Panther Lake: Leak reveals clocks of up to 5.1GHz for Intel Core Ultra Series 3 CPUs

We are getting closer and closer to the arrival of the first products equipped with Panther Lake processors, based on Intel’s 18A manufacturing process. So, this time we had the complete leak of the clocks for each of the models that will be available at the debut of the so-called Intel Core Ultra Series 3.

The information comes from well-known insider @jaykihn0, who has a great track record of success. Still, it is still an unofficial rumor and should be treated as such. According to the leaker, the most advanced products in the series will reach up to 5.1GHz in boost clock:

• Core Ultra X9 388H: up to 5.1GHz
• Core Ultra X7 368H: até 5,0GHz
• Core Ultra X7 358H: até 4,8GHz

The rest of the list features processors with different nomenclatures than what has appeared in previous leaks for Panther Lake, so we will reproduce according to the insider’s post.

Configuration 4 P-Cores + 8 E-Cores + 4 LPE-Cores:

• Core Ultra 386H: até 4,9GHz
• Core Ultra 366H: até 4,8GHz
• Core Ultra 356H: até 4,7GHz

4+4+4 configuration:

• Core Ultra 5 338H: até 4,7GHz
• Core Ultra 336H: até 4,6GHz

4+0+4 configuration:

• Core Ultra 365: up to 4.8GHz
• Core Ultra 355: até 4,7GHz
• Core Ultra 335: up to 4.6GHz
• Core Ultra 325: up to 4.5GHz

2+0+4 configuration:

• Core Ultra 332: up to 4.4 GHz
• Core Ultra 322: up to 4.4 GHz

As mentioned, some names appear very differently than what has been leaked for Panther Lake previously, and we even have new SKUs.

Responding to comments, @jaykihn0 explains that what was previously leaked was incorrect and preliminary, and that the updated list is the correct one to follow. It also reveals the TDP of the 12- and 16-core components as 25W base and up to 65W or 80W in boost. The other components must have a base TDP of 25W with boost up to 55W.
