In a new commitment published on howIntel may have confirmed ray tracing support for its Meteor Lake processors with its Xe-HPG TGPU. The 14th Generation Intel Meteor Lake processors The launch is scheduled for 2023 and will come with a host of new features, including brand 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 have ray tracing and FP64 support, but lack XMX modules
According to a detailed report published by Dream of KoalakanthIt appears that the GPU in Intel Meteor Lake processors was detected as an Xe-HPG product in the Intel Graphics Compiler (IGC). That said, we can assume it will use the same architecture as existing DG2 or Alchemist GPUs, but that’s not entirely true.
The Meteor Lake GPU, also known as tGPU (Tiled-GPU), does not support Dot Product Accumulate Systolic (DPAS) instructions executed by XMX drives, as they would not be equipped with them. in previous relationshipWe showed 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 should have support for 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 support for HW ray tracing is active Meteor Lake GPU
IGC/AdaptorCommon/RayTracing/PrologueShaders.cppthis isIGFX_METEORLAKEThey are believed to support it due to the addition.Aside from that, in the part of the code that defines the device’s ray tracing support, it looks like Meteor Lake graphic map supported by Chemistry / DG2 And Vichyo bridge Because there is no change.
The Intel Meteor Lake processor’s tiled GPU won’t be the first integrated graphics chip to support ray tracing. AMD has been introducing it for nearly a year with “Rembrandt” Ryzen 6000 APUs equipped with RDNA 2 iGPUs. Partial loading or XeSS 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 great for mobile gamers.
Expected features of the Intel Meteor Lake Mobility line of processors:
- Triple hybrid processor architecture (P / E / LP-E core)
- Brand new Redwood Cove (P-Core)
- Brand new Crestmont (E-Core)
- Up to 14 cores (6 + 8) for H / P series and up to 12 cores (4 + 8) for U series processors
- Intel Compute Node 4 for CPU, TSMC for tGPU
- Intel “Xe-MTL” GPU up to 192/128 EU
- It supports up to LPDDR5X-7467 and DDR5-5200
- Capacities 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 launch by the second half of 2023 and will use an “Intel 4” process node along with a pool of third-party compute nodes / IP addresses for the rest of the boxes. Expect more information on Meteor Lake Processors in Hot Chips 34.
