Power, Temperature and Noise
Activating more cores and running a substantially higher memory clock is all well and good for performance, but there is an inevitable price to pay with respect to energy consumption. As a system, the GTX 780 Ti consumes about 40W more than a GTX Titan.
Nvidia's power-control mechanism still tries to keep the GPU running at what it deems a safe temperature, which is about 80°C. No 95°C shenanigans here, eh, AMD?
And by using the same cooling design as present on GTX Titan and GTX 780, the one downside is that, under full tilt, the GTX 780 Ti is a little louder. Our logs show the fan spins at around 2,500rpm, compared to 2,200rpm for the Titan when running the same load.
