Having already leveraged the smaller, optimised Zen 4c cores in its EYPC server CPUs, AMD is bringing its latest technology to the world of budget laptops with two new Ryzen APUs, sporting up to four Zen 4c cores next to two Zen 4 cores. The compact cores aren't AMD's version of Intel's Efficient-cores introduced in its hybrid Alder Lake architecture, though, and AMD is certain you won't notice any difference between them.
Up until recently, no matter what AMD CPU or APU you used, the processing cores inside them were exactly the same. From the hulking 64-core EPYC 7742 down to the tiny four core Ryzen 3 7440U, each one used the same chips to handle all of the number crunching. That all changed when AMD introduced Zen 4c, an optimised version of the Zen 4 design that shrunk the amount of die space required by 34%.
