What is Ryzen 5000 mobile? Ryzen 5000 mobile differs from AMD's desktop chipsets because it's a purpose-designed monolithic die comprising the latest Zen 3 cores, slightly improved graphics, a better memory controller, and power-focused improvements. The Ryzen 5000 line of CPUs is built on TSMC’s 7nm process. The CPU isn’t exactly new, for the simple reason that the company designed Ryzen 5000 CPUs to be pin-compatible with the previous Ryzen 4000 motherboards used in laptops. That requirement does limit how crazy AMD could get with the new chip. Still, the new Zen 3 cores do not disappoint one bit. AMD One of the major changes between the Zen 2 cores in Ryzen 4000 and the Zen 3 cores in Ryzen 5000 was the base level of cores in a Core Chiplet Die (CCD), which increased from four to eight cores. Like the desktop version, that meant all eight cores would have access to the same L3 cache. With Ryzen 4000, four cores shared 4MB of cache with another four cores that had their own separate cache, a more awkward arrangement that slowed performance.
