New Intel Panther Lake leak highlights 45 W TDP for top-spec variant

YouTuber Moore's Law is Dead has revealed what Intel has in store for laptops with the Panther Lake platform. The latest leak says Intel's top-spec Panther Lake-H chip will come with 4 Cougar Cove performance cores, 8 Darkmont efficiency cores, and 4 Darkmont LPE cores.

Its CPU tile will be made on Intel 18A, the GPU die on TSMC N3E, and the Platform Control Die on TSMC N6. On the GPU side, Panther Lake was tipped to arrive with up to a 12 EU iGPU based on Intel's Celestial architecture.

This is at odds with a leak from last year, which predicted a total of five Panther Lake CPUs with the top-spec model tipped to arrive with 6 P-cores, 8 E-cores and 4 LPE cores. Then again, the same leak stated that the two SKUs with 6 P-cores were further behind in development than the aforementioned SKU with 4 P-cores.

The leak adds that Panther Lake's LPE cores will actually be usable by applications this time, something that wasn't possible in previous generations. Moore's Law is dead estimates a 5-13% IPC increase, but states it has been challenging to predict IPC uplift in recent Intel CPUs.

The top-spec Panther Lake SKU will have a maximum TDP of up to 45 Watts, which is slightly higher than the Core Ultra 9 288V's 30 Watts. Additionally, it might be possible to push other (non-Core Ultra 9) SKUs to that figure, something that wasn't possible with Lunar Lake.
