Hot Chips 2023: Intel Details More on Granite Rapids and Sierra Forest Xeons

With the annual Hot Chips conference taking place this week, many of the industry’s biggest chip design firms are at the show, talking about their latest and/or upcoming wares. For Intel, it’s a case of the latter, as the company is at Hot Chips to talk about its next generation of Xeon processors, Granite Rapids and Sierra Forest, which are set to launch in 2024. Intel has previously revealed this processors on its data center roadmap – most recently updating it in March of this year – and for Hot Chips the company is offering a bit more in the way of technical details for the chips and their shared platform.

While there’s no such thing as an “unimportant” generation for Intel’s Xeon processors, Granite Rapids and Sierra Forest promise to be one of Intel’s most important updated to the Xeon Scalable hardware ecosystem yet, thanks to the introduction of area-efficient E-cores. Already a mainstay on Intel’s consumer processors since 12^th generation Core (Alder Lake), with the upcoming next generation Xeon Scalable platform will finally bring E-cores over to Intel’s server platform. Though unlike consumer parts where both core types are mixed in a single chip, Intel is going for a purely homogenous strategy, giving us the all P-core Granite Rapids, and the all E-core Sierra Forest.

As Intel’s first E-core Xeon Scalable chip for data center use, Sierra Forest is arguably the most important of the two chips. Fittingly, it’s Intel’s lead vehicle for their EUV-based Intel 3 process node, and it’s the first Xeon to come out. According to the company, it remains on track for a H1’2024 release. Meanwhile Granite Rapids will be “shortly” behind that, on the same Intel 3 process node.
