Thuban/Deneb was max 3 with the average being more like 2.5....
That's not what i got from the article I linked to...

Thus to improve throughput (by decreasing core size), AMD reduced the number of integer execution units.
Do you think the article is wrong? it is quite old.

P.S. I think Intel can get away with having too many EU's because of hyper threading.
