NVIDIA’s GH200 is a powerful combination of the 72-core Grace CPU and the H100 Tensor Core GPU.
It supports up to 480GB of LPDDR5 memory and either 96GB of HBM3 or 144GB of HBM3e memory.
The NVIDIA GH200 runs standard AArch64 Linux distributions.
All server processors tested were running at their top-rated memory frequencies and maximum number of memory channels supported.
The initial benchmarks focused on CPU performance, with GPU benchmarks to follow.
The Arm Neoverse-V2 based Grace CPU tended to be much faster than the 128-core Ampere Altra Max AArch64 server.
It will be interesting to see how AmpereOne can compete albeit no hardware available yet for testing.
(Unfortunately no AMD MI300A hardware either for testing right now.)
More of the CPU benchmark numbers are available viathis result file.
There’s also some other benchmarksherefrom some of the preliminary testing.
