Intel Meteor Lake CPUs Will Come in GT2 ’64 EU’ and GT3 ‘128 EU’ Xe Tiled-GPU Flavors

The Intel Meteor Lake CPU will come with a ‘Tiled-GPU’ tGPU design in two flavors that will be used primarily by the next-generation mobility stack due in 2023.

Intel Meteor Lake Mobility CPUs come with two iGPU flavors: GT2 ’64 EU’ and GT3 ‘128 EU’ Xe GPUs.

The latest information comes from @tweet Which mentioned two variants of Meteor Lake’s tGPU design, one is the GT2 SKU and the other is the higher end GT3 SKU. The GT2 SKU will be offered in the standard configuration and will feature a total of 64 EUs or 512 ALU while the higher end GT3 SKU will feature 128 EUs for a total of 1024 ALU.

The GT3 SKU features the same amount of EU as the Arc A380 graphics card which has 8 Xe cores while the GT2 SKU features fewer SKUs than most entry-level desktop SKUs, the Intel Arc A310 which features 6 Xe cores. The EU 64 configuration indicates that 4 Xe cores are enabled for this particular SKU.

Now, these integrated GPUs, or tGPUs (Tiled-GPUs) as Intel calls them aren’t going to reach the same performance potential as the desktop flavors due to the limited power and lower clocks, but they will definitely be a huge performance jump that Intel has to put in in a very competitive space against AMD’s integrated RDNA 3 offerings on the Ryzen 7000 mobility stack. A rumor recently pointed to a total of 4 Xe cores or 64 EU on the Meteor Lake-S desktop lineup as well but there are rumors that the CPU stack may have been Canceled, but those were already using GT2 integrated GPUs like all other Intel desktop chips before it.

We’ve seen leaked PCI identifiers before which confirm that the majority of the Intel Meteor Lake-P CPU range uses the GT2 GPU configuration so we’ll likely see some high-end chips with the GT3 configuration (via @miktdt)

  • PCI_DID_INTEL_MTL_P_GT2_1,”MeteorLake-P GT2
  • PCI_DID_INTEL_MTL_P_GT2_2,”MeteorLake-P GT2
  • PCI_DID_INTEL_MTL_P_GT2_3,”MeteorLake-P GT2
  • PCI_DID_INTEL_MTL_P_GT2_4,”Meteorlake-P GT2

The Intel Meteor Lake Mobility CPU family is expected to debut in the second half of 2023 and will be based on ‘Intel 4’ process node for Compute Tile & TSMC’s 5nm Tile GPU.
