NVIDIA are a name that is synonymous with gaming, having conquered the graphics card market several times with absolute behemoth graphics cards, but today we are going to be looking at something that you won’t need to remortgage your house in order to purchase, the NVIDIA GTX 750.
As I start to write this the GTX750 has just literally just landed on my desk, courtesy of NVIDIA. The new 750 and 750ti cards are designed to slot in just above the GTX 650 in NVIDIAs graphics card line up. So it is targeting the mid-range gaming market, where performance to play most games at a decent frame rate is key, but potentially with not all the eye candy turned on.
The GTX 750 uses the newly launched Maxwell architecture, which is the successor to the previous Kepler architecture of the 6 series cards, it generally means the card will have a lower power requirement for the same amount of performance, the card we are going to be using here does not actually require any additional power.
As a break from a normal review, I am going to do a short round up of card performance and put the GTX750 against the cards it will be competing with and the card it will replace, so this will include a GTX650 from Gainward which is a 2GB variant, a GTX650ti OC model from Gigabyte, specifically a 2GB Windforce variant, the third and final card I will be testing against is a Palit GTX660, again, another 2GB variant card. These cards retail for £115 and £129 respectively, so it will be interesting to see how the GTX750 performs and how it competes in price to these already well entrenched cards.
NVIDIA GTX 750
The GTX 750 we are using is a standard OEM model from NVIDIA, so unsurprisingly the card is not overclocked, and comes with one of the most basic looking coolers I have seen. It features a standard green PCB, and connector wise you are covered with a DVI-D, DVI-I and a mini HDMI port on a single slot, the card itself is not a single slot card however, as the aforementioned cooler is just a bit too tall, and may slightly interfere with the other cards you may have fitted.
Specification Wise the card features 512 CUDA cores, 42 TMUs and 16 ROPs whilst also coming fitted by default with 1 GB of GDDR5 memory hooked up to a 128bit memory bus, this allows for 80.2GB/s bandwidth on the card. The Core clock sits at 1020 MHz and the memory is clocked at 1253 MHz
The GTX 660 is a popular mid-range card and has a lot of performance which makes it one of the most popular cards that CCL currently stock, the card features a large single fan cooler, and has a shroud which helps to direct the airflow over the card, which means that it takes up two slots it also requires an additional single 6-Pin PCI-Express power connector. The outputs on the Palit GTX660 consist of a DVI-D, DVI-I, a full size HDMI and a full size Display port.
Specification wise this card features 960 CUDA cores 80 TMU’s and 24 ROPS unlike the GTX750 it comes fitted with 2GB of GDDR5 memory and a 192bit memory bus, allowing for a higher bandwidth of 144.2GB/s. By default the core clock is 980 MHz, but can it can automatically GPU boost to 1033 MHz and the memory is rated at 1502 MHz.
Gigabyte GTX 650Ti OC
The GTX650ti is a special beast, being one of the pre overclocked models available from Gigabyte, because of this it means that it is fitted with one of their very good dual fan Windforce coolers; again this is a two slot cooler and actually extends beyond the graphics cards mainboard. This card also takes an additional single 6-Pin PCI-Express power connector. The outputs on this card differ to the two previous, having two DVI-D connectors, a VGA and a full size HDMI.
Specification wise this card features 768 CUDA cores, 64TMU’s and 16 ROPs. This model comes fitted with 2GB of GDDR5 memory, and much like the GTX 750, a 128 Bit memory bus; as the memory is not overclocked (it stays at 2700Mhz-) on this model it means the bandwidth is 86.4GB/s. The core clock is 1032 MHz which is slightly higher than the normal 928 MHz
The GTX650, is the card that the GTX750 is effectively replacing, the card we are using is a Gainward 2GB model, by naming scheme the GTX 750 is the new version of this card, but the new architecture included should mean that it is more than just a rebrand.
Specification wise this card features 384 CUDA cores 32 TMU’s and 16 ROPS like the other non reference cards it comes fitted with 2GB of memory and has a 128bit memory bus, allowing for a bandwidth of 80GB/s. By default the core clock is 1059 MHz and the memory is rated at 1250 MHz.
Based on specifications alone, I expect the GTX 660 should be top of the bunch just simply because of the additional power it has. It has both more CUDA cores and a higher memory bandwidth than the other cards, but it will be interesting to see how the GTX 750 compares to the GTX 650Ti OC and GTX 650 granted the latter’s seemingly lower specifications.
