AMD has hit Intel hard in all CPU segments but its the server segment where the blue team has seen the full might of Zen-based EPYC processors. Intel's iconic Xeon lineup has been disrupted since the arrival of the first generation EPYC CPUs codenamed Naples and the lead was extended with the second generation EPYC lineup, codenamed Rome. However, Intel's first 10nm family is shipping out later this year and as per the latest rumors, it's next-generation 10nm family will be making its way to the server segment by 2021.

Intel 10nm Sapphire Rapids Xeon Scalable Family To Go Against AMD's 4th Gen EPYC Genoa Server CPUs By Late 2021

Intel has so far confirmed that it's Ice Lake family hits the streets around Q4 2020 which would be around the same time AMD introduces its 3rd Generation EPYC Milan CPUs based on the new Zen 3 core architecture. The Ice Lake CPUs, in general, will be Intel's first 10nm server processor lineup, featuring the Sunny Cove core architecture, PCIe Gen 4 support, and a range of new features. But AMD, on the other hand, would make use of a refined 7nm process node along with an upgraded CPU architecture 'Zen 3', which is expected to deliver some big IPC gains.

But its neither Intel's 10nm Ice Lake or AMD's 7nm EPYC Milan that is the topic of today's discussion but its rather the parts succeeding them in 2021. In a leaked roadmap from Intel Russia which was spotted by Momomo_US a few days ago, we get to see some more information on where the Intel Xeon Scalable Family is headed with its next-generation Eagle Stream Platform which will support 2 major Xeon families, Sapphire Rapids & Granite Rapids.

In a previous article, we reported that Sapphire Rapids will utilize an enhanced 10nm process node whereas Granite Rapids will be Intel's first 7nm process-based server lineup. The Intel Eagle Stream platform is suggested to continue till 2023 with Sapphire Rapids coming in late 2021 while Granite Rapids could deploy around late 2022 or early 2023. In its roadmap, Intel also shows that Sapphire Rapids will bring a new architecture which is hinted by the dark blue color that refers to a Tock while Granite Rapids would bring forth a smaller process node, also referred to as a Tick and hinted by light blue color.
