OpenRadioss benchmark with settings of Model: Bird Strike on Windshield. Xeon Max 9468 2P: HBM Only was the fastest.

OpenRadioss benchmark with settings of Model: INIVOL and Fluid Structure Interaction Drop Container. Xeon Max 9468 2P: HBM Only was the fastest.

OpenRadioss as the open-source software based on Altair Radioss was showing some decent time savings with the Xeon Max HBM-only mode.

Quantum ESPRESSO benchmark with settings of Input: AUSURF112. Xeon Max 9468 2P: HBM Only was the fastest.

The Quantum Espresso software also was enjoying the HBM2E on Sapphire Rapids. In some workloads the Xeon Max 9468 was ahead of the Xeon Max 9480 where the workloads don't scale as well or when the greater amount of HBM2e per core was more favorable with the Xeon Max 9468.

RELION benchmark with settings of Test: Basic, Device: CPU. Xeon Max 9468 2P: HBM Only was the fastest.

SPECFEM3D benchmark with settings of Model: Water-layered Halfspace. Xeon Max 9480 2P: HBM Only was the fastest.

For many HPC workloads there was significant uplift from operating the Xeon Max 9468 and 9480 processors in HBM-only mode. But, of course, keep in mind the main limitation around having just 64GB of system memory addressable per socket when running in HBM-only mode for these initial Xeon Max processors. For workloads needing more memory -- or threaded workloads liking well more than 1GB per core -- it can mean resource contention / out-of-memory behavior.
