Gigabyte GeForce GTX 650 Ti Boost OC 2GB (GV-N65TBOC-2GD)

Gigabyte offers two GeForce GTX 650 Ti Boost models. Both are pre-overclocked (“OC”) but differ in the amount of onboard memory. We’ve got the GV-N65TBOC-2GD version with 2 GB of memory. You can find a lot of information about the card and its cooler on the back of the pretty cardboard box.


The accessories only include a disc with drivers and utilities, a power cable, and a brief installation guide.

The graphics card is manufactured in China and costs $170. Its warranty period is 3 years.

The Gigabyte GeForce GTX 650 Ti Boost OC looks completely different from the previous two cards. Its PCB is blue and its cooler is the original WindForce 2X.

The card looks very attractive. It is about the same size as the reference sample (without the sticking-out pipes and the casing with fans): 242x110x37 mm.

The video outputs, power and MIO connectors are all the same as on the reference GeForce GTX 650 Ti Boost.


Judging by the component layout, the PCB follows the reference design but we can see a row of additional low-RDS MOSFETs next to each standard power phase:

Gigabyte’s Ultra Durable 2 technology means that the graphics card is equipped with premium components such as Japanese solid-state capacitors and ferrite-core chokes. By the way, the PCB is very much alike to the PCB of the more advanced Gigabyte GeForce GTX 660 Ultra Durable card.

The GPU is the same revision as the GPUs of the two previous cards but its manufacture date is the 7th week of 2013. It is clocked at 1033 MHz in 3D mode (boostable to 1098 MHz).


Like the cards from EVGA and Nvidia, the Gigabyte carries 2 gigabytes of onboard memory but the chips are manufactured by Hynix. Labeled H5GQ2H24AFR R0C, they have a rated clock rate of 6000 MHz. They are clocked at the rated frequency here:

The WindForce 2X cooler is exactly the same as on the Gigabyte GeForce GTX 660 Ultra Durable.

It consists of an aluminum base, four 6mm heat pipes soldered to the base and piercing the heatsink’s slum aluminum fins, and a glossy plastic casing with two 92mm fans.

The fans are PWM-regulated in a speed range of 1000 to 2500 RPM.

Compared to the reference cooler from Nvidia and the customized cooler from EVGA, the WindForce X2 is just brilliant. With the fans regulated automatically, their speed was no higher than 1830 RPM whereas the GPU temperature was never higher than 60°C. It is 20°C better in comparison with the two previous coolers.

Auto fan mode

Maximum fan speed

If the speed of the fans is set at the maximum, the temperature lowered by an additional 4°C. With such an efficient cooler, you can overclock the graphics card without apprehensions about its health. In our case, we managed to speed the Gigabyte GeForce GTX 650 Ti Boost OC up by 80 and 960 MHz in terms of GPU and memory frequency, respectively.

The resulting frequencies were 1113/1178/6968 MHz.

The GPU of the overclocked card was 3°C hotter but the peak speed of the fans didn’t change.

So, the Gigabyte GeForce GTX 650 Ti Boost OC is head above the cards from Nvidia and EVGA. And what about the remaining cards?
