It has been a few weeks since Intel announced the upcoming 14th Gen Core series which will come with a “Versatile Processing Unit” for AI and inference. Intel has now shed some light on the integrated graphics architecture. The Meteor Lake CPUs will feature the Xe-LPG graphics which is a derivate from the Xe-HPG. The changes that have been made to the architecture include no support for the DPAS (Dot Product Accumulate Systolic) function.
Some recent patches introduced to the Intel Graphics Compiler suggest that Meteor Lake’s iGPU may come with ray tracing acceleration support. This allows us to check whether or not the architecture is a derivate of DG2 or not, which Meteor Lake is rumored to be. If this is proven correct, then Meteor Lake is coming with ray tracing support.
It is important to note here that raytracing hardware acceleration isn’t entirely a new thing when it comes to integrated graphics. At the start of the year, AMD launched its Ryzen 7000 series CPUs which were based on the RDNA2 architecture and came with dedicated Ray Accelerator units.
We are yet to see exactly how many Execution Units will be featured on the Xe-LPG architecture. Some renders from Intel show 192 Execution Units but there are rumors that this number might change.
