In addition to the Core processor roadmap and CPU process roadmap, Intel also announced the Xeon Xeon processor roadmap at the investor conference today, will launch the Saphire Rapids processor in March this year, and will introduce energy efficiency cores to the Xeon product line for the first time in 2024.
In 2021 and before, Intel's Xeon processor is the IceLake-SP series of 10nm process, and the Sapphire Rapids processor will be delivered in the first quarter of this year, using intel 7 process, that is, the same 12th generation Core, and the kernel architecture is the same Golden Cove.
According to Intel, sapphire Rapids processors will dramatically improve performance for a wide range of workloads, achieving up to 30x performance gains in AI alone.
In addition, the Sapphire Rapids processor will also have a version with integrated HBM2e memory, with a capacity of up to 64GB, and the memory bandwidth is 4 times higher than that of DDR memory, which greatly improves performance.
Intel also announced the performance test of the HBM version of the Sapphire Rapids processor, compared to the OpenFOAM Benchmark test, with the current 3rd generation Xeon ICL as the benchmark, the Sapphire Rapids processor itself performance is 1.6x, sapphire Rapids + HBM reached 2.8x, but also than AMD's milan-X, that is, the 3D V-Cache version of Zen3 EPYC's 1.3x performance is more than doubled.
After the Sapphire Rapids processor, Intel will have a major change in the Xeon processor architecture, the first time to introduce the design of performance core, energy efficiency core, and based on this implementation of a dual-track roadmap, the simple understanding is that the future Xeon processor is some for high performance, some are for high density, more focus on performance per watt.
The first Xeon to adopt a performance core architecture is Sierra Forest, a leading product based on Intel's 3-process process with high density and ultra-high energy efficiency, and will be launched in 2024.
Granite Rapids, which has been exposed before, will be the next generation of the performance core architecture, originally scheduled to use the Intel 4 process, but Intel is very confident in the Intel 3 process, so Granite Rapids is also directly on the Intel 3 process, which is also launched in 2024.
Intel 3 process after the Xeon processor has no clear codename, from Intel's roadmap, 20A process does not have a new Xeon, in the second half of 2024 18A process there will be a new generation Xeon, the details have not been announced.
