Meteor Lake, the first-generation “Core Extremely” processors, can be Intel’s first “disaggregated” or chiplet-based CPUs. The launch of those essential chips is lower than a month away, and Intel is constant to drip-feed particulars to the press and the general public. The most recent information comes from a video posted to the “Intel Know-how” YouTube channel, the place Tom “TAP” Petersen explains how Intel achieved double the graphics performance-per-watt in Meteor Lake.
That double comparability is in opposition to Alder Lake, not in opposition to Raptor Lake, however the graphics subsystems of these processors are basically the identical. TAP factors out that Intel achieved these good points via enhancements in three key areas: clock charges, structure, and easily making a much bigger GPU. A cynic may level out that that is merely the way you make a sooner GPU, however there are just a few fascinating particulars within the video.
Foremost amongst them is early within the video the place TAP explains that the disaggregated nature of Meteor Lake permits Intel to do fascinating issues with the construction of the built-in GPU. A graphics processor is usually composed of three components: a graphics engine that handles 3D duties, a show engine that handles output composition, and a media engine that takes care of video encoding and decoding.
TAP explaining the three areas that Intel improved to realize 100% in graphics efficiency.
Because it occurs, the media engine on Meteor Lake is definitely on the processor’s SoC tile. Which means that the processor can energy down the GPU tile that accommodates the graphics and show engines even when the person is watching a video. That might drastically enhance the battery lifetime of Meteor Lake laptops when used to observe movies.
Petersen explains that the Meteor Lake iGPU will get a few of its efficiency enhancements from greater clocks that come as the results of each design optimizations (to permit for greater clocks) in addition to a die shrink compared to Alder Lake. The GPU tiles for Meteor Lake are fabricated at TSMC on that firm’s N5 course of, and that enables for each decrease minimal voltage in addition to a better clock charge on the identical time, in comparison with the Xe-LP graphics in Alder Lake.
The opposite enhancements come from architectural modifications in Xe-LPG over Xe-LP and from the straightforward indisputable fact that it is a 33% bigger GPU compared to Alder Lake. Meteor Lake’s greatest GPU configuration, which can be branded as Arc Graphics, features a pretty beefy GPU with two Xe-LPG slices, every containing 4 Xe cores totaling 128 Xe Vector Engines with a complete of 1024 shaders, 64 texture items, and 32 ROPs. That is basically the identical variety of graphics sources as present in a GeForce GTX 1650 Ti or Radeon RX 6500 XT.
Intel’s upcoming Meteor Lake processors are lower than a month away from launch, so it is no shock that the corporate is divulging further particulars about how the brand new components will work. In its personal phrases, Intel says that Meteor Lake is its “largest shift in shopper SoCs in 40 years.” We’re intensely curious to get our arms on a system sporting one of many new CPUs, and as quickly as we do, you will know the whole lot we will glean from it. So keep tuned.
