Today we are going to compare the two Mid-range nVidia cards: the GTX 750 Ti with Maxwell GPU and the nVidia GTX 660 Ti Kepler GPU. The GTX 750 Ti is basically the first glimpse at NVIDIAs upcoming Maxwell GPUs and it will be quite interesting to see wether a lower end card from a new generation can keep up with a higher end card from the earlier generation.
Lets
take a closer look at the results in the games we tested. In this case we can
see that the GTX 660 Ti is quite a bit faster than the GTX 750 Ti in all benchmarks and games.
In The Elder Scrolls V for example the difference between the GTX 660 Ti and the
GTX 750 Ti is 38 percent and in Sleeping Dogs performance is a massive 53 percent
apart. On
average the GTX 660 Ti is a good 25 percent quicker than the GTX 750 Ti.
One of the first things you will notice when digging for reasons why there is a
25 percent gap between these two cards is the fact, that the GTX 660 Ti 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. Other than that the GTX 660 Ti is an overall more complex
chip boasting 3.54 billion transistors versus 1.87 billion on the GTX 750 Ti.
Translated into Shaders this means, the 660 Ti comes with 1344 shader units
whereas the 750 Ti features 640 shader units. But still, this 43 percent
difference in shader count only accounts for a 25 percent gap. This means that
NVIDIA has definitely been able to increase overall computing efficiency with
the Maxwell, when comparing to Kepler.
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 15 watt less than with the GTX
660 Ti (39 Watts compared to 54 Watts). Under load we notice, that the test setup, equipped with GTX
660 Ti needed
48 watt more. Especially when it comes to energyefficiency the GTX 750 Ti is
running circles around the GTX 660 Ti. In other words: in order to
get 25 percent more performance your entire system will burn about 37 percent
more power when using a GTX 660 Ti instead of a GTX 750 Ti.
At this point we usually compare the prices of the two cards we've put up
against one another. These days the GTX 660 Ti sells for 215 Euro whereas the
GTX 750 Ti costs about 110 Euro. But comparing prices of an entry level card is
a rather tricky thing, since the two cards have different target
audiences and most importantly they are from different generations. But still
looking at this topic you can see that the GTX 750 Ti comes with an excellen
price/performance ratio.
