And that's without mentioning the large amount of hidden state carried by a CPU purely for performance reasons: physical-to-memory address translations are done via tables stored in memory, but this data needs to be cached in a translation lookaside buffer inside the core. Cache lines can be shared by different cores and must track their state, are they owned by a core? Shared? Is the data dirty locally and needs to be fetched remotely? 8/31
