Intel confirms Alder Lake is using Hybrid Core/Atom architecture

Intel has issued a Linux patch adding Alder Lake Intel processor family support.

Intel confirms Alder Lake is a Hybrid Atom/Core architecture

This is a confirmation that Intel Alder Lake series will feature Big and Small core architecture, where the latter is derivative of Atom, a comment from Intel employee seems to suggest.

+#define INTEL_FAM6_LAKEFIELD 0x8A
+#define INTEL_FAM6_ALDERLAKE 0x97

As the code reveals, Alder Lake will be Intel’s second hybrid architecture, following just released Lakefield series for ultra-low power devices. The Lakefield is using Foveros die stacking technology, but so far no rumors have suggested that Alder Lake could also use such technology.

Intel Alder Lake is now rumored to be the first 10nm mainstream desktop series. It would also use a newer core design (Golden Cove) paired with Gracemont’s small cores. Additionally, the CPU would be equipped with integrated Xe Graphics.

The series will introduce a new socket for Intel desktop processors, LGA1700. The new platform is expected to support both PCIe 4.0 and DDR5 technology.

While the upcoming 11th Gen Core series (Rocket Lake) will bring new core architecture (Willow Cove), it would still rely on the 14nm fabrication process. That said, Alder Lake is expected to be the biggest architectural improvement for Intel in years.
