It's odd to see a new range of graphics card architecture being kicked off with one of their lowest end cards, and without its own new numbering system. The higher end 700 series from Nvidia such as the 780 Ti, the 770 and the 760 all use the previous Kepler architecture, whilst the recently released 750, and 750 Ti run on the next generation Maxwell architecture. Usually we see the next generation of cards fronted by the most powerful card of that series. The 600 series brought us the 680 and 670 first, with the lower end models arriving weeks later.
However, this release perhaps shows us just how power efficient the new Maxwell range will be. We know Nvidia have been working on improving the power efficiency of their cards for some time now with various projects such as 'Green Light', and it's great to see their hard work is really starting to pay off.

Asus' dual fan cooler has proven itself significantly over the years. We see it as one of the best non-reference design coolers you can buy. It offers great performance, whilst keeping quiet too. The abilities of this cooler should be extenuated with ultra efficient cards like this that produce little heat in the first place. We're expecting the dual fan cooler to be able to keep the 750 Ti at great temperatures without the fans even needing to fully spin up.
This is the first of the non-reference 750 Tis that we've taken a look at and in terms of aesthetics we are impressed. The reference 750 Ti didn't offer us much to look at. A rather standard PCB with a standalone core-only cooler. We're sure considering how efficient the 750 Ti is that more probably isn't necessary, but it's a real shame after using the lovely reference coolers such as the Titan cooler on other cards that they've taken a big step back on the reference and not even put a shroud on it. However, this actually better shows the differences in aesthetics between the reference cooler and Asus' design. Despite the dual fan cooler being nothing new as we've seen the same cooler on Asus' cards for several generations now, it still is a greatly proven solution that looks really good too.
Asus have made their own PCB for the 750 Ti. The reference card didn't extend beyond the PCIE slot connector at all, whilst Asus have extended the PCB another inch or so further. Considering the size of the cooler on the card, this was a necessary step since otherwise the cooler would have continued well past the end of the PCB which wouldn't have looked right. With the extra inch or so added, the cooler only extends a little past the card which doesn't detract from aesthetics so much. The custom PCB also adds super alloy power components which will significantly increase the lifespan and also should slightly boost performance.
It's worth noting the exceptionally high core clock speeds on this card, with a boost clock of 1150MHz, which is significantly higher than any lower end card that we've seen before. In fact, this is actually significantly higher than most high end cards from the 700 series. The GTX 780 Ti only offers a boost clock of 928MHz. This shows us incredible promise for Maxwell cards in the future. This also offers 2GB of VRAM, which is clocked at 1350MHz which is actually a little lower than we've seen on the higher end 700 series cards. We'll put this down to the 750 Ti being a lower end card however, and for the resolutions and settings you're likely to be running on this card, it probably won't make too much difference.
As it was so efficient, the reference design 750 Ti managed to run from the power from the PCIE slot connector alone. Asus' versions does require a little extra juice to run, and so we find a single 6 pin connector on the top of the card. Interestingly, this is close to the I/O bracket, rather than the end of the card. This isn't something we've seen before, and we do have to say it will make cabling quite a lot harder. As well as this, the Asus dual fan 750 Ti also adds a VGA port which is something we haven't seen in a long time, but it may be useful for those still running older or lower end monitors.
We have to say we like the direction Nvidia have taken with the 750 Ti. Its amazing power efficiency and high clock speeds are great to see. The reference design card didn't show much in terms of aesthetics or cooling performance, and we do believe Asus have corrected that on their dual fan 750 Ti.
Thanks to Asus for providing the card. You can discuss your thoughts on the OC3D Forums.
