A “Celestial” Xe3 iGPU Will Be Integrated Into an Intel “Panther Lake” CPU.

The microarchitecture powering Intel’s 17th Gen Core CPUs, which are scheduled to launch in 2026–2027, is known as “Panther Lake” under development. It replaces the 16th Gen (“Lunar Lake”), 15th Gen (“Arrow Lake”), and 14th Gen (“Meteor Lake”) architectures (2025–2026). While there isn’t much information available about “Panther Lake,” the first piece of information found on the LinkedIn profile page of an Intel Graphics engineer suggests that the processor will include an iGPU based on the Xe3 “Celestial” graphics architecture, which is two generations ahead of the current Xe “Alchemist” and one generation ahead of the Xe2 “Battlemage” graphics architecture.

With variations extending from small client discrete GPUs to very big HPC-AI processors, Intel’s graphics architectures will continue to be highly scalable and adaptable in their applications. Xe3-LPG, a heavily condensed version of the architecture for lower Xe Core counts, will be the variant for the iGPU powering “Panther Lake.” It has the ideal hardware to run in power-constrained devices like mobile processors. According to an older company slide describing the scalability of “Celestial,” Intel will continue to use the disaggregated chiplet design for its processor designs down to “Panther Lake,” as it emphasized a “next platform” processor succeeding “Meteor Lake” and its immediate successor (“Arrow Lake”).
