Although not widely available yet, AMD’s EPYC Milan-X server processors equipped with 3D V-Cache memory created great excitement. Intel, on the other hand, claims to take the lead with HBM2E memory.
How is Intel Sapphire Rapids performance?
Sapphire Rapids processors, which come with scaling up to 56 cores and a total cache of up to 100MB, aim to block AMD. This is also the case with benchmark tests.
Sapphire Rapids-based Xeon processors have 64GB HBM2E on-chip memory. According to Raja Khoduri, its integration into the package provides large GPU-like memory bandwidths in processor loads and can make up to 4x the difference.
Sapphire Rapids processor with 64GB HBM2E memory can reach 1.22TB/s bandwidth. There is an increase of up to 4 times compared to the DDR5-4800 Sapphire Rapids processor.
On the other hand, according to OpenFOAM Motorbike 28M tests focusing on memory loads, there is a 180 percent increase compared to standard Ice Lake-SP processors. Again, AMD Milan and especially Milan-X processors lag far behind in this test. Moreover, the EPYC Milan-X processor also achieved an improvement of only about 30 percent compared to the previous generation, contrary to AMD’s statements.
The processor models on which the tests were conducted are not disclosed and there is no verification by independent authorities. Because in other tests, AMD seemed ahead. Still, Intel is quite hopeful of its new processors.
