Performance Analysis
The A30 delivers 165 TFLOPS FP16 dense compared with 149.7 TFLOPS FP16 dense on the A40 while the A30 also reaches 330 TFLOPS FP16 with sparsity compared with 299.4 TFLOPS FP16 with sparsity on the A40. This FP16 dense advantage of 165 TFLOPS over 149.7 TFLOPS supports faster matrix operations in inference whereas the A40 FP32 figure of 37.4 TFLOPS exceeds the A30 value of 10.3 TFLOPS by more than three times and favors precision sensitive training steps.

When to Choose the A30
The A30 suits deployments that prioritize lower TDP at 165 W together with higher memory bandwidth at 933 GB/s and stronger FP16 dense performance at 165 TFLOPS. Scenarios that run continuous inference benefit from these attributes because they reduce power draw while sustaining higher throughput on dense FP16 workloads than the 149.7 TFLOPS dense figure available on the alternative.
When to Choose the A40
The A40 suits deployments that require greater memory capacity at 48 GB along with higher FP32 throughput at 37.4 TFLOPS. Workloads that load large models or execute floating point heavy scientific calculations gain from these specifications even though TDP rises to 300 W and bandwidth falls to 696 GB/s.
Use Cases
The A40 supplies 48 GB memory capacity and 37.4 TFLOPS FP32 that accommodate larger model states during training passes.
The A30 supplies 165 TFLOPS FP16 dense and 933 GB/s bandwidth that sustain higher throughput at lower 165 W TDP.
Both GPUs offer comparable INT8 dense ratings near 300 TOPS and NVLink support that handle fine tuning steps at similar scale.
The A40 supplies 48 GB memory that holds larger diffusion model weights and intermediate activations during generation.
The A40 supplies 37.4 TFLOPS FP32 that accelerate double precision calculations beyond the 10.3 TFLOPS available on the A30.

How this page is made
- Specifications come from the NVIDIA, AMD and Intel datasheets for the A30 and the A40. 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.
