NVIDIA H200 SXM (141 GB)

The NVIDIA H200 SXM (141 GB) is a workstation graphics card that launched in Q4 2024. It is built on the Hopper GPU microarchitecture (codename GH100) and is manufactured on a 5 nm process.

Memory

The H200 SXM has 141 GB of HBM3e memory, with a 1,593 MHz memory clock and a 6,144 bit interface. This gives it a memory bandwidth of 4.89 Tb/s, which affects how fast it can transfer data to and from memory. GPU memory stores temporary data that helps the GPU with complex math and graphics operations. More memory is generally better, as not having enough can cause performance bottlenecks.

Cores and Clock Speeds

The H200 SXM includes 16,896 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,500 MHz and can dynamically boost its clock speed up to 1,980 MHz. Complementing the processing units are 528 texture mapping units (TMUs) for efficient texture filtering and 24 render output units (ROPs) for pixel processing. Additionally, the GPU features 528 tensor cores optimized for AI-accelerated workloads.

Compatibility & Power Consumption

NVIDIA recommends a power supply of at least 1,100 W to handle the GPU's thermal design power (TDP) of 700 W.
