Performance Analysis
The A40 delivers FP16 dense performance of 149.7 TFLOPS against the Quadro RTX 8000 FP16 dense performance of 130.5 TFLOPS, producing a ratio of 149.7 to 130.5. This difference translates into faster matrix operations during training and inference workloads that rely on dense FP16 computation. The A40 FP32 figure of 37.4 TFLOPS compared with 16.3 TFLOPS likewise supports larger batch sizes when memory bandwidth of 696 GB/s exceeds 672 GB/s. When sparsity is enabled the A40 reaches FP16 with sparsity of 299.4 TFLOPS while the Quadro RTX 8000 figure remains unavailable for direct comparison.

When to Choose the A40
The A40 suits workloads that require the higher FP32 performance of 37.4 TFLOPS and the denser INT8 dense rating of 299.3 TOPS. Its 696 GB/s memory bandwidth further supports larger batch processing than the 672 GB/s alternative in sustained Ampere based pipelines.
When to Choose the Quadro RTX 8000
The Quadro RTX 8000 fits environments constrained by the 260W TDP limit where the 300W rating of the A40 exceeds power budgets. Its Turing architecture still supplies 48 GB GDDR6 memory and 130.5 TFLOPS dense FP16 for lighter inference tasks.
Use Cases
The A40 supplies 149.7 TFLOPS dense FP16 and 37.4 TFLOPS FP32 which exceed the Quadro RTX 8000 values of 130.5 TFLOPS and 16.3 TFLOPS.
The A40 INT8 dense rating of 299.3 TOPS combined with 696 GB/s bandwidth enables larger batch inference than the Quadro RTX 8000 specifications allow.
FP16 dense performance of 149.7 TFLOPS on the A40 supports fine-tuning throughput beyond the 130.5 TFLOPS dense FP16 of the Quadro RTX 8000.
Both GPUs provide 48 GB GDDR6 memory so either card handles diffusion workloads with the A40 offering higher 149.7 TFLOPS dense FP16.
The A40 FP32 rating of 37.4 TFLOPS surpasses the 16.3 TFLOPS of the Quadro RTX 8000 for compute intensive scientific kernels.
