H200 vs Quadro P4000

The H200 delivers FP16 dense performance of 989 TFLOPS while the Quadro P4000 lists no FP16 figure from the vendor so no direct ratio applies. The FP32 value of 67 TFLOPS on the H200 exceeds the 5.3 TFLOPS on the Quadro P4000 by a factor derived solely from those two numbers. Memory bandwidth of 4800 GB/s on the H200 versus 243 GB/s on the Quadro P4000 permits substantially larger batch sizes during operations that move large tensors because the bandwidth ratio reaches nearly twenty times in favor of the H200. The H200 FP16 with sparsity reaches 1979 TFLOPS and FP8 dense reaches 1979 TFLOPS allowing direct like for like comparison only within the H200 specifications themselves.

The H200 suits workloads that require 141 GB VRAM and 4800 GB/s bandwidth such as large model training or inference where the 989 TFLOPS FP16 dense rating accelerates tensor operations beyond the capabilities of older cards. Its support for NVLink and InfiniBand interconnects further enables multi GPU scaling that the Quadro P4000 PCIe 3.0 interface cannot match.

The Quadro P4000 fits environments constrained to 105W TDP and PCIe form factors where basic FP32 workloads at 5.3 TFLOPS suffice without need for high bandwidth or large memory capacity. Legacy systems already equipped with Pascal architecture cards avoid migration costs when only modest compute demands exist.
