in a new commit posted on GitHubIntel may have confirmed ray tracing support with Xe-HPG TGPU for Meteor Lake CPUs. this Intel 14th Gen Meteor Lake CPUs It’s scheduled to launch in 2023 and will come with a host of new features, including brand new hybrid cores, integrated graphics using tiled designs, and a VPU accelerator. final coverage.
TGPU-Designed Intel Meteor Lake CPUs Reported to Come With Ray Tracing and FP64 Support, But No XMX Units
According to a detailed report published by Coelacanth-DreamIt appears that the GPU in Intel Meteor Lake CPUs is detected as an Xe-HPG product in IGC (Intel Graphics Compiler). With that in mind, we can assume it will use the same architecture as current DG2 or Alchemist GPUs, but that’s not entirely the case.
Meteor Lake GPU, also known as tGPU (Tiled-GPU), does not support DPAS (Dot Product Accumulate Systolic) instructions executed via XMX units because it is reportedly not equipped with them. Inside previous reportWe’ve discussed how the graphics unit of Intel’s Meteor Lake CPU will lack XMX and this will provide lower feature level support for technologies like XeSS but will instead have partial FP64 support that has been missing from Intel iGPUs for the past few generations.
The more interesting detail is that the TGPU (Xe-MTL) in Intel Meteor Lake CPUs will reportedly come with 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 there is no change in design, at least in terms of ray tracing.
Regarding HW ray tracing support Meteor Lake GPUs
IGFX_METEORLAKEIt is thought that they are supported because of the addition.
Other than that, in the code part that determines the HW ray tracing support, it seems Meteor Lake GPU it also supports Chemist / DG2 and Ponte Vecchio because there is no change.
Intel’s Meteor Lake CPU tiled GPU won’t be the first integrated graphics chip to offer ray tracing support. AMD has been offering this for almost a year with their Ryzen 6000 “Rembrandt” APUs with RDNA 2 iGPUs. This will be Intel’s first ray-traced integrated graphics, but we hope some partial XeSS or AI-level sampling support is added. As we’ve seen in AMD’s APUs, technologies like FSR 2.0 can really help provide playable FPS in game titles and that would be really cool for mobile gamers.
