Intel Meteor Lake processors with TGPU are said to support ray tracing, FP64 sports computing but lack XMX modules

In a new commitment posted on GitHub, Intel may have confirmed ray tracing support for its Meteor Lake processors with the Xe-HPG TGPU. The 14th generation Intel Meteor Lake processors are slated for release in 2023 and will come with a bunch of new features, including all-new hybrid cores, integrated graphics using tiled designs, and the VPU accelerator we talked about in our last cover.

Intel Meteor Lake processors with a TGPU design are said to come with ray tracing and FP64 support, but they lack the XMX modules

According to a detailed report published by Kolakanth Dream, it appears that the GPU in Intel Meteor Lake processors has been detected as an Xe-HPG product in the IGC (Intel Graphics Compiler). Given this, we can assume that it will use the same architecture as the existing DG2 or Alchemist GPUs, but this is not entirely the case.

The Meteor Lake GPU, also known as a tGPU (Tiled-GPU), does not support Dot Product Accumulate Systolic (DPAS) instructions executed by XMX units, as they would not be equipped with them. In the previous report, we explained how the Intel Meteor Lake CPU will lack XMX, resulting in lower feature-level support for technologies like XeSS, but will instead feature partial FP64 support, which has been missing in Intel iGPUs for a few generations.

The most interesting detail is that the TGPU (Xe-MTL) on Intel Meteor Lake processors must be compatible with hardware-level ray tracing. The TGPU is said to offer the same level of ray tracing support as the Alchemist and Ponte Vecchio GPUs, as there are no design changes, at least when it comes to ray tracing.

About HW ray tracing support is on Meteor Lake GPUIGC/AdaptorCommon/RayTracing/PrologueShaders.cpp this isIGFX_METEORLAKE It is believed that they support it because of the addition.

Regardless, in the part of the code that specifies its support for HW ray tracing, it appears that Graphic map of Meteor Lake supported by Chem/DG2 And the Vichyo Bridge Because there is no change.

The tiled GPU of the Intel Meteor Lake processor will not be the first integrated graphics chip to support ray tracing. AMD has been introducing it for nearly a year now with Ryzen 6000 “Rembrandt” APUs featuring RDNA 2 iGPUs. XeSS partial loading or sampling will be added at the AI ​​level. As we’ve seen with AMD’s APUs, technologies like FSR 2.0 can really help deliver playable FPS in gaming titles And it would be really cool for mobile gamers.

Expected features of the Intel Meteor Lake Mobility processor line:

  • Triple hybrid processor 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 and up to 12 cores (4 + 8) for U series processors
  • Intel 4 Processing Node for CPU, TSMC for tGPU
  • Intel ‘Xe-MTL’ GPU with up to 192/128 EU
  • Support up to LPDDR5X-7467 and DDR5-5200
  • Capacity up to 96GB DDR5 and 64GB LPDDR5X
  • Intel VPU for AI inference using Atom cores
  • x8 Gen 5 discrete GPU lanes (H series only)
  • Support for three M.2 Gen 4 x4 hard drives
  • Four Thunderbolt 4 ports

The 14th generation Intel Meteor Lake processors are expected to be launched by the second half of 2023 and will use an “Intel 4” process node along with a pool of third-party processing nodes/IP addresses for the rest of the boxes. Expect more information about the Meteor Lake processors in Hot Chips 34.
