With its next generation Xe3 "Celestial" graphics architecture, Intel is returning to entry-level variants of its graphics IP that lacks features such as ray tracing, Kepler_L2 found in open source driver code supporting the integrated graphics solution of the upcoming "Wildcat Lake" mobile processor. Intel is designing "Wildcat Lake" to be its new entry-level mobile processor targeting Windows notebooks and Chromebooks priced well below the $400 mark. The iGPU of this chip, while based on the next-generation Xe3 architecture, only comes with 2 Xe cores worth 32 EU (execution units), which doesn't result in any meaningful amount of shader power to back ray traced workloads.

It might be premature to call this a true "Xe3-LP" sub-architecture at this point. While the original Xe-LP architecture powering the iGPU of "Tiger Lake," "Rocket Lake," and "Alder Lake" lacks ray tracing, it also physically lacks ray tracing units, and XMX cores for advanced matrix math acceleration driving AI workloads. It's being suggested in Kepler_L2's thread that the iGPU physically has RT units and XMX cores, but these are disabled, and are essentially deadweights on the silicon.
