AMD's Bobcat and Bulldozer

[Opteron146]

No, AM3 cpus work in AM3+, besides, the number at the end suggest what typ od memory it uses. Bulldozer must be some kind of AM3, not AM4. And since two sites claims that Bulldozer won't work in AM3 boards I think that there is something to it.

I found the 2nd source now. That one is bogus, too. Lostcircuit wrote:

Backwards Compatibility

All Bobcat and Bulldozer enabled motherboards based on the AM3+ socket will be backwards compatible with earlier AMD AM3 CPUs but AM3 CPUs will not be a drop-in replacement for existing processors in existing motherboards.

They wrote AM3 .. not AM3+
So literally, they mean that I cannot use my X4 965 in old AM2 boards.
Surely, that is probably not what they meant, but that is what they wrote.

All in all we now have two sites which both seem to have hurried to get their articles online in time and therefore didnt check them thoroughly. Hence I dont take any of them for granted and I will wait for an updated / clarified version.
I agree on Olivon's view, I also dont get what Lostcircuit is saying. Maybe they want to say that AM3+ CPU are incompatible to existing boards ... but maybe they just misunderstood it, too.
