Performance Analysis
H100 PCIe dominates in precision performance: its 1979 TFLOPS FP16 capability dwarfs TITAN Xp's 12.1 TFLOPS, slashing training times for deep learning models that leverage half-precision arithmetic. FP32 throughput of 67 TFLOPS on H100 exceeds TITAN Xp's 12.1 TFLOPS, benefiting single-precision scientific simulations and graphics rendering. The FP16 to FP32 delta on H100 enables efficient mixed-precision training, reducing memory usage while maintaining accuracy, unlike TITAN Xp's balanced but limited 12.1 TFLOPS across both.
Memory specs transform real-world usability: 80 GB HBM3 VRAM on H100 supports batch sizes for massive LLMs that 12 GB GDDR5X on TITAN Xp cannot handle, preventing out-of-memory errors. Bandwidth of 3350 GB/s versus 548 GB/s ensures H100 processes data flows 6 times faster, critical for inference latency and large-dataset training. TITAN Xp's 250W TDP allows air-cooled consumer builds, but H100's 700W demands datacenter cooling, trading efficiency for raw scale.
