Why it matters

H200 addresses memory bottleneck of H100. Understanding shapes hardware selection.

The architecture

SM count: same as H100.

HBM3e: 141GB, 4.8 TB/s.

Same TDP as H100.

How it works end to end

Same PCIe / NVLink as H100.

Drop-in replacement.

~1.5-2x inference throughput on memory-bound workloads.
