This is something I am wondering. For something like the 5800X is it 1 CCX or 2-4 core? Is the 5900 2-6C or 1-8+1-4 . The performance implications could be high.Their 640 single thread score on CB20 was pretty impressive. I think I'll probably get a 5950X... but we'll see how things fare. I want a top binned chip this time around though. My 3900X is a really poor sample it seems, and with the move to 8-core chiplets, that means the "bad" dies are being used in the 5600/5900?
