What appears to be a nearly full lineup of Intel Core Ultra 300 Panther Lake CPUs has been leaked online ahead of an official announcement.
The new CPUs, which were listed by known hardware leaker jaykhin0, show processors ranging from the high-end Core Ultra X9 388H to the Core Ultra 3 322. When it comes to Cores, Panther Lake features a max of 16 cores, depending on the chip. For clock speed, users are looking at a max boost of 5.1 GHz for the top processor while the more entry-level options reach 4.4 GHz.
It’s unknown if this is the complete family of CPUs for the next mainline release, but it’s enough to get an idea of what enthusiasts should expect. You can check out all of the early specs for yourself below.
Intel is rumored to release Panther Lake to the public in Q1 2026.
