Intel's upcoming Core Ultra 300, the Panther Lake generation of mobile CPUs, has been leaked, providing a glimpse into the core configuration of the chips, their boost clock speeds, thermal design power (TDP), and naming convention. It shows the range maxing out at 16 cores—only four of those are Performance (P) cores—and a maximum boost clock of 5.1GHz. Although the CPU cores don't seem likely to be performance powerhouses, the massively upgraded graphics could make Panther Lake impressive chips for onboard GPU gaming. This information comes from serial leaker jaykihn0 on X. They initially posted a core and clock speed lineup for the entire range, showing that most models feature four Performance cores, with the various designs primarily differentiated by the number of Efficient (E) cores. Every chip in the range features four low-power cores, which helps boost efficiency in low-demand settings. The flagship Core Ultra 300 388H has four Performance cores, eight Efficient cores, and...
