The 6 and 8 core parts will be Socket R (LGA2011) using the X68 chipset if they're anything like the SB Xeon's, but they'll still be Sandy Bridge and not Ivy.
Though one of the issues, though potentially great for performance, will be quad channel memory, bandwidth through the roof no doubt but, doubling the trace routs of memory, and pinout of the chip = mucho expensiveness. Boards will be silly priced, potentially silly cost even compared to current x58 silly prices.
The tech radar "performance" idea's are, dodgey , the 50% faster is stated for essentially server duties. LIkewise Sandybridge in its main performance improvement area is transcoding/encoding, thing is its unlikely to be used for far reaching things.
Current gpu acceleration is much slower for transcoding/encoding, because its not so specific, programable thats what lends it to SO many things. Bulldozer first iteration I don't think has the same kind of specific encoder/decoder function, while gpu will bring it in future iterations, I don't know if they'll dedicate die space to a specific transcode engine. When you do hardware for specific acceleration it will be insanely fast, but highly limited, and you can't put in a new part of a core to accelerate EVERY single function.
Though as transistors get smaller we'll probably see more specific hardware acceleration for certain things from both camps.
That report makes it sound a little like Bulldozer's design allows 2 cores in a smaller space and to be almost as fast. But we're not talking that a module with 2 cores in, will be as 80% as fast as 2 phenom 2 cores.
The real magic from Bulldozer comes from the fact that the second interger core, which add's 80% performance of another single core, adds only 5% die space.
Intel has 6 and 8 cores coming the end of the year, but AMD has 16 core Bulldozer's coming next year, WELL before Intel has 16 core chips to compete with it.
Bulldozer and Ivy bridge are both going to offer silly performance, but Bulldozer should pretty much stomp all over Intel, with double the core numbers, in the midrange to lower high end space. Up to £300-350 maybe AMD should be insanely fast. 8core Bulldozers vs 4 core Sandy's, for about the same price, with cheaper mobo's.
I'm not sure when Bulldozer is getting a die on board, its not entirely clear right now but should bring insanely good chips. I wouldn't be surprised to see quad core Bulldozer(2 module) + gpu to replace Llano fairly quickly(in cpu terms, that means 2012). Might have to wait till 22nm for 8-16 core bulldozers with a gpu on die.
Oh wait I used red too.
