AMD's Ryzen 7000 mobile CPUs feature up to 16 cores and 5.4GHz speeds

AMD is bringing out some big guns to take on Intel's powerful HX laptop CPUs, and once again, they're also called "HX." The company's new Ryzen 9 7945HX processor is its most premium mobile offering, with 16 cores and 32 threads, as well as speeds between 2.5GHz and 5.4GHz. It's joined by an array of other Ryzen 7000 CPUs unveiled at CES (AMD also announced low-end chipsin September), which will power everything from budget laptops to extreme gaming and creator machines. The big takeaway this year? There will be a Ryzen laptop chip for practically every need.
