Up to 80 cores for Intel Sapphire Rapids processors?

Up to 80 cores for Intel Sapphire Rapids processors?

We know that the 4th generation Intel Xeon processors, Sapphire Rapids, will be etched with a 10 nm SuperFin manufacturing process. Until now, a maximum configuration of 56 cores and 128 threads with a TDP of 350W was mentioned. However, recently some photographs of the die reveal that these processors made with the technique known as “chiplet”, could embark up to a total of 80 cores with no less than 64 GB of integrated HBM2 memory.


This hypothesis is taken from a photo of a supposed Intel Sapphire Rapids with 4 large Dies that could each receive 20 cores, thus reaching a total of 80 cores. So far only a 56-core model had been spotted and seemed to use a configuration with 14-core dies.

It is YuuKi_AnS, known for various leaks, which has published these images to advance these elements.

If this hypothesis is true, this family of Xeon could be a more serious opposition to the AMD EPYC GENOA CPUs which will have a maximum configuration with 96 cores and 192 threads with theZen4 architecture engraved in 5nm.

The Sapphire Rapids Xeons promise a 50% improvement in IPC compared to Skylake. They will support 4800 MHz DDR5 RAM in an Octa (8)-Channel configuration with up to 80 PCI-Express 5.0 lanes. Given the timetable and production capacity restrictions, it is not impossible that these Intel processors will be on the market before AMD’s solution.
