Intel Devising Sub-10W Nehalem Derivatives

[btarunr]

Intel pushed its performance supremacy lead further up with the introduction of the Nehalem micro-architecture. The introduction served as a milestone event in the company's history, where it sought to rearrange various components of the PC, by moving certain parts of the chipset to the processor package. In the months to come, with the introduction of the Ibex-Peak platform, the company hopes to migrate even more components from the system core-logic to the CPU package. A lot of engineering potential is unlocked due to the modularity of the various components of a Nehalem-derived CPU.

At the upcoming International Solid-State Circuits Conference (ISSCC) event, Intel plans a decent set of technology demonstrations and papers. The advance program information document shed some light on Intel's itinerary. In session 3 held on February 9, Intel will present papers on its 8-core Xeon processor, following which is a session on 45nm IA processors. The session is on processors built with features characteristic of the Nehalem micro-architecture, in having integrated memory controllers, a coherent point-to-point interconnect, and up to 8 processing cores. Interestingly, the description included a note on the power consumptions, ranging from "sub-10W to 130W", which leads us to believe Intel to have plans on making derivatives of the Nehalem micro-architecture with some very low energy footprints. Another interpretation would be that a new breed of processors could have idle power consumptions as low as <10W. Currently the most energy-efficient Nehalem-based processor known to be in the works is the Xeon L5520 that has identical features to those of the Core i7 series while having a clock speed of 2.23 GHz and a rated TDP of a mere 60W.

perhaps a nehalem based atom? like single core w/ HT? or dual core w/ HT

maybe atom2 or maybe they will make it look cool and put Atom²

out of curiosity, how many watts does a mobile cpu in a phone like the iphone or htc touch pro use?

"sub-10W" it is CPU power consumption when idle. 100-110W when stressed and you got 60W TDP Intel CPU.

Sub 10w for the upcomming 8core ? Niiiice!

Probably something less than 1 watt while under load.
Sub 10 watts will probably be just for normal notebooks, because the Atom has a 2.4 watt TDP and + the chipset brings the total to ~11 watts, so unless Intel makes a 1 watt chipset then it wont compete with the Atom.

You're full of it. Where is your proof? My i7 is rated 130W TDP and under load on stock it's 130W TDP. Go out and get one yourself if you doubt it.

Nobody said that at all. You're reading too far into the article.

Intel has CPU TDP rating similar to new AMD average CPU Power (ACP) rating. Both do not represent actual consumption on 100% CPU load scenario. The most accurate measurement to date is "Standard Performance Evaluation Corporation" SPECpower server benchmark. Look at the database on the official web page .

It might include a northbridge and a gpu too if its a 'Nehalem derivative'.

Your right, noone said that. I simply asked the question. Let me quote myself, i like doing that . . .
' Sub 10w for the upcomming 8core ? Niiiice! '
I have reason to believe i read the article to the point where it finished off with . . . . 'rated TDP of a mere 60W.'

Granted i have a bit of an imagination, but 8cores being just around the corner, i wouldnt consider the question too far fetched. So for clarification it was just a question and not a statement.
