Following on from the Sandy Bridge processors, this year will see an influx of new CPU'€™s with a common many core strategy, leading to more economic performances per Watt systems:
As well as Bulldozer AMD is set to release 6 core (40W; 6.67W per core), 8, 12 and 16 core Opteron CPUs. They have also cut the prices of their Phenom II processors, including the 6 Core desktop processors.
ARM has a new Cortex a15 and plans afoot to increase performance to 100X their present processors within 3 years.
As well as further SB based CPUs for laptops, desktops and servers, Intel has a server processor called the Knights Ferry, a 500 gigaflops processor system. It comprises 32 Quad thread Xeon CPU cores @1.2GHz in the CPU socket, looks like a GPU and uses GDDR5. This prototype has 80 threads Intel is planning a 50+ core commercial version (Kings Corner) based on 22nm technology.
Microsoft are asking for 16core Atom processors for servers, but start-up SeaMicro already has a 512 processor atom server.

Just highlighting the increasing efficiencies and competition across the full spectrum of processors, from 1W palmtops right through to exotic cloud designs. Not saying anyone should buy a cloud server :p

I think we are more likely to see a few of these in due course,

Intel and IBM demonstrate 128-thread Nehalem-EX server

32 core/64 thread XEON 7500

Just bought two Xenon 3.33 ghz six core processors. I am probably already obsolete! 3K for obsolete processors , go figure. Fell like I am one of the customers in the movie " Man who fell to earth"! Am building this machine as tired of being run over everyday, use to be 10k points/day was really good. Now it takes twenty plus to do that. We will see how long it takes once new machine up before I start bearing tire tracks on my forehead!!!
