Performance Analysis

The FP16 dense performance of 112.6 TFLOPS on the RTX 5080 exceeds the FP32 figure of 56.3 TFLOPS by a factor of two. This ratio supports accelerated training and inference in mixed precision setups. The RTX A4000 provides FP16 performance with sparsity at 153.4 TFLOPS against its FP32 value of 19.2 TFLOPS. Memory bandwidth at 960 GB/s on the RTX 5080 compared to 448 GB/s on the RTX A4000 allows larger batch sizes in memory bound operations. Sparse FP16 performance reaches 225.1 TFLOPS on the RTX 5080 while the RTX A4000 lists 153.4 TFLOPS with sparsity. These figures indicate the RTX 5080 handles higher throughput in sparse tensor computations.
