Intel Meteor Lake CPUs with TGPU reportedly support ray tracing, motion FP64 computing, but lack XMX units

In a new commit published on GitHub, Intel may have confirmed ray tracing support for Meteor Lake CPUs with Xe-HPG TGPUs. Intel’s 14th Gen Meteor Lake CPUs are scheduled for release in 2023 and will feature a host of new features, including new hybrid cores, integrated graphics using a tiled design, and the VPU accelerator we talked about in our last report.

Intel Meteor Lake CPUs with TGPU designs reportedly support ray tracing and FP64, but lack XMX units

According to a detailed report published by Coelacanth-Dream, it looks like the GPUs on Intel Meteor Lake CPUs are detected as Xe-HPG products in the IGC (Intel Graphics Compiler). With that in mind, we can assume it will use the same architecture as the existing DG2 or Alchemist GPUs, but that’s not quite the case.

Meteor Lake GPU (also known as tGPU (Tiled-GPU)) does not support DPAS (dot-accumulate systolic) instructions executed through XMX units, as it is reported to be not equipped with these instructions. In a previous report, we covered how Intel’s Meteor Lake CPU’s graphics unit lacks XMX, resulting in lower feature-level support for technologies like XeSS, but it will offer partial FP64 support, which Intel iGPUs have had over the past few years. Missing generations.

A more interesting detail is that the TGPU (Xe-MTL) on Intel’s Meteor Lake CPUs will reportedly offer hardware-level ray tracing support. The TGPU is said to offer the same level of ray tracing support as the Alchemist and Ponte Vecchio GPUs, as the design hasn’t changed, at least as far as ray tracing is concerned.

About support for hardware ray tracing Meteor Lake GPUIGC/AdaptorCommon/RayTracing/PrologueShaders.cpp itIGFX_METEORLAKE Believe they support it because .

Besides that, in the part of the code that determines his hardware ray tracing support, it seems Meteor Lake GPU support it as well Alchemist/DG2 and Laoqiao Because there is no change.

Intel’s Meteor Lake CPU tiled GPU won’t be the first integrated graphics chip to support ray tracing. For almost a year now, AMD has released Ryzen 6000 “Rembrandt” APUs with RDNA 2 iGPUs. This will be Intel’s first integrated graphics card to support ray tracing, but we’d like to add some XeSS or AI-level upsampling support.As we’ve seen with AMD’s APUs, things like FSR 2.0 can really help deliver playable FPS in games This is really great for mobile gamers.
