At this 12 months’s Intel Innovation developer convention, CEO Pat Gelsinger proclaimed “We’re ushering in a brand new age of AI PC.” He was speaking concerning the subsequent era of Intel pocket book PC processors, code named Meteor Lake. Meteor Lake incorporates a brand new Neural Processing Unit (NPU) to service AI workloads on edge units and as Gelsinger says, “unleashing private productiveness and creativity.”
To show the purpose, Gelsinger introduced Jerry Kao, COO of Acer on stage at Innovation to demo the suite of Acer AI purposes constructed with Intel’s help and the OpenVINO toolkit. It included a built-in AI picture era and a parallax responsive display screen wallpaper impact primarily based on eye monitoring.
You get an NPU, and also you get an NPU, and…
Whereas Meteor Lake’s new NPU is a ground-breaking change to Intel PC processors, it’s not the primary NPU in a PC processor. It comes on the heels of AMD’s Ryzen 7040 sequence of pocket book processors with Ryzen AI NPUs. And neither AMD nor Intel are the primary to convey an NPU to Home windows PCs – Qualcomm’s Snapdragon processors for Home windows-on-Arm PCs have all had Hexagon NPUs, which is a part of the Qualcomm Synthetic Intelligence (AI) Engine. Maybe Microsoft noticed the advantages of NPUs in Home windows primarily based on its Snapdragon expertise, and it inspired AMD and Intel so as to add NPUs as effectively. Why else would each AMD and Intel be including NPUs on the similar time? Or, it could possibly be that Apple having a Neural Engine in its M1 processor for its Arm-based Mac and MacBook merchandise signaled that NPUs at the moment are going to be a big processing component in all PCs going ahead. In any case, Home windows PCs will quickly have vital AI functionality, one thing smartphones have had for a while.
Intel Innovation 2023 Meteor Lake Options
Intel
Constructed with Intel Foveros
Intel has additionally stepped up its sport on chiplets (which Intel likes to name “tiles”). Chiplets are smaller useful models on separate silicon die that may be mixed in a package deal to kind the system-on-chip (SoC). Prior to now, SoCs tended to have all of the parts on one bigger silicon die, known as a monolithic die. AMD pioneered the chiplet method with its Ryzen and Epyc processors and nonetheless makes use of it as we speak. Intel has used chiplets and superior packaging for server and FPGA processors with both its EMIB or Foveros applied sciences.
Intel’s method for Meteor Lake makes use of its Foveros expertise, which stacks the chiplet die on a service or base die. The bottom die has interconnects routing to attach the 4 chiplets that kind a Meteor Lake processor. Every chiplet has a definite perform and a definite semiconductor course of.
The 4 chiplets are: the Compute Tile, the SoC Tile, the Graphics Tile and the IO Tile.
The Compute Tile combines the efficiency “P” x86 cores and the environment friendly “E” CPU cores with the CPU reminiscence caches. This chiplet is constructed on the Intel 4 course of that makes use of EUV processing. A lot of the heavy CPU processing takes place within the Compute Tile. Intel’s Thread Director manages how every kind of core is used for a selected workload. A online game will possible be allotted to the P cores, whereas a community stack can run superb on E cores.
In a bid to additional enhance battery life, Intel positioned further E cores on the SoC Tile. This second set of E cores are optimized for even decrease energy. The SoC Tile additionally consists of the media and show processors, reminiscence controllers and the NPU. This power-optimized chiplet can play video with out powering up the Compute Tile or the Graphics Tile, making it a power-efficient media processor.
The SOC Tile is produced utilizing the TSMC 6nm course of, which implies Intel needed to switch its E cores to the TSMC course of.
The Graphics Tile makes use of the TSMC N5 course of. It’s primarily based on Intel’s newest Arc GPU era and affords twice the graphics efficiency of its predecessor. The IO Tile has PCIe Gen 5 and Thunderbolt 4.
Intel will be capable of combine and match its chiplets utilizing totally different course of nodes and totally different fabs to supply optimized SKUs for various segments. It might additionally reuse tiles in future merchandise. Chiplets mixed with Intel’s EMIB and Foveros packaging applied sciences supplies Intel further product flexibility and price optimizations. The corporate has utilized its modern Intel 4 processor the place it’s wanted – within the CPU advanced.
Intel additionally laid out its roadmap for notebooks: “Contemporary out of the fab with our Arrow Lake processor,” Pat says, constructed on the Intel 20A course of. “It’s working as anticipated.” It is going to be adopted by Lunar Lake in 2024 and Panther Lake in 2025. Panther Lake is scheduled for a Q1/2024 tape out and can use the Intel 18A course of. These course of name outs are most likely just for the Compute Tiles.
Intel Pocket book Processor Roadmap

Abstract
Intel has pushed its benefit in packaging to a brand new stage and this disaggregated processor alerts a brand new future for its PC processors. With the addition of an NPU, you may anticipate new native AI capabilities on PCs operating on Intel and a extra private PC.
Intel’s new Meteor Lake pocket book processor might be bought beneath the Intel Core Extremely model and can launch on December 14th. We anticipate to listen to about new desktop processors from Intel later within the 12 months. And whereas Meteor Lake is designed for notebooks, we wouldn’t be shocked to see it in some modern desktop merchandise in 2024.
