As I understand it, it has been an issue and a major reason for actual cores being as small as they are. The time a signal takes to propagate from one section of the core to another is significant.
- anamax 17y agoChip sizes are a function of yield and performance. Core sizes are designed to optimize performance for a given chip size. (Yes, there's a circular dependence but yield is a huge factor in chip size.) That said, it's been at least a process generation since a given clock signal could be used to synch events on the opposite sides of a core, let alone a (high performance) chip. This is due to both increasing clock frequency and the fact that propagation speed has gone down as feature size decreased.
