The card remains based on Kepler Technology by using the GK106 core and utilising a 28nm manufacuring process. Perhaps the most notable difference between the specifications above and that of the original GTX650Ti is that the memory interface has seen an improvement from a 128bit to a 192bit interface (3x64bit controllers). The card is also clocked to 980MHz however users will see a typical BOOST speed of 1033MHz. NVIDIA claim most users will be able to overclock the card past 1100MHz (card dependent) which seems feasable.
It is also worthy of note that the BOOST version of the GTX650Ti we have for review today also features SLI, a key features that was missing from the vanilla GTX650Ti.
Power consumption is however slightly increased slightly to around the 115W in normal operating conditions with this figure increasing depending on the load conditions.
