AMD's Bobcat and Bulldozer

[-Boris-]

There's a Bobcat die floor plan on the slides, anyone care about estimating the die size? There's 512 kB of L2 cache consuming 31% of the total chip area. If Bobcat was made on 45nm process and the cache was the same as L2 in Deneb/Thuban cores, it would make Bobcat core be around 13 mm² (core with L2 cache only - gpu engine and memory controller not included).

Were is that floor plan?

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.

The AM2 part is probably a typo, or they are counting Phenom II as "AM2 and AM3".

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

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

What I wonder is how that could save that much die space that they feel it's a good move.

Same clockspeed + deeper pipeline.

Clockspeed is something Anandtech was guessing. We know nothing about that. And we don't know how much deeper the pipeline is.
