Arrow Lake will also have mobile SoC. Lunar Lake will only cover the low power mobile segment. Arrow Lake will cover everything else.

Furthermore, iGPU and CPU tiles are separated now, so they can replace the iGPU tile or take it out entirely if they want. My guess is Desktop SoC will have a gimped iGPU version.

Article is old btw. Meteor Lake iGPU does support XeSS. Intel posted a demonstration on Youtube.
