Intel will debut a 10-core Xeon E5-2600 V2 Ivy Bridge-EP Processor as a leaked slide reveals, that's next to 12-core processors BTW. The processor would be released in the third quarter of next year (July-September, 2013). By itself not groundbreaking news, however the specs we can derive from it are interesting none the less. Intel will make them on a 22nm Tri-gate fabrication process (Sandy Bridge-EP is on 32nm), this would save more power from the chip while keeping power consumption at a minimum.

The Ivy Bridge-EP CPUs would sport a whopping 30MB of Cache, DDR3 memory with speeds of 1866 MHz and the high-end 12 Core 4S CPUs would feature TDP of 115-130W  

The DDR3-1866 memory support indicates no DDR4, along with up to 30 MB of cache memory. The chips will be compatible with C600 chipset-based server mainboards which are based on LGA 2011 sockets, these will be released alongside the Ivy Bridge-E desktop platform. Thanks to Computerbase for the slides.
