We have to wait until Q3'13 before replacing the Sandy Bridge-E CPUs? Nooooo ...
A recently leaked slide reveals one of Intel’s upcoming Xeon-branded server chips coming in Q3 2013. The Xeon E5-2600 V2 is an Ivy Bridge-EP processor and will be compatible with motherboards featuring the LGA 2011 socket.
The Xeon E5-2600 V2 in particular has a 70W TDP (thermal design power) rating while the highest-end Ivy Bridge-EP CPUs will have TDPs of up to 130W. The E5-2600 V2 has 10 physical cores, and with HyperThreading it can handle a maximum of 20 threads. Each physical core has access to 256KB L2 cache and the chip has a total of 30MB L3 cache. Further, this (and other) Ivy Bridge-EP processor will support up to 1866MHz DDR3 system RAM.
Interestingly, the Xeon E5-2600 V2 is merely the middle of the road part for Intel. The company will be releasing processors that are even higher-end than this one. They will have up to 12 physical cores which means up to 24 threads. And paired with Intel's 22nm manufacturing process and 3D transistors, these chips will fit right into workstations and server rooms.
