Intel Launches Meteor Lake Architecture, Delivering Artificial Intelligence, Efficiency, and Enhanced Graphics Performance

Recently, Intel finally unveiled the mystery of its Meteor Lake architecture. The company stated that this is the most significant change it has made to CPU architecture in the past 40 years, and this design will serve as the foundation for its CPUs for at least the next decade.

Intel adopts a tile-based design

Meteor Lake uses four tile blocks to compose the CPU, instead of a monolithic design, which is a first for Intel. These four tiles are CPU, GPU, SoC, and I/O, and they are manufactured using three different processes from two different foundries. Intel manufactures the CPU module using its own Intel 4 process (previously known as 7nm), while TSMC manufactures the other modules. The SoC and I/O modules are built on the N6 process, while the Arc GPU module is manufactured using TSMC's 5nm node.

The CPU block features new performance and efficiency cores. A chart shared by Intel shows 6 P cores and 8 E cores, confirming previous rumors that Meteor Lake will have fewer cores than Raptor Lake due to its focus on efficiency.

Powerful SoC Tile

The most interesting tile, in our opinion, is the SoC tile, as it integrates many new technologies and appears to be larger than the other tiles. The most significant change here is that Intel has added two low-power cores to this tile, called "low-power island" cores. They are designed to handle very lightweight tasks without waking up other cores, which should greatly improve efficiency. These cores use the same architecture as the regular E cores but are designed for low-power operation, while the other E cores are optimized for multi-core loads. All three types of cores will be visible in the task manager, so they are not hidden from the system.

In addition to the new cores, a Neural Processing Unit (NPU) or AI accelerator is also located on this tile. We are not sure what functionality it will provide, but Intel believes its presence will popularize AI and allow more people to experience AI. According to Intel, this NPU on Meteor Lake will enable millions of people to experience AI firsthand.

As if one tile is not enough, Intel has also added support for Wi-Fi 6e and Wi-Fi 7, as well as HDMI 2.1 and DisplayPort 2.1 connections. This tile also has built-in media and display hardware, including support for AV1 encoding and 8K HDR output. This theoretically allows this tile to handle some graphics work without the need for the GPU tile.

GPU Tile

Intel refers to the iGPU on Meteor Lake as Xe LPG, which includes all the advancements it has made on its discrete Arc GPU. It claims that this tile offers twice the performance per watt compared to the UHD 770 iGPU embedded in its Alder Lake CPUs. In some marketing materials, Intel claims that it will provide performance similar to dedicated desktop GPUs, which is a high demand. However, Intel states that it will be powerful enough to handle ray tracing, which will be a first for integrated graphics. Intel has also added its upsampling technology, called XeSS, to this iGPU, competing with DLSS and FSR.

EUV, Foveros, and Intel 4

With the release of Meteor Lake, Intel will complete the transition from 10nm to 7nm, which is a significant milestone for anyone who remembers the company's struggles from 14nm to 10nm. It is also its first implementation of Extreme Ultraviolet Lithography (EUV), making Intel the last major foundry to join this technology. The company claims that it provides more precise lithography with a 2x improvement in area compared to Intel 7. Intel also estimates that Intel 4 offers 20% higher efficiency than Intel 7.

It is also the first consumer CPU to use Foveros chip stacking technology, which will be used in all future Intel CPUs. It consists of four blocks installed on top of a base/interposer layer, with exposed through-silicon vias (TSV) to allow communication between the blocks. Intel manufactures the Foveros Tile and states that despite the tile-based design, its performance is comparable to monolithic structures.

New P and E cores and updated Thread Director

Meteor Lake increases the instructions per clock (IPC) for the Redwood Cove P cores and Crestmont E cores, and also mentions that both types of cores have improved Thread Director "feedback." This includes providing smarter "hints" to the Windows scheduler, indicating which cores should handle specific tasks. Intel states that it has collaborated with Windows to design Meteor Lake for better power management among all three types of cores.

All for AI

Despite these advancements in power management and efficiency, Intel may focus on the AI applications of Meteor Lake CPUs, as it believes this will be a key selling point. AMD recently introduced the Ryzen AI Engine in its 7040 series APUs, so Intel seems to be aiming to surpass its competitors in this field.

It is referred to as "massive AI" and its marketing slogan is that it will bring device-side AI to millions of users, rather than relying on cloud-based AI as it is currently done. We will have to wait for more specific details later this week, but Intel is clearly catching up with this trend. However, to be fair, these projects have been in the works for many years, so it appears that Intel had this strategy in place before ChatGPT became a thing.

Intel is not yet ready to discuss specific CPUs, specifications, and pricing, but we expect them to be announced later this week. The Core Ultra CPUs of Meteor Lake will be available on December 14th.
