The video explores the contrasting CPU architectures of AMD and Intel. AMD's approach involves core complexes (CCX) within chiplets called CCDs, connected by the Infinity Fabric interconnect, offering cost savings and scalability. In comparison, Intel traditionally utilizes monolithic chip designs but is transitioning towards chiplets, known as tiles. Intel's mainstream processors, Meteor Lake, feature tiles connected by EMIBs, offering a cost-effective and scalable solution. Both companies are evolving towards modular chip designs, yet monolithic designs are expected to remain in simpler systems. This shift towards chiplet connectivity brings benefits but also incurs costs, with traditional designs still prevalent in budget-friendly devices.

In this part of the video, the speaker discusses the differences in CPU architecture between AMD and Intel. AMD Ryzen CPUs consist of core complexes (CCX) with newer Zen3 chips having 8 cores per CCX. These CCXs are grouped on chiplets called CCDs, with up to 2 CCDs per processor for a total of 16 cores. The Infinity Fabric interconnect links the CCXs and CCDs. This approach offers cost savings, scalability, and efficient design. On the other hand, Intel uses monolithic chip designs, leading to direct core communication but lower yield and scalability. Intel is also moving towards chiplets, referred to as tiles, to stay competitive with AMD in the future.

In this segment of the video, the speaker discusses Intel’s lineup of mainstream processors named Meteor Lake, which are based on tiles connected by EMIBs (Embedded Multi-die Interconnect Bridge). EMIBs are described as a more cost-effective and scalable solution compared to AMD’s Infinity Fabric for connecting chiplets. Intel also mentions another method called Foveros for stackable chiplets, although it has seen limited adoption in consumer devices. While both Intel and AMD are moving towards more modular chip designs, monolithic chip designs are expected to persist in the lower-end market for simpler systems. The speaker emphasizes that these advanced methods of connecting chiplets come at a cost, and traditional monolithic designs will still be prevalent for budget-friendly devices.
