Introducing Precision Boost 2 and Mobile XFR
AMD's SenseMI technology is back and with a vengeance. Power consumption requires great optimization on the mobile side of things, as while a few more watts in a desktop doesn't matter, it matters a great deal for mobile implementations. AMD has gone and leveraged SenseMI's sensor network to its fullest.
Precision Boost 2 is part of SenseMI and utilizes a brand new opportunistic algorithm for a much more dynamic core boost. It offers a much more tuned boosting mechanism, which favors the boosting of one, some, more, and all cores. It offers greater performance depending on how many cores are utilized, as you can see in the chart on the right.
Mobile XFR (mXFR) is much like normal XFR in regards to going above and beyond Precision Boost levels. However, it utilizes Precision Boost 2's temperature sensing to get every last drop of performance out of the processor. Just like on the desktop, if you can run the CPU cooler, it will automatically run faster.
I also wanted to take a chance and mention that Max z-height is now 24% thinner, which makes it great for ultra-thin notebooks.
