Intel Meteor Lake has two versions of GT2 and GT3

The structure of Intel’s 14th-generation Core processor Meteor Lake will undergo major changes, from the previous single-chip design to multi-chip, and use Foveros 3D packaging technology to seal these chips together. The CPU includes four modules in total, including the CPU module, GPU module, SOC module, and IO module. Among them, the CPU module adopts Intel 4 process, while the SOC and IO modules adopt TSMC 6nm process, and the GPU module adopts TSMC 5nm process. The modules are mounted on a passive mid-level that uses Intel’s 22FFL process.

According to the information provided by @Kepler_L2, the GPU module of Intel Meteor Lake will have two versions, one is GT2 and the other is a more advanced GT3. Among them, the GT2 module is used on the standard version of the processor, with 64 EUs and 512 ALUs in total, while the GT3 module is used on the high-end CPU, with a total of 128 EUs and a total of 1024 ALUs.
