To overclock today we are using the latest version of Sapphire's TriXX tool – V4.6.2.
The Sapphire HD7790 2GB OC model showed a very healthy core clock increase, from 1050mhz to 1,253mhz. This translates into almost a 20% increase which is remarkable.
It does raise a point I made earlier in the review however – why is the 2GB OC model of this card clocked at 1,050mhz and not the same 1,075mhz speed of the 1GB OC card? It makes little sense to me.
The massive 20% core overclock increases the final score from 3,670 points to 4,078 points, around 150 points behind the HD7850.
