  Anandtech - AMD chiplet skálázási korlátok.
  Does an AMD Chiplet Have a Core Count Limit?

  "So is AMD's Zen 3 8-Core CCX Really A Ring?
  AMD tells us that its eight-core CCX structure is a bidirectional ring. If that’s the case, then AMD is going to struggle to move beyond eight cores per CCX. It could easily double cores per chiplet by simply doubling the number of CCXes, however beyond that the ring needs to change.
  In our testing, our results show that while AMD’s core complex is not an all-to-all connection, it also doesn’t match what we would expect from ring latencies. Simply put, it’s got to be more than a ring. AMD has been very coy on the exact details of their CCX interconnect – by providing a slide saying it’s a ring reinforces the fact that it’s not an all-to-all interconnect, but we’re pretty sure it’s some form of a bisected ring, a detail that AMD has decided to leave out of the presentation.
