Performance Analysis

The A16 records dense FP16 at 17.9 TFLOPS and FP16 with sparsity at 35.9 TFLOPS. The RTX A4000 records FP16 with sparsity at 153.4 TFLOPS. The FP32 figure of 4.5 TFLOPS on the A16 versus 19.2 TFLOPS on the RTX A4000 indicates that the RTX A4000 processes general matrix operations more than four times faster. Memory bandwidth of 200 GB/s on the A16 versus 448 GB/s on the RTX A4000 limits batch sizes during data intensive steps on the A16 relative to the RTX A4000.
