Gigabyte GeForce GTX 750 (GV-N750OC-1GI) Video Card Review

The Gigabyte GV-N750OC-1GI (Cont’d)

The Gigabyte GV-N750OC-1GI has four connectors: two HDMI, one DVI-D, and one DVI-I, actually supporting four displays at the same time.

The Gigabyte GV-N750OC-1GI uses a cooler with a 100 mm fan, bigger than the cooler used by the NVIDIA reference card. This cooler does not touch the memory chips. As mentioned, the GeForce GTX 750 has a TDP of 55 W, but on the analyzed card GPU runs at a higher clock rate, and Gigabyte does not inform the TDP for this card.

The PCB is 5.7” (145 mm) long, but the whole card has 7.3” (185 mm), thanks to the bigger cooler.

The video card uses a voltage regulator with two phases for the GPU and one phase for the memory chips. The voltage regulator circuit uses a digital design and is controlled by a µP1542 chip. All capacitors are solid.

The reviewed video card uses four Elpida W2032BBBG-60-F GDDR5 chips, each one storing 2 Gbits of data, comprising the 1 GiB of memory available on this video card. These chips can run up to 6 GHz. On this video card, they are accessed at 5 GHz, which means there is a good margin for safely increasing the memory clock.

Before seeing the performance results, let’s recap the main features of this video card.
