If really has to do how well the OS and hardware are designed for power management.

A dual-core CULV SB with a stripped-down chipset would be nice.... even better would be if Intel packaged it as a SoC.

Sig rig is a tablet PC with a 6 cell. Gets 5 hours of use out of it.

They can easily make this PC lighter, and furthermore longer lasting. Simply disable 3 cores (if quad) and lower the GPU clock speed dramatically. A single sandybridge core and low clocked intel GPU is far enough for HD playback and simple searching the internet/note taking/programing (internet).

If and only if voltage remains the same between the two states. And if the said program in question uses more than 1 core. If you are opening word, excel, surfing the internet, checking e-mail, and simple things like that, you still draw more power out of the quad than a single core. The constant switching of threads between cores just loads up the power consumption.

You know, i bet you that would be one of those benchmarking "yeah i did it" goals for the tablet market. Someone that can develop a tablet that can detect the real-time typing speed of a person could probably boast that they have a tablet that rivals the touch of a keyboard.

It's much more complicated than just voltage though.... It basically boils down to "Can certain components be powered off, voltage lowered, and/or downclock?".

If you are running a single-thread application, the additional cores power draw should be near zero if OS, app, and hardware are well-designed. Yes, there is slightly more but most people would rather have the additional processing power than not. Really, a dual-core today would be sufficent for 99.99% of people though.

As for the thread mananagement.... that's an OS and hardware design issue. Any memory miss or transfer is very power expensive.

Touchscreen do "detect the real-time typing speed of a person". The issues are haptic feedback and space/layout constrants.

It's natural progression. If the performance of a certain class of products can be vastly increased then why deny it based on the opinion that no one "needs" one that powerful?

In that same sense why overclock your PC?

I noticed on this rig here if I force the CPU state to not exceed 50% I gained about 30 minutes of battery with no to little performance loss (only on start up). Clock speeds and voltages remain the same, but 2 cores (1 with HT) does not get used. Dropping the voltage to compensate for single core with HT will increase that battery even more.

By my understanding, if the programs in question actually use multi-threaded operations then a single core will draw more power then with multi-core enabled like you basically said. But if say you are using word, or firefox, or simple note taking in a powerpoint, having the rig remain at the same voltage and cycle between cores will still draw more power then a lower volt single core state. The other cores do still get used if the program is designed for single core use. 5 seconds of 1V should draw less power then 2 seconds at 1.2V. Especially in idle.

But I agree, there are other methods. I'm just throwing that out there.

At any one time the OS is using hundreds of threads at once. If all are designed for single core use the OS will cycle between cores to throw the threads around. That is what I noticed with the performance tab open anyways.

If I can carry my phone around all day, but then when I need a screen+keyboard to do "netbook type work" I can just plug that phone into a portable laptop-shaped docking station...then what purpose does a netbook serve at all? If Atrix works and takes off, that's the end for netbooks for sure.
Sry Motorola, but "work" and a 4" screen are mutually exclusive to me.

You are correct in your case.... but thread management and power consumption are big targets of ARM (and licensees), Intel, and AMD now. They are refining their processes to do it better.

Intel's Turbo Boost would help in the example you described. If you have a single-thread that taxes the system, the CPU could idle the other 3 cores and overclock/overvolt the single core.

Sandy Bridge is a Tock. Ivy Bridge is a Tick. By the definition of Intel, Sandy Bridge is a microarchitecture change while Ivy Bridge is just a refinement and die shrink. Ivy Bridge will not be a big thing.

It's a 11.6" screen/keyboard docking station...

In the future, I believe smartphones will plug into and drive "good enough" laptops.

Ivy Bridge will be a smaller version of a big thing.

If Sandy Bridge will be good for tablets, I can imagine Ivy will be much better...
