Palit GeForce GTX 660 Ti JetStream 2GB (NE5X66TH1049-1043J)

We review Palit products on a regular basis and now we’ve got their GeForce GTX 660 Ti JetStream. If the size of the graphics card’s box mattered in choosing the best product, the Palit would win immediately as its box is the largest of all.


It is the third time that we see the same design of the back of the packaging: some designers just don't take the trouble of creating something original. The top of the box can be opened to reveal both the graphics card and exhaustive information about it.

The accessories include two adapters, a power cable and a disc with drivers:

Manufactured in China, the Palit card costs $299 and has a 1-year warranty.

Palit’s JetStream design is easily recognizable for its plastic casing with two translucent fans and a hieroglyph in between.


The graphics card isn’t long at only 245 millimeters but higher than the rest of the products at 49 millimeters. You won’t be able to use this model in SLI mode if there’s only one expansion slot between your mainboard’s graphics slots.

As usual, we have two 6-pin power connectors, two MIO connectors, and a standard selection of video outputs:

It’s the fourth time that we see this PCB design today. It is a copy of the reference sample.

The Palit carries somewhat different power components than the EVGA and Inno3D cards but the power system follows the same formula: 4+2+1 phases.

Like the other GPUs, this 28nm chip comes from Taiwan. It is revision A2 and was manufactured on the 13th week of 2012 (March-April).

Its base and boost clock rates are 1006 and 1085 MHz, respectively. According to our monitoring tools, the GPU was clocked at up to 1150 MHz at high loads.

As opposed to all the previous products, the Palit’s 2 GB of onboard memory is pre-overclocked. Not much, though. The frequency is only increased by 100 MHz to 6108 MHz. Of course, they didn’t have to use some other chips for that, so we can see the same Hynix H5GQ2H24AFR R0C memory here:

The Palit GeForce GTX 660 Ti JetStream specs can be viewed in this GPU-Z screenshot:

The graphics card is equipped with the same cooling system as we saw on the Palit GeForce GTX 670 JetStream: an aluminum heatsink with three 6mm copper heat pipes and a plastic casing with two fans.


There is a tall aluminum heatsink with thermal pad on the power system components. Like the MSI card, the Palit uses fans from Power Logic (part number PLA09215S12H).

With PWM-based regulation, they can rotate at 900 to 2900 RPM.

The Palit is comparable to the other products in this review in terms of the operating temperature: 71°C in the automatic fan regulation mode and only 55°C at the maximum speed of the fans.

Notwithstanding the reference PCB design, the lack of newfangled technologies and the modest cooler, our sample of the Palit GeForce GTX 660 Ti JetStream could be overclocked by 135 MHz (the best result in this review) and 1200 MHz in terms of GPU and memory frequency, respectively.

The resulting frequencies were 1141/1220/7308 MHz:

Moreover, the peak GPU frequency was as high as 1285 MHz at high loads, which is the second best result after the Gigabyte.

The overclocked Palit had a rather high temperature: 77°C at 1470 RPM.

Now we’ve got only one product left. It is a Zotac.
