Intel released the third-generation expandable Xeon code-named Ice Lake-SP last month. The 10nm process was introduced for the first time. The number of cores increased from 28 to 40, but compared to AMD’s second and third-generation EPYC 64, there is still a great distance.
According to previous reports, the fourth-generation Xeon, code-named Sapphire Rapids, has no more than 60 cores, and actually only opens 56, which is still out of rivals. Is it true that Intel really intends to give up on the number of cores?
Recently, some netizens shared the latest photos of Sapphire Rapids. It is still composed of four internal chiplet integrated packages, and each small chip contains up to 20 cores, and the 4×5 layout is clearly visible. The number of cores is 80, corresponding to 160 threads.
According to the information currently available, Sapphire Rapids will be manufactured using a 10nm SuperFin enhanced process. It will first support DDR5 memory, up to eight channels, 4800MHz, and integrate HBM2 high-bandwidth memory for the first time, up to 64GB, and support next-generation Optane persistent memory. Random access bandwidth is increased by up to 2.6 times.
In terms of technology, the first release supports PCIe 5.0 with a maximum of 80 channels. The multi-channel interconnection channel is upgraded to four UPI 2.0, each with a bandwidth of 16GT/s. It also supports CXL 1.1 high-speed interconnection bus. It also supports CXL 1.1 high-speed interconnect bus, and can also be connected to an independent FPGA accelerator through PCIe 5.0 and CXL. The instruction set supports INT8, BFloat16 precision AMX, TMIUL. The power consumption is also quite amazing, the TDP upper limit has been increased from 270W to 350W.
