H100 PCIe: specs and benchmarks
Summary
NVIDIA started H100 PCIe sales 22 March 2022. This is a Hopper architecture desktop card based on 4 nm manufacturing process and primarily aimed at designers. 80 GB of HBM2e memory clocked at 1 GHz are supplied, and together with 5120 Bit memory interface this creates a bandwidth of 1,280 GB/s.
Compatibility-wise, this is a dual-slot graphics card attached via PCIe 5.0 x16 interface. Its manufacturer default version has a length of 267 mm. 8-pin EPS power connector is required, and power consumption is at 350 Watt.
