Does anyone have any experience with Turbo in a tablet CPU, or has anyone read any articles examining the subject? Does the feature make any difference to the tablet in real world usage? (I'm talking about typical bursty usage when browsing the net etc, not sustained benchmark workloads where obviously there is no TDP headroom for a frequency boost.)
I'm weighing up whether it is worth getting the i5 version of a Windows 8.1 tablet instead of the i3 version. The price difference is £100, which is quite a lot, but I don't want to fork out for a tablet which turns out to be too slow and needs replacing.
The two processors in question are the i3 4020Y and the i5-4300Y. They have a tiny 100MHz clock speed difference in the base clock, but the i3 does not have turbo boost enabled- whereas the i5 can boost up to 2.3GHz, an almost 50% clock speed increase!
But will I ever actually see the effect of this in the real world? Does a fanless tablet have enough thermal headroom to let it hit 2.3GHz, or will it never get anywhere close to that? And even if it does, is the difference in performance enough to make a noticeable difference?
