Intel Sapphire Rapids, new photos of the die reveal the number of cores?

Intel Sapphire Rapids

According to some photos recently published on the net, Intel's Sapphire Rapids CPUs could contain about 72-80 cores, a considerably higher number than initially estimated.

The well-known leaker YuuKi_AnS has released some photos relating to the Sapphire chiplets Rapids. This time he removed the dies from the substrate, exposing the other side. Much to the surprise, this revealed a 4 × 5 group of similar elements believed to be Sapphire Rapids' CPU cores. Considering that each chiplet contains 20 dies, the high-end Sapphire Rapids processors could go up to 80 cores, while the cheaper ones, of course, will have less.

As for the TDP, there was talk of 350W for the 56-core model. The engineering sample featured in these photos is exactly the same CPU that was first pictured in February, more than three months ago, so it's the same one obtained from an Intel partner in early 2021 or late 2020.

According to rumors, Intel has provided Sapphire Rapids samples with 28 cores enabled and many believed that the company had activated only half of the cores that its chiplet physically possessed (ie 7 out of 14). While, apparently, the CPU will have 20 cores per chiplet, which theoretically allows Intel to build processors with up to 80 cores. In addition, 56-core CPUs will have six redundant cores per chiplet, which is far too many. Conversely, two redundant cores per chiplet would allow for 72-core CPUs.

Intel's new Sapphire Rapids CPU: PCIe 5.0 tech, 64GB of HBM2e memory

We are finding out some more information on Intel's next-gen Sapphire Rapids architecture, with the next-gen Xeon platform set to pack some juicy specs and technologies when it drops.


The new tease is from VideoCardz with an anonymous tipster sending a slide that shows the specifications of Intel's upcoming Sapphire Rapids platform. We're looking at up to 56 cores per CPU, DDR5 memory support, 64GB of HBM2e memory per socket (!!!), PCIe 5.0 support with up to 80 lanes of PCIe 5.0 goodness, and so much more.

Sapphire Rapids will scale between 1 and 8 sockets, so you will be able to cram in many of those 56-core CPUs into future supercomputers. But the most surprising things here are the 80 PCIe 5.0 lanes and 64GB of HBM2e memory on-package with up to 1TB/sec of memory bandwidth per socket. Delicious.

Intel's next-gen Sapphire Rapids has been teased in a 24-core model with a 225W TDP, a 44-core model at 270W, and the flagship 56-core model with up to 350W. We will see Intel's new Sapphire Rapids CPUs powering the new Aurora Supercomputer at Argonne National Laboratory.
