Where did I call it co-incidence? I fully agree Intel are copying AMD, but AMD are copying Intel in more ways And no, I don't mean any software at all, I'm talking purely hardware/architectural.
I think the Hexus article is misleading if it's trying to suggest it's hard to distinguish between nehalem and AMD's offerings - the core architecture is completely different, despite AMD taking on many of Intels ideas on the inside and Intel taking on two of AMDs on the outside.
PS I like AMD too - I run one after all.
