Intel "Willow Cove" Backported to 14nm is "Cypress Cove"?

Intel's 11th generation Core "Rocket Lake-S" desktop processor is fascinating as it introduces Intel's first CPU core IPC uptick in about half a decade. Until now, it was rumored that "Rocket Lake-S" features a back-port of Intel's "Willow Cove" CPU cores to the 14 nm silicon fabrication process. It turns out that Intel doesn't want to call these cores "Willow Cove," which make their debut with the 10 nm+ "Tiger Lake" mobile processors later this Summer. Enter "Cypress Cove." A Moore's Law is Dead video presentation sheds light on this mysterious new codename.

Apparently, "Cypress Cove" is the codename Intel is using to refer to the CPU cores Intel is building with its latest CPU core IP on older 14 nm process. Owing to the process, the IPC of these cores may be different from the "Willow Cove" cores on "Tiger Lake," and to avoid confusion, Intel possibly choosing to give it a different internal codename. In other words, Moore's Law is Dead believes that "Cypress Cove" may not offer the alleged 25% IPC gains over "Skylake" that you could expect instead from "Willow Cove" cores in "Tiger Lake."
