4th Gen Xeon Scalable series to launch January 10th

Intel confirmed the release date of its new data-center products. 

After countless delays, Intel Sapphire Rapids series finally have a release date. The new data-center CPU series based on Intel 7 process technology is set to arrive on January 10th, the company confirmed yesterday.

Intel is ready to introduce products that have ‘met product release qualifications’, according to the official information. This likely means that not all known Sapphire Rapids SKUs will be introduced at the same time, but this is still better than not launching any product at all. Sapphire Rapids has seen as many as 12 different steppings through its development, and the release date has been pushed back many times.

According to TrendForce reasearch, Intel faces Sapphire Rapids production delays due to poor yields of the Intel 7 process. This is the same 10nm node that is used by Alder Lake and Raptor Lake. Such a report is contrary to Intel calling this node ‘healthy’ a few months ago, hence this quote should be taken with a grain of salt.

According to the latest TrendForce research, the mass production schedule of new Sapphire Rapids products has been delayed due to the poor yield rate of the Intel 7 process. At present, the production yield rate of Sapphire Rapids is estimated at only 50~60%, which affects mainstream Sapphire Rapids MCC products.

Intel Sapphire Rapids is designed for “Eagle Stream” platform that will support PCIe Gen5 and DDR5 technologies. It will also be compatible with the successor called “Emerald Rapids”, which is set to launch in the same year. The new data-center CPU series will offer up to 56 cores based on “Golden Cove” architecture, which are all big aka ‘Performance’ cores.
