Zotac have become almost synonymous with the word graphics card. They have been at the forefront of the customized graphics card industry for years and even though they also offer mini PCs and motherboards, graphics cards are what many of us still think of when they are mentioned. Today is no exception as we take a look at a lower end offering from Zotac, the GTX 750Ti OC.
The 750Ti comes in a typical Zotac black box with the make, model and version clearly shown. The back of the box has a drawing of the card with the features, minimum system requirements and what is included in the box clearly written out. Inside there’s some product documentation, CD, VGA to DVI dongle and a power cable.
The card occupies two slots with a vent in the I/O shield to let the air out. Two DVI’s, a DisplayPort and HDMI port occupy the rest of the I/O shield. The aluminum heatsink and two orange fans cool the graphics and memory chips. The card has a 6-pin power connector but lacks an SLI connector so the 750Ti is limited to its own capabilities and can’t team up with a second card for extra performance.
The 28nm GM107 core in the 750Ti normally runs at 1020MHz and 1085MHz for core and boost clocks respectively with the 2GB of Hynix GDDR5 memory running at 1350MHz on a 128-bit bus. Zotac’s OC version runs at 1046MHz and 1124MHz for core and boost clocks but the memory remains the same at 1350MHz.
For testing we used our core i7-3770k Ivy Bridge testbed with 2 x 4GB of Gskill Ripjaws RAM in an MSI Z77 motherboard hooked up to a Thortech 850W power supply. For comparison we used the Asus Direct CU II OC 260X. The 750Ti used Nvidia’s 334.89 drivers while the 260X used the Radeon 14.2 beta drivers.
Using Zotac’s own Firestorm overclocking program we managed to increase the core to 1150MHz and the memory to 1435MHz. Even at these speeds the Zotac was able to remain cool at 60C. Running 3DMark 13 Firestorm Extreme, the card managed a score of 2097 which is 152 points over its score at stock speeds.
I think we all knew from the start that this card wasn’t going to break any performance records but you must admit that it has performed quite admirably with what little power it has. If we tone down the settings a bit it is quite possible to play 1080p games reasonably well as long as the minimum framerates go up. The card was kept cool and relatively quiet thanks to Zotac’s dual fan system and should fit easily into a mini PC setup. The Zotac is still a new product on the market and so pricing may not be as accurate and stock not readily available however it is set to go for around 115GBP or 700AED which is on par with other 750Ti cards out in the market today. So the decision all boils down to preference of brand as well as preference of make since AMD’s 260X is floating around that price point as well. The difference between the 750Ti and 260X in these overclocked guises is minimal in most games so ultimately the choice is yours, just as it should be.
