Conclusion

Lets take a closer look at the results in the games we tested. In this case we can see, that the performance  improvement from the GTX 660 to the GTX750 Ti  in Bioshock Infinite and DIRT Showdown is less than 1 percent but on the other hand the GTX 660 is 26 percent quicker in Sleeping Dogs and 23 percent faster in The Elder Scrolls V: Skyrim. On average the GTX 660 is a good 11 percent faster than the GTX 750 Ti.

One of the first things you will notice when digging for reasons why there is an 11 percent gap between these two cards is the fact, that the GTX 660 ships with 11 percent higher Memory clocks than the GTX 750 Ti. Pair that with a 192 Bit memory interface (128 Bit on the GTX 750 Ti) and you get 66 percent more memory bandwidth in total. Nevertheless it is interesting to see that both these improvements don't make for a larger performance gap than 11 percent. Overall it is interesting to see that the Maxwell chip used with the GTX 750 Ti will be raising the bar by quite a bit.
 
At this point we also want to have a quick look at power consumption. Running our test setup with the GTX 750 Ti made it consume eleven Watt less than with the GTX 660 (39 Watts compared to 50 Watts). Under load we notice, that the test setup equipped with the GTX 660 needed 47 watt more. Especially when it comes to power efficiency the GTX 750 Ti is running circles around the GTX 660. In other words: in order to get 11 percent more performance your entire system will burn about 37 percent more power when using a GTX 660 instead of a GTX 750 Ti.

Things are starting to get really interesting when we add the price to both sides of the euqation. Today you can buy a reference GTX 660 for 140 Euro and a GTX 750 Ti sets you back 110 Euro. This translates into a 27 percent price difference althought the GTX 660 is just 11 percent quicker than the GTX 750 Ti. One could now say, that either the GTX 660 is overpriced or the GTX 750 Ti features a really competitive price tag. But actually the one thing that is for certain concerns NVIDIA's pricing scheme, where high-end cards set you back quite a few bucks extra and sometime you'll have quite a hard time justifying that difference.
