Overclocking

To see how much performance the GTX 650 Ti Boost 2GB had left, we opened up EVGA Precision for a bit of overclocking. With the power limit set to the maximum allowed by the program, we eventually settled on a core clock speed of 1,135MHz. This represents a 155MHz boost, or 16 percent, over stock speeds, and required a voltage of 1,050mV to keep it stable. However, thanks to Nvidia's GPU Boost technology, the card actually fired up to 1,202MHz in use, which is an excellent result.

As for the card's memory, we were able to add 130 MHz (520MHz effective) for a final memory clock speed of 6.528GHz effective and a total memory bandwidth of 156.7GB/sec. Both the core and memory overclocks are more than what we were able to achieve with the GTX 660 2GB, so board partners should have plenty of room to play with for custom editions of the GTX 650 Ti Boost 2GB. We re-ran the 2,560 x 1,600 Battlefield 3 and Crysis 3 tests as well as the Unigine Heaven 3.0 Benchmark to assess the resultant performance increase.
