Power And Temperature
With a single 250 W graphics card instead of two 195 W models, this quarter's effort is guaranteed to use less power under a graphics load. The CPU shouldn't reflect much of a change, either, since both PCs employ quad-core Haswell-based processors.
Indeed, the Q1 2014 build remains under 475 W, even when I overclock it. A quick look at the CPU under load shows both platforms faring similarly, though the previous build's Core i5-4670K manages to idle at a significantly lower wattage. That could be a platform issue, where the board I'm using today isn't dropping to the same idle states.
The thermals are comparable between both machines, except for the GeForce GTX 780 Ti's higher temperature under load. We're not entirely surprised. After all, the 780 Ti leans on a big GK110 that uses more power than the smaller GK104 on Nvidia's GeForce GTX 770. Our overclocked 780 Ti's temperature drops quite a bit, which makes sense in light of our manual fan speed increase to prevent throttling.
