Intel Says Meteor Lake & Raptor Lake CPUs Have Very Related P-Core & E-Core Architectures, Intel 4 Brings Effectivity Enhancements

Intel has revealed that Meteor Lake P-Cores & E-Cores are architecturally very a lot alike to Raptor Lake however there are some enhancements with the Intel 4 course of node bringing in greater effectivity.

Intel Meteor Lake Redwood Cove P-Cores & Crestmont E-Cores Are Very Related To Raptor Lake’s Raptor Cove P-Cores & Gracemont E-Cores

The Intel Meteor Lake, 1st Gen Core Extremely, CPUs are scheduled for launch on the 14th of December & the corporate just lately unveiled an entire lot of particulars relating to the most recent chips at Innovation 2023 which we lined right here. The CPUs will likely be making use of superior packaging applied sciences, a model new course of node, and new cores however can even be very architecturally much like Intel’s Raptor Lake CPUs.

In an interview with ITHome, Intel’s Timothy Wilson, who acts because the VP of Design Engineering Group and Normal Supervisor of the SOC Design division, revealed that Meteor Lake CPUs are architecturally related relating to the sorts of cores they each characteristic. We all know that Intel is equipping Meteor Lake chips with new P-Cores codenamed Redwood Cove & E-Cores codenamed Crestmont.

Intel Meteor Lake & Raptor Lake P-Core Structure:

Intel Meteor Lake & Raptor Lake E-Core Structure:

Initially, it was thought that these cores would deliver a much bigger improve over Raptor Lake’s P-Core codenamed Raptor Cove and E-Core codenamed Gracemont but it surely seems just like the design will likely be very related. Actually, even Raptor Cove’s structure is actually an enhancement of the Alder Lake P-Core codenamed Golden Cove whereas the E-Cores are the identical. Following is the assertion:

In comparison with the earlier era of Raptor Lake, the microarchitecture of each the P and E cores in Meteor Lake has some enhancements. Nevertheless, we launched Meteor Lake with the brand new Intel 4 course of. Basically, once we introduce new processes, we have a tendency to cut back the chance when it comes to structure. As soon as we obtain a steady course of stream, we are likely to make a much bigger leap by enhancing the structure. So, since it is a new large node replace for us, and we will additionally get the power effectivity advantages of Intel 4, we have made only a few adjustments to the core structure, so that they’re architecturally similar to Raptor Lake’s E-cores and P-cores.

Timothy Wilson (Vice President of Design Engineering Group & Normal Supervisor of SOC Design at Intel) by way of ITHome

Timothy states that whereas there will likely be some architectural enhancements, they are not as vital since Meteor Lake CPUs are constructed on a model new node and people larger upgrades will come as soon as the method turns into extra steady and higher when it comes to total yields. So it seems like Intel went with a much less dangerous route with its first EUV and chiplet design. The larger improve is more likely to come within the following 12 months within the type of Arrow Lake which additionally provides new P-Cores and E-Cores and makes use of the Intel 20A course of node.

So speaking concerning the cores themselves, the Intel P-Core, codenamed Redwood Cove, is focused for environment friendly efficiency by enhancing the general chip effectivity, elevated bandwidth (per core), an improved efficiency monitoring unit, and improved suggestions by means of Intel’s Thread Director. Every P-Core contains a 2 MB ML Cache, 64 KB I-Cache, and 48 KB Knowledge Cache.

For the E-Core which is codenamed Crestmont, Intel is claiming vital features over the earlier E-Core (Gracemont) with will increase in IPC, AI Acceleration, a brand new and enhanced model prediction & improved suggestions with the most recent iteration of Intel’s Thread Director. The E-Core options as much as 4 MB of L2 cache, 32 KB Knowledge Cache (w/ECC), and 64 KB I-Cache.

There’s additionally a low-power model of the identical Crestmont E-Core packed throughout the SoC Tile which is used for max effectivity whereas the non-LP E-Cores provide environment friendly multi-threaded efficiency. It’s also talked about that whereas the architectural adjustments are usually not that large, the Intel 4 course of node itself results in some good features when it comes to total energy effectivity. In accordance with ZDNet, the Meteor Lake CPUs will likely be heading out later this 12 months in numerous laptops and mobility kind elements together with AIOs & pre-built desktop PC designs by the tip of this 12 months.
