Specs on some GPUs list “Processor Clock Tester (MHz)” where “Processor Clock (MHz)” is usually listed. For example, for GT 630 (Kepler) we have
Graphics Clock (MHz): 902
Processor Clock Tester (MHz): 1804
What does this “Tester” suffix mean? Is it any different than simply “Processor Clock”?
Also, shouldn’t Processor Clock for GT 630 Kepler be same as Graphics Clock - as always on Kepler?
