Double the graphics performance per watt, Intel explains the core display part of the Meteor Lake processor in detail

In order to stimulate consumer interest in the new mobile processors, in the latest official video released by Intel, Tom Petersen, a senior engineer in the graphics department, provided a detailed introduction to the core display performance.

He stated that compared to the 12th generation Alder Lake chip (IT Home note: not the previous generation Raptor Lake), the Meteor Lake core displays twice the graphics performance per watt.

Petersen stated that the major breakthrough in Intel Meteor Lake's core display is mainly due to increased clock speed, optimized architecture, and the use of larger iGPU units.

A GPU typically consists of three parts:

Graphics engine: processing 3D images

Display module: responsible for outputting signals to the screen

Media engine: responsible for encoding and decoding videos

The iGPU media engine of Meteor Lake is actually located in the SoC chiplet, rather than the main integrated graphics unit, which can significantly reduce power consumption and extend battery life. The iGPU chiplet adopts the Xe-LPG graphics architecture, which directly handles 3D graphics, computational functions, and some AI algorithm operations.

The graphics architecture of Xe-LPG is basically the same as that of Xe-HPG (the architecture used in the 12th/13th generation CPU core display), but it lacks the XMX hardware matrix engine. Xe-LPG retains support for general DP4a shader instructions and can support XeSS sampling technology.Petersen also explained that the Meteor Lake integrated graphics card achieved performance improvement by increasing the operating frequency of the graphics core, not only due to the overall optimization of the integrated graphics card structure, but also due to the transition to new technology programs. The integrated graphics microchip of the Meteor Lake processor is manufactured using TSMC N5 technology. Compared to the Xe-LP graphics card of the Alder Lake processor, it is optimized for both lower operating voltage and higher clock speed.（From IT home）
