Intel officially confirms that Alder Lake will be a Hybrid CPU architecture with two new core designs

Alder Lake will be a client product which combined Golden Cove and Gracemont CPU cores to deliver a bland to ultra-high performance levels and great performance/watt. 

Golden Cove will succeed Tiger Lake’s Willow Cove core design, promising stronger single-threaded performance, enhanced AI performance, new security features and new networking capabilities. Gracemont will replace the Tremont cores that are found within today’s Lakefield processors, promising users higher frequencies, stronger single-threaded performance and enhanced vector performance. 

In conjunction with Intel’s new 10nm SuperFin transistors and improved manufacturing/packaging technologies, Alder Lake should deliver consumers a significant performance and efficiency uplift over today’s product offerings. That said, Intel has committed to “shipping” Alder Lake in the second half of 2021, which means that it will be competing with next-generation offerings from AMD. 

With Tiger Lake having confirmed PCIe 4.0 support, it is probable that Alder Lake will also support PCIe 4.0, and benefit from the same performance enhancements as Tiger Lake as well as additional enhancements through additional architectural shifts.
