For a lot of months, Intel has spared no alternative to remind us that its Meteor Lake chips could be those to observe — its first CPU with completely different chiplets for every element; its first on its Intel 4 course of node; its first with a devoted AI coprocessor inside. At this time, Intel is revealing a complete lot extra.

Meteor Lake will “launch” on December 14th, the corporate now says, as probably the most power-efficient shopper processor the corporate’s ever made — and with as much as twice the graphics efficiency, a “low energy island” that may run duties independently, and hooks into Microsoft Home windows to intelligently management the brand new chips.

In no specific order, listed below are the highlights of Intel’s Core Extremely — as a result of yeah, this one’s not referred to as a Core i7.

It’s product of tiles

With Meteor Lake, Intel will be a part of its friends in crafting laptop chips out of Lego-like constructing blocks — the place the “CPU” and “GPU” aren’t simply separate elements on the identical chip, for instance, however really separate items of silicon printed at completely different sizes and grafted collectively. The likes of AMD and Qualcomm have been doing this for some time, however heterogeneous computing is comparatively new to Intel.

The draw back for you is that solely a part of Intel’s chip is definitely on the corporate’s bleeding-edge Intel 4 course of. The graphics are on TSMC’s 5nm course of, and the I/O and new “SoC Tile” are on TSMC N6. However the upside is that corporations can select one of the best constructing blocks — and selectively minimize off energy to the remainder.

Proper out of the gate, no pun supposed, Intel is trying to make use of chiplets to radically scale back how a lot energy its processors draw. And it’s doing so by taking a number of the “Central” out of CPU.

As a substitute of a single CPU or show area of the chip, every Meteor Lake has two — one on a “low energy island” that may theoretically run all by itself, with its personal effectivity CPU core, NPU AI coprocessor, media engine, and reminiscence.

The low energy island is “preferrred for a complete class of workloads that care concerning the lowest energy,” says Intel’s Tim Wilson, VP of the design engineering group. Picture: Intel

The opposite processor cores are distributed amongst a “Compute Tile” on Intel 4 that homes the P (Efficiency) and E (Effectivity) cores, dubbed Redwood Cove and Crestmont, respectively, plus a separate Graphics Tile on TSMC N5.

Realistically, most individuals utilizing a pc will invoke the Compute Tile, however Intel desires to warmth up the chip as little as it may, with an enhanced “Thread Director” that solely pushes work to higher-power cores after it’s tried the lowest-power ones first:

That goes for the AI coprocessor, too — which Home windows can natively see and monitor within the Job Supervisor, by the best way.

Since “Media” is separated from “Graphics,” built-in encoding and decoding of video might theoretically occur with out hitting the graphics tile in any respect. “An instance of that is the addition of {hardware} help for the AV1 movie grain function, which was beforehand executed with GPU shaders,” writes Intel.

Along with AV1 video, native HDMI 2.1 and DisplayPort 2.1 help, and both 8K HDR video or as much as 4 4K displays without delay, that SoC tile affords Bluetooth 5.4 and Wi-Fi 7. The latter theoretically affords as much as 5.76Gbps switch speeds, assuming you handle to arrange a 320MHz channel in your office or neighborhood.

Can it sport?

However all these “graphics”-like duties separate from GPU doesn’t imply the GPU is only for present. Intel says Meteor Lake can add its Intel Arc graphics — now with devoted ray-tracing items and as much as 8 Xe cores on the chip itself.

Intel says the “Xe LPG” GPU affords as much as twice the efficiency per watt of Xe LP, which themselves had been twice the efficiency per watt of its eleventh Gen Intel UHD that got here built-in in processors earlier than.

In addition they help Intel’s XeSS — its clever upscaler akin to Nvidia’s DLSS and AMD’s FSR — for the primary time on built-in graphics, which might assist increase body charges much more.

Whereas it didn’t present any efficiency numbers, Intel says the GPU can “run at a a lot decrease minimal voltage and attain a a lot increased most clock velocity” than earlier iGPUs, at effectively over 2GHz.

There’s nothing like labeled axes. Extra corporations ought to strive them! Picture: Intel

And Intel has developed its personal “patented low-cost vapor chamber” cooling answer, the corporate claims, to assist get gamer and creator laptops with Meteor Lake out on this planet.

Simply know that not each Meteor Lake / Core Extremely processor will get the flamboyant GPU. The nice print reads: “Intel Arc graphics solely out there on choose MTL processor-powered techniques with dual-channel reminiscence.”

AI assured?

However the NPU — that AI coprocessor — ought to theoretically be in each chip. “The NPU will probably be out there throughout the total product stack of Meteor Lake,” says Intel’s Tim Wilson, VP of structure.

(That will line up with what Intel CEO Pat Gelsinger stated on a July earnings name: “We’re going to construct AI into each platform we construct.” However I haven’t confirmed if Meteor Lake will seem exterior Core Extremely, so shopping for a non-Extremely chip could imply no NPU for now.)

Intel isn’t suggesting the tiny NPU will abruptly imply generative AI can cease working on big cloud servers stuffed with Nvidia H100 chips, neither is the corporate saying this one NPU can do all of it whilst you sleep. As a substitute, it’s suggesting that you just now have choices — it’s far more environment friendly to let the NPU run picture generator Steady Diffusion, and it’s quicker and nonetheless decently extra environment friendly to have your GPU and NPU run it collectively:

The corporate didn’t appear to have loads of particular examples for the way “AI goes to reinvent the way you do every thing on Home windows,” to borrow a phrase from Microsoft’s out-the-door Home windows boss Panos Panay — at the least past the identical issues Qualcomm’s NPUs can already do with Home windows Studio Results in Microsoft Groups.

However it does have an OpenVINO Inference Engine to assist speak to these purposes and pipe them on to the NPU, and loads of basic concepts, together with:

Intel is utilizing Meteor Lake as proof that it’s executing once more, as a part of Gelsinger’s grand turnaround plan for the corporate. The corporate says yields of the Intel 4 elements of Meteor Lake (learn: the Compute Tile) outstrip not solely its introductions of 14nm with Broadwell and 10nm with Ice Lake but additionally its “tock” refinements to the “tick tock” formulation with Skylake and Tiger Lake, respectively.

None of this issues if the elements don’t really carry out, and Intel’s stated nothing about uncooked efficiency or battery life in response to our questions. Reps repeatedly apologized on a convention name, saying they’d reply these types of questions nearer to launch. On the CPU aspect, the one hints I noticed had been that the brand new Crestmont E-cores have unspecified “IPC features over earlier E-cores” — although outcomes could differ, the nice print warns — and that the brand new Redwood Cove P-cores have “improved efficiency effectivity.”

However Intel says it’s investing huge on this mannequin of the long run. It’s placing $3.5 billion into New Mexico via subsequent yr and $7 billion into Penang, Malaysia, over the following 10 years to spend money on a “sharp ramp in capability” for Meteor Lake and different Foveros-style chips — those that three-dimensionally stack and assemble completely different constructing block chips onto a single bundle. Subsequent, it’s shifting to direct copper-to-copper bonding, one thing it’s calling Foveros Direct, and it intends to take a seat these chips on glass by the tip of the last decade.
