Intel Panther Lake-H High-End Laptop CPU Spotted With 12 Next-Gen Xe3-LPG “Celestial” GPU Cores

Intel's next-gen Panther Lake-H CPUs for laptops have been spotted with up to 12 Xe cores based on the upcoming Celestial "Xe-LPG" architecture.

The information comes from within the shipping manifestos spotted by @miktdt and shows the Intel Panther Lake-H CPUs along with possible specifications. These chips should be very early samples since Panther Lake has already been in the fabs since early Q2 and Intel could be receiving and sampling the first chips for early evaluation purposes.

Coming to the details, the Intel Panther Lake CPU here is listed as an "H" SKU which represents the high-end laptop segment. This chip is also listed with 12 Xe cores and a new "GG3-CT" label which could be a reference to the 3rd Generation Arc graphics architecture codenamed Celestial.

What's interesting here is that the Panther Lake-H CPU is listed with 12 Xe cores which are 50% more cores versus the 8 Xe-cores currently featured on Meteor Lake chips and should remain the same on the upcoming Arrow Lake CPUs. Intel's Lunar Lake CPUs are also going to use the next-gen "Xe2-LPG" GPU cores based on the Arc Battlemage architecture.

Intel's Celestial "Xe3-LPG" graphics architecture should be a huge upgrade over current Alchemist & even the upcoming Battlemage GPUs. Having 50% more cores is going to deliver much faster iGPU performance and we can also expect the use of new memory types to help boost the bandwidth. It is expected that 2025 will be the year of the LPDDR6 and faster LPDDR5X standards & that should definitely help.

Last month, Intel confirmed that its Panther Lake CPUs were already in fabs and are on track for a mid-2025 launch. Based on the information we have right now, these chips will utilize the Cougar Cove P-Core architecture and the Skymont E-Core architecture. They will be housing an advanced NPU which will deliver 2x the AI TOPs versus Lunar Lake which itself is expected to offer over 100 platform AI TOPs. Intel is also expected to utilize its Intel 3 process node for the SOC tile while the iGPU tile is expected to be fabricated using an external node from TSMC, most likely N3 or N3.

The IDs for Intel's next-gen Panther Lake CPUs were recently spotted in CoreBoot which pointed out GT3 and GT3 tier graphics chips, more on that here.
