Intel Panther Lake Gets Ready To Roar With Third-Gen Xe3 Celestial GPU Architecture
That next generation will be called Xe2, and it will go into the Battlemage discrete GPUs as well as the Lunar Lake integrated graphics. That means that the upcoming Meteor Lake and Arrow Lake CPUs will be using integrated graphics based on the first-gen Xe-LPG. The third-generation, or Xe3, will show up in the third-generation Arc GPUs known as "Celestial," and apparently also in the integrated graphics for "Panther Lake", which is expected to come after Lunar Lake.

This information comes to us from a rather curious source: a LinkedIn profile for an unnamed Intel engineer. The leak was spotted by the sharp-eyed 포시포시, better known as @harukaze5719 in the English-speaking world. There's not a lot of new information here, but the double confirmations that Arrow Lake will still be using Xe-LPG, as well as the existence of Panther Lake, are pretty interesting in their own rights.
Obviously, these graphics architectures will find their way into enterprise and datacenter parts as well; it's known that Falcon Shores will have compute tiles based on Xe2 (likely HP or HPG), and it's probable that the recently-mentioned Melville Sound will likewise be based on Xe2 in some capacity.

Of course, this is all quite far in the future. Intel is expected to launch a refresh of Raptor Lake this year, alongside some portion of Meteor Lake CPUs, primarily for mobile, and also a possible refresh or new release of mid-range Arc Alchemist GPUs. We won't see Arrow Lake or Battlemage until next year at the earliest, which means Celestial and Panther Lake are probably 2026 products at the absolute earliest.
