With the Zen 3 based Ryzen 5000 and Milan processors, AMD aims to discard the concept of two CCXs in a CCD. They just have a differing number of cores disabled per CCX. All Ryzen parts, even quad-core parts, ship with at least one CCD. A CCD consists of two CCXs paired together using the Infinity Fabric Interconnect. However, while CCXs are the basic unit of silicon dabbed, at an architectural level, a CCD or Core Chiplet Die is your lowest level of abstraction. For example, the Ryzen 5 5600X features two CCXs/CCDs, each of which has one core disabled, for a total of 6 functional cores. However, this is offset by the fact that Team Red salvages partially functional CCXs with, say, two or three functional cores, to create different SKUs. A negative is that the baseline cost of manufacturing can be somewhat on the high end since AMD needs to pay up for a minimum of four cores. There are pros and cons to having the CCX be Ryzen’s basic functional unit. The basic unit of a Ryzen processor is a CCX or Core Complex, a quad-core/octa-core CPU model with a shared 元 cache. In newer Ryzen 30 parts, the amount of 元 is higher and it’s referred to as “Gamecache.” The basic unit of a Ryzen processor is a CCX or Core Complex, a quad-core/octa-core CPU chiplet with a shared 元 cache. These two functional units lie at the heart of AMD’s modular approach to Ryzen. This means that, at any given price point, AMD can deliver more cores, more threads, and therefore, better multi-threaded performance, than Intel can, even after a number of price cuts. The Ryzen 9 5950X features 16 cores while the Threadripper flagship, the 3990X boasts an insane core count of 64, the same as the Epyc Rome parts. It allowed AMD to increase the core counts to never-before-seen figures in the consumer market and set the groundwork for a revolution of sorts. But, the chiplet or MCM design (Multi-chip Module) is at the heart of it. There are many factors responsible for AMD’s recent success in the consumer market. But what is a CCX and how is it different from a CCD in an AMD processor? Let’s have a look. AMD’s Ryzen CPUs are made up of core complexes called CCDs and/or CCXs.
