Intel Panther Lake and Beast Lake leak suggests up to 40% more single-core performance vs Arrow Lake for former and Extra Big cores for latter

Intel has confirmed in the past that after launching Meteor Lake and Arrow Lake processors through 2024, the company will move on to Lunar Lake and beyond. Back in March, we reported that Panther Lake could be the architecture to follow up Lunar Lake with an Xe3-LPG iGPU in tow. Now, in addition to leaking a plethora of details regarding the Meteor Lake and Arrow Lake CPUs, Tom from Moore’s Law Is Dead has alleged some details about Intel Panther Lake and Beast Lake CPU architectures.

Before we move on to discuss the leak, it is important to remember that Panther Lake and Beast Lake, if real, are potentially years away from being released. Therefore, MLID’s information is extremely early and should be taken with a grain of salt.

Intel Panther Lake

Tom suggests that Intel is currently planning to launch the Panther Lake chips in late 2025 for LGA1851, the same platform as Arrow Lake. interestingly, the leaker claims that Panther Lake was almost canceled due to the supposedly little IPC gain of around 10% vs Arrow Lake in simulations but, thanks to the emergence of the “Cougar Cove” P-cores for the 40-core (8 P-cores + 32 E-cores) PNL CPU, Panther Lake is expected to outperform the 40-core ARL processor by 30-40% in single-threaded and 15-20% in multi-threaded applications.

The leaker further reports that Intel is canning several projects and redistributing resources to make sure ARL beats AMD Ryzen CPUs in all metrics and to ensure that Panther Lake also impresses.

Intel Beast Lake

Tom also shares that he has heard about the existence of “Beast Lake” which is in early development. Per the leaker, Beast Lake’s main focus is single-threaded performance. Beast Lake chips could see “Extra Big Cores” and/or get more than 8 P-cores for the top-of-the-line desktop chip.

Finally, Intel seems to be developing two Beast Lake designs, one with only 10-Extra Big cores and the other with 4-Extra Big cores and 32-Little cores with the latter 36-core design supposedly being the “lead” one.

As we’ve mentioned above, this is very early information and it will be a while before Intel officially unveils its future CPU architectures. Therefore, exercise caution and don’t take MLID’s leak as final.
