Performance Analysis
The difference in FP16 dense performance between 2250 TFLOPS on the GB300 and 364 TFLOPS on the RTX 6000 Ada indicates that the GB300 can process larger batches during training and inference operations. Memory bandwidth at 8000 GB/s versus 960 GB/s allows the GB300 to handle increased data movement which supports bigger batch sizes in model execution. FP32 performance stands at 75 TFLOPS for the GB300 compared to 91.1 TFLOPS for the RTX 6000 Ada showing that certain scientific workloads may favor the RTX 6000 Ada in single precision tasks. Comparisons of sparse figures such as FP16 with sparsity at 4500 TFLOPS versus 728 TFLOPS maintain the same relative advantage for the GB300.
