In a new commitment published on asIntel may have confirmed ray tracing support for its Meteor Lake processors with its Xe-HPG TGPU. The 14th Generation Intel Meteor Lake processors It’s slated to launch 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 on our site. 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 Koalakanth DreamIt 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 previous reportWe’ve shown 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 is expected to 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 are no design changes, at least when it comes to ray tracing.
About HW ray tracing support is on Meteor Lake GPU
IGC/AdaptorCommon/RayTracing/PrologueShaders.cppthis isIGFX_METEORLAKEIt is believed that they support it because of the addition.Other than that, in the part of the code that defines device ray tracing support, it looks like Graphic map of Meteor Lake supported by Chem/DG2 And 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 Meteor Lake processors in Hot Chips 34.
