H200 vs RTX A4000

The FP16 dense figure of 989 TFLOPS on the H200 exceeds the FP16 with sparsity figure of 153.4 TFLOPS on the RTX A4000 by a factor of six when comparing the published tensor metrics directly. This gap implies substantially higher throughput for training and inference operations that rely on dense FP16 calculations on the H200. The FP32 performance ratio stands at 67 TFLOPS to 19.2 TFLOPS which favors the H200 by approximately three and a half times for precision sensitive tasks. Memory bandwidth of 4800 GB/s on the H200 compared with 448 GB/s on the RTX A4000 allows larger batch sizes during model execution because data movement occurs at over ten times the rate. The H200 sparsity figures reach 1979 TFLOPS FP16 with sparsity while the RTX A4000 remains at 153.4 TFLOPS FP16 with sparsity so the H200 maintains a clear advantage in sparse workloads as well.

The H200 suits scenarios that require 141 GB HBM3e VRAM and 4800 GB/s bandwidth for handling extensive datasets. The 700W TDP and SXM form factor align with installations that prioritize maximum tensor throughput.

The RTX A4000 fits environments constrained to 140W TDP and PCIe form factors. Applications that operate within 16 to 20 GB GDDR6 VRAM and 448 GB/s bandwidth choose the RTX A4000 for its lower power draw and simpler interconnect requirements. The 19.2 TFLOPS FP32 performance meets needs where compact deployment takes precedence over peak tensor rates.
