Performance Analysis
The FP32 performance difference shows the RTX 4000 Ada at 26.7 TFLOPS exceeding the RTX A4000 at 19.2 TFLOPS for dense operations that support both training and inference tasks. Memory bandwidth at 448 GB/s on the RTX A4000 versus 360 GB/s on the RTX 4000 Ada allows larger batch sizes in memory intensive workloads on the former card. The RTX A4000 lists FP16 performance at 153.4 TFLOPS with sparsity while the RTX 4000 Ada lists FP8 performance at 427.6 TFLOPS with sparsity so like for like tensor comparisons remain limited to the published dense FP32 figures.
