Intel Meteor Lake CPU P-Core Redwood Cove uses a similar architecture to Golden Cove, a new architecture for electronic cores

New information on Intel’s 14th generation Meteor Lake processors has been revealed in the Coelacanth-Dream Open Source database. In terms of detail, it looks like the Meteor Lake processors will be an improvement over the existing Golden Cove cores, while also featuring a completely new architecture for the E-Core.

The details show that Intel’s 14th-generation Meteor Lake processors will once again use a hybrid approach, which shouldn’t come as a surprise now. The Native Model ID for each Hybrid CPU family is listed, starting with Lakefield which has the Atom 0x0 “Core” and “0x0” families. Lakefield SOC was Intel’s first project based on a hybrid architecture approach. Intel has since launched the 12th Gen Alder Lake and will soon be launching the upcoming 13th Gen Raptor Lake processors.

The 12th generation Alder Lake Intel processors have 0x0 core, also known as Golden Cove P-Core and 0x1 atom, also known as Gracemont E-Core. Intel’s 13th-generation 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 rename its P-Cores to Raptor Cove. We’ve seen some changes like a cache boost and a clock boost, but these aren’t any architectural improvements.

Type: core Type: Atom
Lakefield 0x0 0x0
Olchowe Lake 0x1 0x1
Raptor Lake 0x1 0x1
Meteora lake 0x1? 0x2

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

One Raichu explains that Redwood Cove will not extend the architecture as much as the Sunny Cove cores and will mainly focus on instruction execution performance. It can be considered 0x1.5 as it talks about improvements to branch prediction, micro-op fusion, instruction dispatch, registry rework, and UE execution performance. While the Intel Meteor Lake processors use the brand new “Intel 4” process node, this node may not be as mature as the 10ESF, and we can see clock regression that will not be able to match the high frequencies offered by Raptor Lake.

Meanwhile, IPC will be better than Raptor Lake, but single-threaded performance won’t bring a huge boost. Previous rumors have already suggested that Meteor Lake will offer single-digit IPC gains over Raptor Lake, but that will be enough to keep AMD processors at bay until Arrow Lake arrives in 2024.
