Intel Says Meteor Lake & Raptor Lake CPUs Have Very Similar P-Core & E-Core Architectures, Intel 4 Brings Efficiency Improvements

wccftech.com:

Intel has revealed that Meteor Lake P-Cores & E-Cores are architecturally very much alike to Raptor Lake but there are some improvements with the Intel 4 process node bringing in higher efficiency.

The Intel Meteor Lake, 1st Gen Core Ultra, CPUs are scheduled for launch on the 14th of December & the company recently unveiled a whole lot of details regarding the latest chips at Innovation 2023 which we covered here. The CPUs will be making use of advanced packaging technologies, a brand new process node, and new cores but will also be very architecturally similar to Intel's Raptor Lake CPUs.

In an interview with ITHome, Intel's Timothy Wilson, who acts as the VP of Design Engineering Group and General Manager of the SOC Design division, revealed that Meteor Lake CPUs are architecturally similar when it comes to the types of cores they both feature. We know that Intel is equipping Meteor Lake chips with new P-Cores codenamed Redwood Cove & E-Cores codenamed Crestmont.

Intel Meteor Lake & Raptor Lake E-Core Architecture:

Initially, it was thought that these cores would bring a bigger upgrade over Raptor Lake's P-Core codenamed Raptor Cove and E-Core codenamed Gracemont but it looks like the design will be very similar. In fact, even Raptor Cove's architecture is essentially an enhancement of the Alder Lake P-Core codenamed Golden Cove while the E-Cores are the same. Following is the statement:

Compared to the previous generation of Raptor Lake, the microarchitecture of both the P and E cores in Meteor Lake has some improvements. However, we introduced Meteor Lake with the new Intel 4 process. In general, when we introduce new processes, we tend to reduce the risk in terms
