The power depends on many factors......and those same factors decide frequency. How can that freq news be worthy without any mention of power ???

Hmm... "under typical operating conditions" are the key words here, so this is really an over-clocking test, with no margins included - just bragging right stuff, not real engineering.

Finally, there is real speed in ARM land! I can't wait to see these on the market and on Small Board Computers for use in robotics. If nothing else they would be nice to have for those cpu sucking applications like: FP or Vision.

Any paper that supports your case. I know that at 28nm your static power become a huge issue. The dynamic power is a function of the high freq. That is what you pay for the high speed. Unless you can explain that it is not related to freq but process, I think this product could go into mobile devices.

Does that really matter? How can you calculate the power? I think it is the freq that is news worthy. The power depends on many factors...

At 3.1Ghz this consumes more power and is use full with a system connected to power or for a short time usage with batteries. So much also the heat dissipated in this chip.The cooling system got to be efficient and i feel this is more suitable to desk top items rather than handheld appliances at 3.1Ghz.

This is great news. So when can we expect 20nm products from TSMC? Is TSMC close to tapeout products in 20nm process ?
