A100 vs A16

The FP16 dense rating of 312 TFLOPS on the A100 exceeds the 17.9 TFLOPS rating on the A16 by a factor derived directly from those two numbers. The same pattern holds for FP16 with sparsity where 624 TFLOPS stands against 35.9 TFLOPS. FP32 performance follows a similar ratio with 19.5 TFLOPS compared to 4.5 TFLOPS. Memory bandwidth of 2039 GB/s versus 200 GB/s determines the maximum sustainable batch size during both training and inference passes. INT8 dense throughput of 624 TOPS on the A100 versus 35.9 TOPS on the A16 produces corresponding differences in quantized inference throughput. All comparisons maintain separation between dense and sparsity labeled figures.

The A100 suits large scale training workloads that require the 40 GB to 80 GB memory capacity and 2039 GB/s bandwidth. Its FP16 dense rating of 312 TFLOPS supports models whose working sets exceed the 16 GB limit of the alternative device.

The A16 fits inference tasks where the 250 W TDP and 16 GB GDDR6 configuration meet throughput targets without exceeding power or slot constraints. Its PCIe form factor and 4.5 TFLOPS FP32 rating align with lighter workloads that do not require HBM2e capacity.
