Dunnington, or should we start calling it the six -core Xeon X7460, will aim at the large server market and this very innovative CPU will fit into the Caneland platform. You should see it as Tigerton’s big brother that will score some untouchable performance numbers.

If you put four of these CPUs together, and this should be possible, you will end up with a stunning 24-cores, and AMD needs to plug in six CPUs to match Intel’s four. Six CPUs naturally draw more power and you usually plug in either four or eight CPUs; and eight CPU platforms are rather rare as they are expensive.

As we already said yesterday, the fastest six-core CPU will work at 2.66GHz, has 16MB of cache and works on a 1,066MHz bus. We heavily suspect that it works in Socket 604, something that Intel currently uses for its Caneland platform. The Xeon X7460 will cost a stunning US$2,651 at launch. This currently looks like the most expensive Xeon of all times.

The second in line is the Xeon E7450, and this CPU works at 2.4GHz and has 12MB cache memory. It also uses the 1,066MHz bus and the same Socket 604. It will cost $2,235 at launch.

They are not really the cheapest things around, but just keep in mind that the fastest quad-core based-X7350 with 2.93GHz clock, 8MB of cache memory and the same 1,066MHz FSB in FC-PGA6 socket sells for the same $2,235.
