A Linux kernel patch contributed and signed off by Intel confirms that its upcoming Core "Alder Lake" processor will feature a hybrid core topology, much like Core Hybrid "Lakefield." The patch references "Lakefield" and "Alder Lake" under "Hybrid Core/Atom Processors." The patch possibly gives the Linux kernel awareness of the hybrid core topology, so it can schedule its work between the two types of cores on the silicon accordingly, and avoid rotating between the two core groups. Under the Android project, Linux has been aware of a similar tech from Arm since 2013.

Analogous with Arm big.LITTLE, the Intel Hybrid Core technology involves two kinds of CPU cores on a processor die, the first kind being "high performance," and the second being "low power." On "Lakefield," Intel deployed one "Sunny Cove" high performance core, and four "Tremont" low power cores. The low power cores keep the machine ticking through the vast majority of time when processing workloads requiring the high performance cores aren't present. With "Alder Lake," Intel is expected to scale up this concept, with the silicon rumored to feature eight "Golden Cove" high performance cores, and eight "Gracemont" low power ones. The chip is also expected to feature a Gen12 Xe iGPU.

Sapphire Rapids X is in there as well. That's 10nm Willow Cove, planned for 2021.

Certainly.
But regarding Sapphire Rapids, there are a lot of conflicting information floating around. I suspect it might be Golden Cove. Sapphire Rapids has been known as a major new architecture for ~5 years. Willow Cove (used in Tiger Lake) is a refined Sunny Cove.

But it's just more bullshit. They can't even make icelake Xeon, but they're gonna hype (aka intentionally leak) the successor with tons of cores...bwhahahaha.

They might as well pack it up like Glofo.
