Gigabyte GeForce GTX 1660 Gaming OC 6G

The Gigabyte GeForce GTX 1660 Gaming OC 6G is very similar to the Gigabyte GeForce GTX 1660 OC 6G. Its primary difference is that it comes with an extra fan for a total of three Windforce fans. Due to the added cooling capacity, Gigabyte has also increased the factory overclock on the Gaming OC version. 

Gigabyte GTX 1660 Gaming OC Overview

The GTX 1660 lineup from Gigabyte consists of four cards, with the main difference being the amount of factory overclocking (if any) and number of fans. In this triple-fan Gaming OC model, the boost clock reaches 1860 Mhz out of the box – a 4% boost compared to the stock clock. This is the highest factory OC in Gigabyte’s lineup. In comparison, the dual-fan card is boosted from 1785 MHz to 1830 MHz (boost clock).

There’s also a single-fan Gigabyte GTX 1660 that boosts to 1800 Mhz. Gigabyte has not modified the memory clocks on any of the cards, so the 6GB of GDDR5 VRAM runs at 8,000 MHz (effective), and the memory bandwidth is 192GB/s. Like the dual-fan model, the Gaming OC is equipped with a protective backplate. 

Much like other graphics cards based on the TU116/GTX 1660 GPU, the Gaming OC requires a single 8-pin PCI power cable (TDP: 130 W). The card has a single HDMI port and three DisplayPort outputs. 

Performance and Features

Nvidia’s Turing architecture is more efficient than its predecessor Pascal. It also comes with new features such as a larger cache per CUDA core, variable-rate shading, and other optimizations.

The above graph is based on averages from a variety of systems running the GTX 1660 and other cards. Since the Gigabyte Gaming OC comes with a rather large overclock (4%), it should perform a bit better than the average GTX 1660, not least thanks to the triple-fan cooling solution.

Reviews

Guru3D:

… Gigabyte offers a good factory tweaked product here. The performance while easily is tweaked higher heights that other premium AIB cards also offer.

Tomshardware:

… While we’re typically not proponents of spending more money than necessary on mainstream GPUs, this is one model worth its modest premium.

eTeknix:

… For those looking for big performance on a budget, it’s a fantastic deal. 

Based on the reviews, we’ve listed this card as the best GTX 1660 on the market at the time of writing.
