Overclocking
We're mixing things up with RTX overclocking. Rather than the play the GPU lottery and push samples to their absolute limit, we're keeping things consistent between cards by using Precision X1's built-in Scanner Tool to help determine an optimal frequency curve.
There's not a whole heap of headroom on the core - EVGA is already at the limit of what partner cards are willing to do - but extra oomph on the memory always helps.
Worth it? Probably, and noise only goes up by a decibel.
