Performance Analysis
The FP16 dense figure of 17.9 TFLOPS on the A16 versus 97.5 TFLOPS on the RTX 4080 indicates that the RTX 4080 completes dense FP16 operations more than five times faster for training and inference steps. The FP16 with sparsity figure of 35.9 TFLOPS on the A16 versus 195 TFLOPS on the RTX 4080 maintains the same ratio when sparsity is applied. Memory bandwidth of 200 GB/s on the A16 compared with 717 GB/s on the RTX 4080 limits batch sizes in memory bound kernels on the A16 while the RTX 4080 sustains larger batches. FP32 throughput of 4.5 TFLOPS on the A16 versus 48.7 TFLOPS on the RTX 4080 further widens the gap for workloads that fall back to single precision.
