AMD Scorpius desktop platfrom and 32 nm Zambezi in 2011

APU, as in "accelerated processing unit". GPU-on-CPU. Few Bulldozer cores with a low end GPU on-die.

Now that gets strange. How does the CPU utilize the APU? If there's a sequence of certain instructions, they are executed by APU, just like floating point operations are executed by FPU? If so, great. Now we just need compiler support.

this will likely end up similarly to how x86 CPUs handled x87 co processors.

The AM3r2 must be related to AM3, otherwise they'd get a different name. Should have been AM4 IMO, less confusion.

Either way, it doesn't sound like Bulldozer to me. I thought it would need a completely new socket?

Someone over at AMDZone has speculated that it is AM3+, i.e. Zambezi would work in existing AM3 sockets and in AM3+ sockets, but there would be perhaps be a minor loss of performance in regular AM3. Regular AM3 processors would not work in AM3+, ie downward compatibility but not upward compatible. Of course Zambezi would not work in AM2+ either.

The AM3 socket has 940 pins, but I think the AM3 cpus only use 939 pins. Maybe the extra pin is reserved for something. There are some really good threads on AMDZone about the technical justifications for and against this compatibility.

AM2+ was also named AM2r2 internallt so my guess is that it's AM3.

Zambezi will be based on the Bulldozer architecture, and most likely only support DDR3, so it will be socket compatible with AM3 and AM3+. Wonder when AMD will finally change socket?
