Overclocking
To discover our PNY GeForce GTX 780 XLR8 OC sample’s overclocking abilities we used EVGA’s Precision X software and began raising power and thermal thresholds to the maximum allowed and then increased the voltage by 38mVolts – also the maximum permitted. Then using Unigine’s Valley benchmark we began stability testing.
After much effort we were able to boost performance to a base clock of 1,145MHz. This is an additional 139Mhz over the already impressive factory overclocking settings and an amazing 284Mhz over a reference GeForce GTX 780! This is 13.8% percent performance boost over the already factory overclocked base clock settings and a whopping 32.7 percent improvement over a stock GeForce GTX 780! Put another way, when overclocked this GK110 runs 30.9% faster than a GK110 found in a reference GeForce 780Ti – which will certainly help make up for the 25% fewer enabled Cuda Cores.
On the memory side of the equation we were able to boost the memory to an effective 7490Mhz, which is a 20.7 percent improvement over the card’s default 6208Mhz – an insanely high 24.8% boost over a reference 780’s 6000Mhz – and even a 490Mhz boost over a reference GeForce GTX 780Ti’s memory! Color us impressed.
With such massive improvements in overclocking it came as little surprise to see this GeForce 780 actually outcompete a reference GeForce 780Ti. Considering this bad boy goes for $150 less than a vanilla 780Ti that to us is the epitome of a great value.
