AMD's Bobcat and Bulldozer

[ajaidev]

Forget that comment, they just proofed that they dont have any clue.

AM2 CPUs cannot work in AM3, however they should now be able to work in AM3+ ???

Sorry but:



They definitely understood something very, very wrong.

lol did not notice that was more concerned over the Bulldozer not working with non- AM3+ parts.

Agree that's not good for a AM3 actual board.

But C32 and G34 will be working.

i don't understand fully this part in anandtech review :



Why a 2 Alu core could be faster than a 3 ?

WTF if there is not 4 alu and 3 agu per core, where is integer performance ?

I'm afraid about this too :



Same clockspeed + deeper pipeline.

AMD says that 3rd ALU was not much used in PhII and it was left so as not to redesign that part. But yes there will be a performance dip due to this in single threaded ALU dependent app's. Lets hope the other enhancements actually work to cover up this missing ALU.

Branch Prediction is said to be aggressive and it has to be with as deep a pipeline bulldozer has otherwise we can have a call problem. On the bright side deeper pipes may enable better overclocking well that depends a lot on the architecture.
