Intel Panther Lake leak hints at huge “Celestial” Xe3 GPU upgrade

Intel’s 3rd Generation Xe graphics will be integrated into the company’s Panther Lake CPUs

Thanks to a new report from Prakher Verma, as verified by Videocardz, we now know that Intel will be releasing “Panther Lake” CPUs in 2025 with Xe3 (3rd Generation Xe) graphics. Furthermore, Panther Lake CPUs will feature up to 12 Xe3 cores.

In terms of GPU core count, these specs give Intel’s Panther Lake CPUs up to 50% more CUs than today’s Meteor Lake CPUs. Combine that with two generations of GPU architectural improvements, and Panther Lake should deliver compelling levels of graphics performance.

Prakhar revealed the core counts of several Panther Lake mobile CPU configurations. These CPU configurations include P-cores, E-cores, and Low-Power e-cores. If this report is correct, Panther Lake may be Intel’s first product to release with 3rd Generation “Celestial” Xe graphics. This iGPU alone is said to feature 120 TOPS of AI performance.

Overall, Prakhar has stated that Panther Lake is 35% more efficient than Lunar Lake, which itself should be more efficient than today’s Meteor Lake processors. This should result in increased battery life and performance for Intel’s future mobile CPUs.

Panther Lake is the result of Intel’s chiplet/tile strategy

Intel’s next-generation Panther Lake CPUs will reportedly be built using silicon from both TSMC and Intel. Intel’s 18A node will be used to create Panther Lake’s main CPU cores. TSMC’s 6nm node will reportedly be used for the chips’s SoC tiles. Furthermore, TSMC’s N3 node will reportedly be used to build this chip’s integrated graphics chip. That’s three different lithography nodes on a single chip.

Before we see Panther Lake, we will need to wait for Lunar Lake and Arrow Lake to launch. Panther Lake is a 2025 CPU architecture from Intel, and Intel have not event released their new 2024 CPU lineup yet. It will be a while before Panther Lake comes to market. Even so, it promises to be an exciting launch.
