Better known as Intel's microserver with the "Centerton" brand, Atom S processors appear to be available initially in three dual-core versions. The CPUs will integrate a dual-die structure with two 32 nm Saltwell cores with HyperThreading capability and clock speeds of 1.6 and 2.0 GHz.
The 1.6 GHz version will be offered as S1220 and S1240 versions, whereas the S1240 consumes 6.1 watts and the S1200 is rated at 8.1 watts. The 2 GHz model checks in at 8.5 watts. For Atom processors, these are rather generous power budgets, which are likely due to greater feature integration such as an integrated memory controller. CPU World note that, while the Centerton Atoms will need external discrete controllers, "they will not require Platform and I/O controller hub chips".
Centerton will be Intel's first move into the micro server market, which appear to have special appeal in cloud scenarios and run applications that do not need the massive performance of a Xeon processor and virtualization makes little sense. Centerton servers with up to two processors per server unit could be used especially in data analytics, storage and networking applications.

This could be really cool with Haswell cores supporting TSX.Reply

Grass PeerHow? What do you mean?Reply
Sorry, I meant the whole many low-power core server idea. TSX makes that significantly more efficient by reducing locking overhead.
These Centerton's are made to push ARM out of the server market. ARM has slow memory interfaces and doesn't address large amounts of memory (32-bit processors). With software compatibility at stake, Intel probably staves off ARM on the server side... for now. The game will change in 2014 when ARM gets 64-bit cores though and Windows ports a full server side OS to ARM. Of course, by then, Intel might have Silvermont cores at 14nm (out of order instruction, better feature integration, better FPU, etc.).Reply
Is hyperthreading useful for servers? I'm pretty ignorant when it comes to server things.Reply
teh_chemIs hyperthreading useful for servers? I'm pretty ignorant when it comes to server things.Reply
It can be extremely useful. Just remember a server is a glorified PC that is meant to do a certain task very well. It can even do multiple tasks well, but it really depends on what you're using that server for to determine whether or not it'll offer significant boosts with HT or not.
Centertron atom? What a horrible name, its like a Celeron and an Atom had a baby, and the baby was put into a laptop with Centrino wireless.Reply
While I appreciate the small thermal envelope, will these allow a higher density and higher performance per watt than a low power Xeon? Unless these can perform at 60% of the performance of the LC3518 Xeon, or until you can pack 8-16 of these into a blade then I don't see the point in a server environment.
Why are these commercial companies always making such a mess of this?Reply
Wouldn't it be easier to say... downclock an existing Ivy Bridge to much lower performance?
Say... 1GhZ per core, and do the same to the IGP and automatically lower the TDP to really low levels?
Maybe they can even throw out some of the 'features' that no one really uses and limit cache.
Anything to get the power envelope down to under 10W and use that in smartphones?
Tablets can get away with the same, or a bit larger power envelope.
Of course... none of that would even approach electronics made from a combination of synthetic diamonds and graphene (which would in smartphone form probably come close to the power a supercomputer at currently low power envelope).
Sigh... usage of silicon (inferior material).
while you can downclock an ivy bridge chip to save power, you eill nrver get it down to those levels, it has too many transisters and even at a very low clock speed, there is a minimum voltage tha the CPU can handle before becoming unstable. It just isn't designed for really low power usage.
