A16 vs Quadro P4000

The A16 provides FP16 dense performance at 17.9 TFLOPS while the Quadro P4000 lists no FP16 figure from the vendor. This delta means the A16 supports FP16 dense workloads such as certain inference tasks at a measurable rate where the Quadro P4000 cannot be directly compared on that metric. FP32 figures show the Quadro P4000 at 5.3 TFLOPS against 4.5 TFLOPS dense on the A16. Memory bandwidth of 243 GB per second on the Quadro P4000 exceeds the 200 GB per second on the A16 and may allow modestly larger batch sizes in memory bound FP32 operations. The A16 further lists INT8 dense at 35.9 TOPS and INT8 with sparsity at 71.8 TOPS with no corresponding figures published for the Quadro P4000.

The A16 suits workloads that require 16 GB VRAM and FP16 dense throughput of 17.9 TFLOPS. Its PCIe 4.0 interconnect and Ampere architecture support higher precision tensor operations including INT8 dense at 35.9 TOPS in scenarios where the Quadro P4000 lacks published equivalents.

The Quadro P4000 fits environments constrained to 105 W TDP and FP32 performance at 5.3 TFLOPS. Its 243 GB per second memory bandwidth provides an advantage in select FP32 tasks despite the lower 8 GB VRAM capacity compared to the A16.
