Intel is prepairing to launch their fastest and higly expected 8-core Neahalem -Ex  processor .Well you are thinking that what to do with 8-core processor and yes you are right this intel processor is server kind and is a great news for server owners  and it will launch within this march  and it will be the fastest processor till the date as told by Intel’s Xeon Platform director , Shannon Poulin.
This processor will be targeted at four -socket servers the each physical core can be able to rin two thread st a time, powering the chip 64 virtual processing cores on the servers.
This processor is made from 45 -nm process ,with memory controller to improve system speed by cutting its data bottlenecks as earlier  intel’s processor apart from this chip will also powered with seperate buffered memory chips to store data temporarily alongside the main memory for faster execution of tasks.
A look on Nehalem-EX 8-core chips.
