Ex AMD designer: Bulldozer to disappoint

[demonkevy666]

And you milk out ~80% more operating efficiency?

no you miss understand.
I'm not milking anything out it's common scaling from one to two.
just like in gpu's.

example
1 cards 100% vs 1 card
2 cards 190% vs 1 card you'd like 200%
3 cards 260% vs 1 card you'd like 300%
4 cards 320% vs 1 card you'd like 400%

since it can't be perfect you get that first number instead.

(that's not bad scaling when compared to one card for crossfire)
scaling on cpu's can be over came by clock speed look at cinebench 11.5 for examples.
