Intel has revealed new benchmarks of its upcoming data center products including the HBM-Supercharged Sapphire Rapids-SP Xeon CPUs.

In the performance slide shown by Intel, the company compares its upcoming Sapphire Rapids-SP Xeon CPUs with HBM to its older Ice Lake Xeon Scalable chips and AMD's EPYC Milan/Milan-X CPUs. The workload used here was the OpenFOAM benchmark, specifically the Computational Fluid Dynamics test. Intel states that this benchmark was running on a pre-production Sapphire Rapids chip so final performance numbers may vary.
