The PN64 can be equipped with Alder Lake-P processors up to an i7-1280P or Alder Lake-H ones up to an i7-12700H coupled with DDR5-4800 RAM. No Ryzen 6000 processors for the AMD models this year, but the Ryzen 5000H APUs should still make for a decent upgrade over last year's Lucienne Ryzen 5000U options.
