So how does PVS BIN affects performance ?
a cpu with pvs bin 4 is a lot better than a CPU with PVS Bin 1 ?

.... I have 4 and no... can't OC, UC, UV... basically anything besides stock values the "lot better" cpu rejects...

Might be also the custom kernels fault ... who knows

Till now the pvs bin has zero info value...

[For reference] http://forum.xda-developers.com/show....php?t=2215710

There seems to be a bit of confusion, about the significance of the PVS value. They relate to Process Corners, and in part to threshold voltage, there is a lot more to it than that, but I'll keep it simple.

So far we've seen PVS values of between 0 to 6.

0 seems to indicate a SLOW corner, this means that its leakage current is lower than a 6, but its timings are slower. In theory, this chip should be good for power consumption, but offer less overclocking potential.

So, 6 means a FAST corner, this means that its leakage current is higher than a 0, but its timings are faster. Again, theoretically this chip offers good overclocking potential, at the expense of possibly higher power consumption.

Firstly, don't worry about it, all these chips have to pass Qualcomm's quality assurance, and lastly a higher PVS number is not necessarily the best, it depends on your priorities.

Its just binning based on samples from those batches, you could still end up with an OC dud despite having higher PVS as they only sample a few and cant test every single one. But as the guy before me said they all meet quality assurance standards.

Lower voltage can mean lower heat, but there are other factors also at play.
