Intel: Xeon Sapphire Rapids will have 56 cores for 350W

Several months ago, we told you about a leak complete on the next range of servers from Intel. Today it’s the turn of a relatively complete “official” slide to appear on the net.

Sapphire Rapids

Sapphire Rapids: 56 cores, 350W and 64GB of HBM2!

Shared by the site videocardz, an old slide (when the Xeon Ice Lake were planned for the year 2020) comes to confirm us the specifications of the next generation of Intel server processors, namely Sapphire Rapids.

Intel Xeon Sapphire Rapids

First of all, Sapphire Rapids will be based on the new 10nm Enhanced Superfin etch and will use Golden Cove cores expected to offer +20% IPC.

As for Alder Lake on the consumer market, SPR on the professional market will replace two generations, namely Cooper Lake and Ice Lake SP, offering up to 56 cores. They will be distributed on 1/2/4 or 8 sockets, with a power consumption up to 350W, against 270W currently for Ice Lake SP.

The DDR5 and PCIE 5.0 will also be part of the game with 8 memory channels and a frequency up to 4800 Mhz. We will also have 80 PCIE 5.0 lines in x16, x8, x4 and 2 PCIE 4.0 lines. Let’s stay on the memory side, with the introduction of the HBM2 on-package, allowing to integrate up to 64 GB, offering a bandwidth of 1 TB/s per processor.

A small amount of 56 cores available?

In addition, another leaker momomo_us, had shared information on several versions and their “availability”.

We discover 3 different versions: 24 cores at 225W which would have a low volume of production, 44 cores at 270W which could represent the version with a large volume and the 56 cores 350W which would have a low binary (and thus a low volume?).
