Meteor Lake = Redwood Cove + Crestmont

A confirmation on the microarchitecture used by Meteor Lake CPU series.

The rumors about Redwood Cove architecture are dated as far back as November 2020, when it was first mentioned by Moore’s Law is Dead . This rumor is finally finding its confirmation though leaked Microsoft Perfmon logs.

According to the data shared by @InstLatX64 , upcoming 14th Gen Core “Meteor Lake” will feature two architectures: the big core known as Core/Performance will be based on Redwood Cove microarchitecture, while the small/Efficient core is supposedly based on Crestmont.

Meteor Lake is a successor to Raptor Lake, a new hybrid architecture designed for desktops and mobile devices. It should not be expected sooner than next year though. This architecture will be the first consumer product series to feature Intel 4 process technology.

Furthermore, Meteor Lake is to feature an entirely new Intel Xe-LPG graphics architecture with increased core count. Intel teased up to 192 Execution Units, while recent leaks suggest it’s actually 128EU for the laptop series.

The 14th Gen Core series may also ship with a third type of core implemented into the SoC die (not Compute). Only two such low-power cores are to be used by Meteor Lake CPUs.
