Yes, there are such CPUs i3-2100T, i5-2500S, i5-2500T, i5-2390T
I have put together a test system including i5-2500K and measured the PC power usage at the wall power socket.
Power SS-400ET Processor i5-2500K Board DH61WW Memory 4GB DDR3 1333Mhz Storage 500GB WDC 6Gbps PC Power CPU Package Power IDLE 23 W 5 W Archiving 7ZIP Bench 80 W 45 W 13500MIPS Rendering CB11.5 Bench 32b 90 W 55 W 4.9 pts BluRay 1080p 35 W 15 W
Seasonic SS-400ET Test Results DC Output (W) 21.2 41.6 60.2 81.9 104.7 124.1 145.2 AC Input (W) 32 58 78 102 128 150 175 Efficiency 66.30% 71.70% 77.10% 80.30% 81.80% 82.80% 83.00%
Basically 23 Watts Idle that is AC Input and the DC output remains between 50-80% depending the load.
The difference between AC and DC is lost in the PSU as heat.
i5-2500K is almost 3 times more power hungry than i5-2390T.
I hope this answers your question.
Yes Nipe that good Showing all that. 23 Watts is still a lot just sitting there. But it is good if it will go up and down even more how you use it.
Looks like still have to wait for one. A 2 core CPU were one core is like a low power Atom CPU and the other one like a i5 or more.
I am using a TonidoPlug 2 now as a server. It's a little slow but does the job. It saves a lot of power. Has a ARM CPU in it.
I guess if they could make a PC like a Cell phone and then when it needs it switch to a high power CPU that would be the best for a home PC.
But Cell phone have ARM CPU's the less trasitors you have the less power it takes. I guess Intel wishes they did ARM long ago now it my be to late. ARM uses program code to be like a none ARM CPU. Computer code don't take more power.
ARM is a totally different architecture than X86. Only 3 companies in the world have X86 certification that I know of Intel, AMD and VIA. It must be much easier to get an ARM license and the initial startup costs are much less than X86. Can you imagine a company like Qualcomm (who leases ARM architecture) to try and startup an X86 line? Intel and AMD would completely obliterate their product. This is very similar to why Intel decided to drop their dedicated video card (Knights Cross?). AMD and nVidia would've just come out with something that was already leaps and bounds better. Basically Intel would be releasing new cards just to try to keep up with 2 generations old performance from AMD and nVidia.

If you mean Knights Corner, where did you see that they'd dropped plans for it? All I've found is that it'll likely be released later this year or early next year. Clearly it's contentious as to what benefits it'll offer over competitors hardware but that's expected in such a market.
