I know i always get confused with CCX's but
IIRC that's not correct, a single die consists of 4 cores and associated controllers/hubs, anything above that uses two (or more) physically separate four core dies.
Although none of that changes the inaccuracy of Intel's claim as a CPU is, as you say, the entire package
IMO.
Intel do seem to be playing very fast and loose with their marketing of late, first it was showing the world they had a 28 core CPU running at 5Ghz on all cores only to get rumbled that they were using a chiller, and now they're trying to lay claim to the first 'mainstream' eight core CPU, one could almost say their trying to mislead investors.
