Intel Panther-Lake CPUs to debut new ‘Cougar Cove’ P-cores

Intel might have made some changes to their client CPU roadmap. Besides the alleged cancellation of Meteor Lake for desktop platforms, a new report has shed some light on Intel's plans beyond Arrow Lake. For the 15th Gen Core series, we'll reportedly have Panther-Lake featuring Cougar Cove P-cores.

Moore's Law Is Dead claims Meteor Lake won't be coming to desktops. As such, the debut of the LGA-1851 socket was delayed to Q4 2024, coinciding with the launch of the Arrow Lake desktop platform. The Arrow Lake (ARL) series is expected to bring significant performance improvements. The series will feature up to 40 cores, with up to 8 performance cores and up to 32 efficient cores. This increase in core count alone will result in higher multi-threaded performance, with the report pointing to a 40% improvement over Meteor Lake.

Arrow Lake will predominantly be manufactured using TSMC nodes, particularly for the high-end compute dies such as 8P+32E, 8P+16E, and 6P+8E. Intel plans to release at least five different dies for Arrow Lake, including the three dies previously mentioned, as well as the Intel 20A-based 6P+8E and 2P+8E dies. Additionally, there is speculation about a potential downgrade of the integrated GPU, with the highest core count possibly reduced to 192 Execution Units (EU) instead of the originally planned 320 units. Arrow Lake is expected to debut in Q4 2024.

The report also suggests that the next generation of mainstream CPUs following Arrow Lake will be Panther-Lake, which will introduce a new core architecture called Cougar Cove. This architecture is expected to target the 8P+32E configuration and is projected to deliver a significant leap in single (30-40%) and multi-threaded performance (15-20%) over Arrow Lake. Notably, the Panther Lake architecture will be socket compatible with Arrow Lake.

Furthermore, a new codename, “Beast Lake,” is mentioned, which aims to achieve single-core performance leadership. Moreover, it could potentially feature more than 8 Performance cores. Intel documents reference at least 14 SKUs, but specific details regarding these SKUs have not been disclosed at this time.

KitGuru says: Intel has an interesting roadmap ahead but plans can change when talking about products still a year or more away from release.
