GeForce® GTX 1660 OC 6G GV-N1660OC-6GD

Gigabyte GeForce GTX 1660 OC 6G, Model # GV-N1660OC-6GD

The GeForce GTX 1660 is NVIDIA's new sweet spot graphics card that delivers exhilarating performance at a budget-friendly price. Based on the award-winning Turing architecture, this card packs 1,408 CUDA Cores and 6GB 192-bit GDDR5 RAM, and consumes merely 120W power (maximum power for reference model). It turns your computer into a gaming machine, capable of playing today's most popular games smoothly.

The Gigabyte GV-N1660OC-6GD card is factory overclocked to 1830 MHz Boost frequency (reference card is 1785 MHz) for more performance out of the box. Its WINDFORCE 2X cooling solution is quiet and efficient, and two 90 mm fans use semi-passive design which stops the fan completely in low load or idle status. A backplate gives the card a solid look and enhances the structure rigidity. And the Ultra Durable components guarantee unbeatable stability, reliability and long lifespan you would expect from Gigabyte.

The WINDFORCE 2X cooling system features two 90mm unique blade fans, an alternate spinning fan, a composite copper heat-pipe direct-touch GPU and 3D active fan functionality. All together, these technologies deliver and support an effective heat-dissipation capacity for higher performance at lower temperatures.

GIGABYTE's patented “Alternate Spinning” is the only solution for properly handling the turbulent airflow of adjacent fans. Since the adjacent fans rotate in the same direction, the airflow direction becomes opposite between the fans, causing turbulent airflow and reducing heat-dissipation efficiency. GIGABYTE turns the adjacent fans in the opposite direction so that the airflow direction between the two fans becomes the same, reducing turbulence and enhancing airflow pressure.

This card's airflow is spilt by triangulated fan edges that guide everything smoothly through the 3D-stripe curves on each fan's surface, effectively enhancing overall airflow.

The 3D Active Fan provides semi-passive cooling so the other fans will remain off when the GPU is in a low load or low-power game. It allows gamers to enjoy gameplay in complete silence when the system is running light or idle. The LED fan indicator on the top of the graphics card provides an instant display of the fan status.

The shape of each pure-copper heat pipe maximizes the direct contact area with the GPU, ultimately enhancing heat transfer. Each heat pipe also covers the VRAM through a large metal plate contact to ensure proper cooling.

The composite heat-pipes combine thermal conductivity and phase transition to efficiently manage the heat transfer between two solid interfaces, increasing cooling capacity.

Extreme durability and overclocking

This graphics card uses an 4+2 power-phase design to allow the MOSFET to operate at lower temperatures. The over-temperature protection design and load balancing for each MOSFET, plus the Ultra Durable certified chokes and capacitors provide excellent performance and longer system life. (Reference card is 3+1 power phase).

The cutting-edge intuitive interface allows you to adjust the clock speed, voltage, fan performance and power target in real-time according to your game’s requirements.

Solid card, good performance, quiet 4/21/2020 11:24:22 AM

Pros: Card installed cleanly and runs quietly. Performance is good. Its nicely constructed and seems solid.

Cons: Required an 8 pin power adapter, where as the previous card used 2x 6-pin. It'd have been nice if it'd included the adapter to go from 2x 6 to 8. (Both are rated to provide the same power.)

Overall Review: A good performing, solid, quiet video card. Pretty much exactly what I was looking for.

gigabyte gtx 1660 6gb ddr5 11/13/2019 12:07:07 AM

Pros: works
decent price
decent performance

Cons: Nvidia releasing the 1660 "super" for roughly the same price just months later. To have 8gb of gddr6 instead of 6gb of gddr5 would be nice. I'm "super" annoyed.

Overall Review: great performance per dollar

Great card for all gaming. 7/9/2019 7:43:03 AM

Pros: -Quiet
-3 DP

Cons: -Large (Long)
-Buggy Drivers?

Overall Review: I had some issues when i originally installed the card with the screen randomly going black for a few seconds. They've gotten fewer and far between with each Graphics Driver update, so I'm assuming it's just some bugs they are working out. This, the length, and the fact that I'm old school and like DVI is why i give it 4 eggs.

All in all, great card, would buy again. Nice for a budget rig without giving out on any performance.

Avg. gamer card 7/1/2019 3:54:33 PM

Cons: No Cons ATM

Overall Review: I would recommend this product the Avg. gamer but not to a gamer looking for the high FPS boost. It's basically a 1060 Ti. Nothing wrong with it at all and it performs well and can play high to ultra on many cards keeping a 60+ avg. I would only buy this again if I was building a computer for my kids.
