Power, Temperature and Noise
Given that performance is in line with a reference board, it is no surprise to find that power consumption is practically identical too.
Here's an area in which Palit does manage to get ahead of Nvidia's reference design. When gaming, core temp is reduced by up to seven percent.
Noise levels are improved too, albeit by less than five percent. Decent-enough numbers all round, but no major justification to choose the custom card over a reference board.
