Because the RTX Cards have no ASIC.
That ended a long time ago.

Now that asic is the thing of the past is there a new way to tell if a card is good or great?

Lower quality chips will have a higher default voltage. Higher quality chips will have a lower default voltage. =)

All my chips that have had a lower default voltage will overclock better on air, so yes it does tell which card is the better overclocker. =)

^ exactly. =)

ive had blast toying with kingpin all week, I've got it dialed in pretty solid, I have 115 on the core which results in 2165 but after load in goes to 2130 and ive played shadow of the tomb raider for hours last night, only one time went down to 2115 it was briefly I canceled background process and the entire time it stayed rock solid 2130 did not fluctuate not even by one mhz, Im wondering if I put a hydro on it and get it cooler if it will clock itself higher, but it stayed at 46c couple times it creeped up to 50 51c but all benches passed fire, time, heaven, valley, superposition,
as well as game benches lie gears 4 and both tomb raiders
