Performance Analysis
The H200 dominates in FP16 performance at 1979 TFLOPS compared to the RTX 4090's 165 TFLOPS, accelerating AI training where half-precision computations prevail and enabling faster convergence on large datasets. For inference, the H200's 3958 TFLOPS FP8 throughput vastly outpaces the RTX 4090's 660 TFLOPS, supporting higher query volumes in production environments. However, the RTX 4090 leads in FP32 at 82.6 TFLOPS over the H200's 67 TFLOPS, benefiting simulations or rendering that demand single-precision accuracy.
Memory specifications define real-world usability: the H200's 141 GB HBM3e allows batch sizes for models exceeding 100 billion parameters without swapping, while the RTX 4090's 24 GB GDDR6X limits it to smaller batches or models under 30 billion parameters. The 4800 GB/s bandwidth on the H200 sustains data flow for these scales, reducing bottlenecks versus the RTX 4090's 1008 GB/s. Higher TDP of 700W on the H200 reflects its density, contrasting the 450W RTX 4090 suited for lighter power envelopes.
