GeForce GTX 750 

So take NVIDIA's improvements today and factor in the additional improvements from a 20 nm production process and we could see a new breed of high-end GPUs from the company that uses less power than existing mid-range GPUs today (think of a 100 W Titan).

You'd normally just increase clocks until the card becomes unstable; now, you have to carefully go up in steps, measuring performance every time, to find out where the drop occurs.

The GTX 650 at $100 is a much better deal and the GTX 650 Ti Boost was only $130 before it was pulled off the market, and it came with much better performance and was also very quiet.

It is a quantum leap forward in GPU technology, not because of its performance, but its performance with very little power consumed.

This particular move is only possible with NVIDIA's power-efficient Maxwell GPU architecture, which almost doubles efficiency compared to previous generations.

This power configuration can provide up to 150W of power.

Even in that configuration, the reference card is very quiet, barely audible in both idle and gaming.

What makes it even more complicated is that not all games load the card the same, so one game might still boost, while another game drops the card to its base clock.

In-game, you will experience a mix of arcade and simulation, paired with stunning graphics and flashbacks to get you back on the road quickly.

I also found the empty solder pads for memory chips on the back interesting; 4 GB GTX 750 Ti anyone?

I also found memory overclocking on our sample to be quite limited, worse than other GTX 750 Ti cards using the same memory chips.

The GTX 750 non-Ti comes with 512 shaders instead of the 640 of the Ti, although clock speeds are the same.

Power efficiency is also very important in today's mobile sector because it eats into your battery capacity.

NVIDIA has improved power consumption of their new architecture, but I doubt anyone would have expected such a huge improvement.

Gaming power consumption is still amazing, even though it is increased by the large overclock out of the box.
