The Intel Meteor Lake Processor’s Redwood Cove P Cores use an architecture similar to Golden Cove, a new architecture for electronic cores

New information regarding Intel’s 14th Gen Meteor Lake processors has been revealed in the company’s open source database by Coelacanth-Dream. Going by the details, it looks like the Meteor Lake CPUs will be a refinement of the existing Golden Cove Cores while featuring an all-new architecture for the E-Cores.

The details reveal that Intel’s 14th Gen Meteor Lake processors will once again use a hybrid approach, which shouldn’t come as a surprise anymore for now. The native model ID for each hybrid processor family has been listed, starting with the Lakefield which has family 0x0 “Core” and “0x0” Atom. Lakefield SOC was Intel’s first design based on a hybrid architecture approach. Since then, Intel has launched its 12th Gen Alder Lake and will soon launch the upcoming 13th Gen Raptor Lake processors.

12th Gen Intel Alder Lake processors feature 0x0 “Core” also known as Golden Cove P-Core and 0x1 “Atom” also known as Gracemont E-Core. Intel’s 13th Gen Raptor Lake processors will retain this design, however, due to various core-level changes (not to be confused with Uarch), the company has decided to rebrand its P-Cores to Raptor Cove. We saw a few changes such as the cache bump and the clock bump, but these are hardly architectural improvements.

Type: Core Type: Atom
Lakefield 0x0 0x0
Alder Lake 0x1 0x1
raptor lake 0x1 0x1
meteor lake 0x1? 0x2

Now coming to the 14th Gen Meteor Lake processors, the Redwood Cove P-Cores are again expected to be based on the 0x1 “Core” design, which means that while there will be upgrades at the core level, the architecture will remain more or less the same. On the other hand, “Atom” E-Cores known as Crestmont, will be upgraded to the native 0x2 model.

A Raichu explains that Redwood Cove will not expand the architecture as much as the Sunny Cove cores and will focus primarily on instruction execution efficiency. It can be considered 0x1.5 because it talks about improvements in branch prediction, micro-op merging, instruction dispatch, register remake, and execution efficiency of the EU. While the Intel Meteor Lake processors use the brand new “Intel 4” process node, the node may not be as mature as 10ESF and we may see clock regression that won’t be able to match the high frequencies that Raptor Lake has to offer.

Meanwhile, IPC will be better than Raptor Lake, but single-threaded performance won’t see a huge gain. Previous rumors had already hinted that Meteor Lake would offer single-digit IPC gains over Raptor Lake, but those would be enough to keep AMD CPUs at bay for quite some time until Arrow Lake is released in 2024. .
