Intel Meteor Lake CPUs With TGPU Reportedly Features Ray Tracing Support, Sports FP64 Compute But Lacks XMX Units


In a new commit published on GitHub, Intel may have confirmed ray tracing support for their Meteor Lake CPUs with Xe-HPG TGPU. The Intel 14th Gen Meteor Lake CPUs are slated for release in 2023 and will ship with a range of new features, including brand new hybrid cores, integrated graphics using tile designs, and a VPU accelerator which we mentioned in our latest coverage. had about.

Intel Meteor Lake CPUs with TGPU design reportedly ship with Ray Tracing and FP64 support, but lack XMX units

According to a detailed report published by Coelacanth-Dream, it appears that the GPU on the Intel Meteor Lake CPUs is detected as a Xe-HPG product within IGC (Intel Graphics Compiler). Given that, we can assume it will use the same architecture as the existing DG2 or Alchemist GPUs, but that’s not quite the case.

The Meteor Lake GPU, also known as tGPU (Tiled-GPU), does not support DPAS (Dot Product Accumulate Systolic) instructions executing through the XMX units, as it is reportedly not equipped with them. In a previous report, we discussed how the graphics unit of Intel’s Meteor Lake CPU would lack XMX, resulting in lower feature-level support for technologies like XeSS, but instead it will offer partial FP64 support, something that has been happening for the past few years. was missing in Intel iGPU’s generations.

The more interesting detail is that the TGPU (Xe-MTL) on the 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 Alchemist and Ponte Vecchio GPUs, as there is no design change, at least as far as ray tracing goes.

Other than that, in the code section that defines its HW ray tracing support, it looks like: Meteor Lake GPU supports it too Alchemist / DG2 and Ponte Vechio because there is no change.

Intel’s Meteor Lake CPU tiled-GPU won’t be the first integrated graphics chip to support ray tracing. AMD has been offering it for almost a year now with their Ryzen 6000 “Rembrandt” APUs with RDNA 2 iGPUs. This will be Intel’s first integrated graphics with ray-tracing, but we hope to add partial support for XeSS or AI-level upsampling. As we have seen with AMD’s APUs, technologies such as: FSR 2.0 can really help deliver playable FPS in game titles and that would be really great for mobile gamers.

Intel Meteor Lake Mobility CPU Lineup Expected Features:

  • Triple-hybrid CPU architecture (P/E/LP-E cores)
  • Brand new Redwood Cove (P-Cores)
  • Brand new Crestmont (E-Cores)
  • Up to 14 cores (6+8) for H/P series & up to 12 cores (4+8) for U-series CPUs
  • Intel 4 process node for CPU, TSMC for tGPU
  • Intel ‘Xe-MTL’ GPU with up to 192/128 EUs
  • Up to LPDDR5X-7467 & DDR5-5200 support
  • Up to 96 GB DDR5 & 64 GB LPDDR5X capacities
  • Intel VPU for AI Inference with Atom Cores
  • x8 Gen 5 lanes for discrete GPU (H series only)
  • Triple x4 M.2 Gen 4 SSD support
  • Four Thunderbolt 4 ports

The Intel 14th Gen Meteor Lake CPUs are expected to launch in the second half of 2023 and will use the “Intel 4” process node along with a large number of third-party IP/process nodes for the rest of the tiles. Expect more information on Meteor Lake CPUs at Hot Chips 34.
