933 GB/s bandwidth together with NVLink connectivity. Its 165 TFLOPS dense FP16 and 330 TOPS dense INT8 support large batch inference and training jobs that benefit from the higher memory capacity over the RTX A4000.
When to Choose the RTX A4000
The RTX A4000 fits FP32 centric tasks that use its 19.2 TFLOPS FP32 rating and 140W TDP. Its PCIe form factor without NVLink matches single card deployments where the 16 to 20 GB GDDR6 memory suffices.
Use Cases
The A30 supplies 24 GB HBM2 memory and 933 GB/s bandwidth that support larger models than the RTX A4000 16 to 20 GB GDDR6 memory.
The A30 330 TOPS INT8 with sparsity and 24 GB memory enable higher throughput inference compared to the RTX A4000.
The A30 165 TFLOPS dense FP16 combined with NVLink allows efficient fine tuning on larger batches than the RTX A4000.
The RTX A4000 19.2 TFLOPS FP32 rating suits diffusion workloads that rely on single precision performance.
The RTX A4000 19.2 TFLOPS FP32 and 140W TDP fit scientific codes that prioritize FP32 throughput in lower power envelopes.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the A30 and the RTX A4000. 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.
