Intel Sapphire Rapids will appear in next-generation DGX H100 AI systems with NVIDIA H100 GPUs. At the BofA Securities 2022 Global Technology Conference event, NVIDIA founder Jensen Huang confirmed that the x86 processor in the next-generation DGX H100 AI system will be replaced by Intel’s 4th generation Xeon Scalable processor Sapphire Rapids. The original DGX system used AMD Zen 3 architecture EPYC processors.
The reason for switching from AMD EPYC to Intel Sapphire Rapids, Jensen Huang also mentioned in the meeting. The main reason for changing the processor is that the single-core performance of Intel Sapphire Rapids is higher than that of its rival, the Genoa of AMD’s Zen 4 architecture.
For the Zen 4 architecture Genoa, AMD has not yet had any information updates, maybe we can expect more information from AMD at the investor conference on June 10.
In fact, there is not much information about Intel Sapphire Rapids. The most basic thing is that it supports DDR5 memory, integrates HBM2E, and provides next-generation technologies such as PCIe Gen5 and CXL 1.1; the processor core part, the same as Alder Lake, is the Golden Cove processor architecture.
