It’s been a while since YuuKi_AnS has been leaking Sapphire Rapids (aka Intel 4th Gen Core Xeon Scalable) details. He was the first one to share photos of the new CPU along with a video.
Once YuuKi_AnS successfully removed the heat spreader and sanded the CPU, he then captured the first photos of Sapphire Rapids’ die. The CPU houses 4 compute dies where each die has 15 cores however the final product will not have 60 cores. A complex design of this level requires a few cores to be disabled for good yields and availability even for the top Sapphire Rapids SKU. As per leaked information, the 4th Gen Xeon will have a maximum of 56 cores. This means that at least four cores will be nonfunctional on the whole CPU package.
Yuuki has also shared the specifications of the pictured CPU sample. The sample operates on a QVV5 code (early ES0 sample and the frequency is locked at 1.3 GHz. It will also have up to 64GB of HBM2e memory which Intel recently confirmed through its Linux kernel update.
Intel’s Sapphire Rapids architecture will be a game-changer for Intel in the high-performance HPC market. The series will offer a higher core count, onboard HBM2e memory with PCIe Gen5 interface, and DDR5 memory support. The last two are the major upgrades over Intel’s latest Ice Lake-SP series.
Intel’s latest interface standards, and high-speed memory, and their 10nm Enhanced SuperFin architecture will surely give a tough time to AMD’s EPYC 7003 “Milan” series based on Zen3 architecture.
