I will be upgrading my win7 32 bit to win 8.1 64 bit and i was wondering how much i will see improvements in terms of speed.
Like suppose i get 10-12 fps in xenoblade chronicles in dolphin 4.0.2, will i get 20fps if i use the latest development build as a lot of optimizations have been done since the last stable version

The difference was somewhere around 20-30% last time I remember one of the devs measuring it. Dolphin itself has gotten insanely fast in comparison to 4.0.2. It'll easily add another 30+% by upgrading from 4.0.2 to the latest revision (it should, unless something is fubar).

You'll notice some improvements, but don't expect miracles, your CPU is veeeery old...

haha.. i know that. I thought of upgrading but after hearing about skylake and intel's claim that it will one of the most significant upgrade, i decided to wait few months.
And okay i will report the improvements after upgrading, hoping for the best.

AVX-512 and SHX instruction set support FTW.

AVX-512 is important for getting decent performance with (pixel-accurate) software renderers.
SHX enables the use of better checksumming/hash algorithms. Useful for texture hashing with very low overhead.
