The new many-cored monster will be powered by 2 Nehalem-EX CPUs each with 8 cores of its own. This means that sitting under the hood of the Skulltrail 2 will be a full 16 cores capable of executing a staggering 32 threads simultaneously.
No word on when this monster will be out but I know I will be chomping at the bit waiting.

A humongous 48 MB L3 cache fed by eight channels of micro-buffered DDR3 memory, up to 256 GB of it even on a desktop? Many OS and apps code paths would now nicely fit in that huge cache, but high speed memory would still be useful for streaming and HPC apps. Every Nehalem-EX Beckton processor has a quad-memory controller, e.g. 256-bit interface. With DDR3-1333, you will get 85.3 GB/s. But with DDR3-1600 you would get 102.4GB/s e.g. CPUs would have more than 100GB/s of system bandwidth for the first time in history!
As a bonus, you would still be inside JEDEC specifications, thus OEMs could qualify the parts with no problems. If micro-buffered controllers improve enough to hold up the 1333 and 1600 clock, seeing 100GB/s in Sandra 2009-2010 could be just a matter of time.
