H800 SXM5: specs and benchmarks
Summary
NVIDIA started H800 SXM5 sales 21 March 2023. This is a desktop graphics card based on a Hopper architecture and made with 4 nm manufacturing process. It is primarily aimed at gamer market. 80 GB of HBM3 memory clocked at 2.6 GB/s are supplied, and together with 5120 Bit memory interface this creates a bandwidth of 1,681 GB/s.
Compatibility-wise, this is sxm module card attached via PCIe 5.0 x16 interface. 8-pin EPS power connector is required, and power consumption is at 700 Watt.
