Intel’s Meteor Lake GPU Doubles Built-in Graphics Efficiency Per Watt

Posted on

Intel Meteor Lake will include a considerably improve built-in graphics resolution. At its Innovation occasion, Intel offered particulars on the upcoming Meteor Lake product household, which can arrive later this 12 months. Now we have a collection of articles masking the varied points of the brand new structure, which guarantees to be a radical departure from prior processors because of using Foveros chip stacking applied sciences. You’ll find the opposite articles within the checklist beneath; we’ll be specializing in the show and graphics applied sciences for this piece.

Meteor Lake Graphics Structure

Skipping all the architectural particulars for a second, Intel claims the Meteor Lake GPU will double the efficiency per watt of its earlier technology Iris Xe Graphics resolution, which was present in twelfth Gen Intel Core processors. Whereas GPUs usually lay declare to effectivity enhancements, given how energy constrained cellular graphics options can get, there’s an actual chance we might see uncooked efficiency double as properly. That is a probably big gen-over-gen enchancment, and there is loads of different particulars to dissect.

The brand new graphics structure is known as Xe-LPG, the low energy gaming various to Xe-HPG — that is the GPU discovered within the devoted Intel Arc Alchemist GPUs. It is probably double the efficiency of Xe LP, which was the graphics resolution used within the eleventh Gen Tiger Lake, twelfth Gen Alder Lake, and thirteenth Gen Raptor Lake cellular options.

Be aware additionally that the best configurations will not be accessible on all Meteor Lake processors, although the precise particulars of the decrease tier fashions have not been revealed. We might anticipate Intel to disable a few of the GPU processing clusters and maybe a few of the different further options on lesser elements, whereas the Core 5/7/9 chips will provide the whole function set.

The block diagram for Xe-LPG exhibits the utmost configuration, which can include eight Xe-Cores, 128 Vector Engines (previously referred to as Execution Models), two Geometry Pipelines, eight Samplers, 4 Pixel Backends, and eight Ray Tracing Models. These might be divided up between the 2 Render Slices, the primary constructing block for Intel Arc GPUs.

If the above diagram seems to be acquainted on a few of the particulars, that is as a result of it is successfully the identical because the ACM-G11 GPU that is used within the Intel Arc A380 — solely now it is an built-in graphics resolution. Almost the whole lot current within the A380 seems to be right here as properly, apart from GDDR6 reminiscence controllers and XMX models (extra on the latter beneath). As you’d anticipate from an built-in resolution, the Meteor Lake GPU will share system reminiscence with the CPU.

Intel hasn’t offered clock speeds or the L2 cache measurement but, however generally we might anticipate extra conservative clocks than what you will get from a devoted A380. That GPU runs at as much as 2.4 GHz, nevertheless it additionally consumes as much as 75W of energy. The cellular Iris Xe in the meantime clocked at as much as 1.5 GHz in chips just like the Core i9-13905H, with a most TDP for the whole bundle of simply 45W.

We might have a look at this a unique means, although, as Intel’s Xe DG1 graphics card mainly used the identical Xe-LP configuration because the built-in chips. It wasn’t a really potent resolution, and it is little shock that the Arc A380 simply outclassed the Xe DG1. We anticipate an analogous uplift in efficiency and capabilities going from built-in Xe-LP to built-in Xe-LPG.
