South Korean tech treasure hunter Coelacanth’s Dream (opens in new tab) has dug up some interesting information about the integrated GPU that comes with Intel’s Meteor Lake processors. From sightings of new code patches for the Intel Graphics Compiler (IGC), the fishy tech poster has revealed that Meteor Lake iGPUs could have ray tracing support in hardware. Unfortunately, a potential negative is that the iGPU may lack Intel XMX (Xe Matrix eXtension) units.

Intel’s 13th Gen Core processors, codenamed Raptor Lake (RPL), are next up – and due quite imminently. However, in 2023, we think Intel’s 14th Gen Core processors, dubbed Meteor Lake (MTL), will cause quite a stir with several bold, advanced steps taken. Regular readers will know that the transition from 13th to 14th Gen Core processors will move from Intel 7 to Intel 4. That isn’t all, though, as we will see Intel’s first disaggregated design with a TSMC N3 tile under the heat spreader. It will be the GPU portion of the chip, and thanks to detective work from people like Coelacanth’s Dream, we have an ever-growing clearer picture of this iGPU.

In July this year, Coelacanth’s Dream discovered some Intel Linux patches, which suggested MTL’s graphics tile would feature the Xe-HPG/Xe-LPG architecture and up to 128 EUs produced by TSMC using its N3 fabrication process. Now we have sight of the new code patches for the Intel Graphics Compiler (opens in new tab)(IGC), some more deductions can be made regarding the GPU tile.

Probably most interesting is the patch indicator that suggests Meteor Lake’s iGPU will have ray tracing hardware. Intel LGA1700 CPUs, like Alder Lake and Raptor Lake, come with up to 96 Xe-LP EUs. However, Meteor Lake will have a Xe-HPG architecture GPU with more in common with the Alchemist / DG2 discrete graphics cards and might feature up to 128 or even 192 of these EUs. The ray tracing support feature was picked up in IGC, where it sets ray tracing support to enabled if iGFX_meteorlake is detected. Moreover, Meteor Lake also seems to support hardware ray tracing in any app that helps the feature in Alchemist / DG2 or Ponte Vecchio.
