Performance Analysis
The A40 supplies dense FP16 performance at 149.7 TFLOPS while the RTX 5000 Ada does not publish an FP16 figure. The A40 also supplies FP32 performance at 37.4 TFLOPS compared with 65.3 TFLOPS on the RTX 5000 Ada. Higher memory bandwidth of 696 GB per second on the A40 versus 576 GB per second on the RTX 5000 Ada supports larger batch sizes during training and inference. The A40 dense FP16 figure exceeds its own FP32 figure by a factor of four while the RTX 5000 Ada provides no comparable dense FP16 value for direct ratio analysis.
