A Xeon from the Sapphire Rapids family shows up

This leak in the form of a stolen photo allows us to understand a part of the design of an Intel Xeon processor of the family Sapphire Rapids. Indeed, as can be clearly seen, two elements can be distinguished as if two CPU had been assembled. On the IHS, this is even more obvious. Each element of this Xeon could then integrate up to 28 hearts . We therefore look like a top model with 56 cores and 112 threads. Xeon Sapphire Rapids

Xeon Sapphire Rapids: 400W despite the 10nm!

As a reminder, this generation of Xeon benefits from a 10nm +++ manufacturing process (not 10nm SuperFin). Despite this, this 56-core model should have a consumption of up to 400W. The socket for this CPU is the LGA4677.

On-chip HBM2e memory

The chips would also incorporate four HBM2e memory stacks, where each stack can hold up to 16 GB of memory. This means that up to 64 GB of HBM2e memory could be mounted with a bandwidth of up to 1 TB/s. Interestingly, these Xeons will be the first Intel platform to use the PCI-Express 5.0 interface with up to 80 lines in high-end processors and 64 lines in other lighter models. Also in the hood is the use of a 4800 MHz DDR5 memory controller with Intel Data Streaming Accelerator (DSA) technology. Xeon Sapphire Rapids A lot of new assets for these Xeons if we consider the current AMD competitor, the Milan from Zen 3, engraved in 7nm and still running in DDR4 and with PCIE 4.0. However, the AMD EPYC GENES should soon arrive in Zen4 engraved in 5 nm. They too will have PCIe 5.0 and DDR5… Xeon Sapphire Rapids roadmap
