people keep asking if the turbo boost will only boost two cores while @ 5ghz, and the answer is no. turbo boost has two settings, the first boost (up from stock clocks) boost all 8 cores, the second boost (which in this case is 5 ghz) will boost 4 cores. from my understanding this is how it has always worked and there is no reason to believe it will change with this new chip.
personally, i can't wait for this chip.
there are a lot of unknowns as the chip has not been released yet, so we'll just have to wait for benches and cpuz validations.
hwmonitor will tell the true story.
as an example: you have a thermastact in your cars radiator, it's rated at 220 degrees f, it does not mean that you engine temp runs at that temp,,it means that you can go up to that temp when pushing it really hard. if it ran at that temp continually, you would be blowing antifreeze continually, which you don't,,, because it almost never reaches that temp of 220 degrees.
yeas, i believe this chip will use more power, but i can't see it using any more than when you overclock to 5 ghz anyway, and since we'er talking about base clocks and stock voltages, it will probably be a little less power consumed than an overclocked rig @ 5 ghz.
congrats AMD, on breaking through the 5 ghz barrier, inovation at work .
