intel-meteor-lake-cpu’s-redwood-cove-p-cores-use-similar-architecture-as-golden-cove,-new-architecture-for-e-cores

New info concerning Intel’s 14th Gen Meteor Lake CPUs has been revealed within the firm’s Open Source database by Coelacanth-Dream. As per the small print, it appears like Meteor Lake CPUs can be a refinement of the prevailing Golden Cove cores whereas that includes a model new structure for the E-Cores.

Intel 14th Gen Meteor Lake CPUs: Redwood Cove P-Cores With Same Architecture & Tweaks, Crestmont E-Cores With New Architecture

The particulars reveal that Intel’s 14th Gen Meteor Lake CPUs will as soon as once more make the most of a hybrid method which should not be a shock by now. The Native Model ID for every hybrid CPU household has been listed, beginning with the Lakefield which has 0x0 “Core” and “0x0” Atom household. Lakefield SOC was Intel’s first design primarily based on a hybrid structure method. Since then, Intel has launched its twelfth Gen Alder Lake and can quickly be launching the upcoming thirteenth Gen Raptor Lake CPUs.

As I discuss it in May, RWC like SNC, is not going to widen the microarchitecture loopy like Alder lake.

RPC is completely different, it focuses on the core stage enchancment as an alternative of uarch.https://t.co/tloWXyqQL2

Native ID is uArch’s ID.

Crestmont has completely different ID from Gracemont. So It is completely different uArch.

Redwood Cove has similar ID with Golden Cove. So it’s essentially similar uArch.

The Intel twelfth Gen Alder Lake CPUs function the 0x0 “Core” also called the Golden Cove P-Core and 0x1 “Atom” also called the Gracemont E-Core. Intel’s thirteenth Gen Raptor Lake CPUs will retain this design, nevertheless, resulting from numerous adjustments made on a core stage (to not be mistaken with Uarch), the corporate has determined to rename its P-Cores to Raptor Cove. We have seen some adjustments similar to cache bump, and clock bump however these are hardly any architectural uplifts.

Native Model ID


(Coelacanth-Dream)
Type: Core Type: Atom
Lakefield 0x0 0x0
Alder Lake 0x1 0x1
Raptor Lake 0x1 0x1
Meteor Lake 0x1? 0x2

Now coming to 14th Gen Meteor Lake CPUs, the Redwood Cove P-Cores are as soon as once more anticipated to be primarily based on the 0x1 “Core” design which implies that whereas there can be Core-level upgrades, the structure will kind of stay the identical. On the opposite hand, the “Atom” E-Cores referred to as Crestmont, can be upgraded to 0x2 Native Model.

OneRaichu explains that Redwood Cove is not going to widen the structure as a lot as Sunny Cove cores and can primarily deal with instruction execution effectivity. It will be considered 0x1.5 since there are talks of enhancements to department prediction, micro-operation fusion, instruction dispatch, register remake, and EU execution effectivity. While Intel Meteor Lake CPUs make the most of the model new “Intel 4” course of node, the node will not be as mature as 10ESF and we will see a clock regression that can be unable to match the excessive frequencies that Raptor Lake has to supply.

Meanwhile, the IPC can be higher than Raptor Lake however single-threaded efficiency will not see an enormous acquire. Previous rumors had already hinted that Meteor Lake will provide single-digit IPC good points vs Raptor Lake however these can be sufficient to hold AMD CPUs at bay for some time till Arrow Lake comes out in 2024.
