Regardless, the company’s relatively light cooler performs admirably. In Metro: Last Light, we observed the Gaming OC 6G consuming about 133W. Although that’s about 9W more than EVGA’s GeForce GTX 1660 Ti XC Black Gaming, Gigabyte’s card ran a couple of degrees cooler. Moreover, it maintained between 1,890 and 1,920 MHz through our run, whereas EVGA's XC Black Gaming demonstrated a range of 1,785 to 1,815 MHz.
Gigabyte’s 1660 Ti Gaming OC 6G sports a plastic backplate. This plate doesn’t do anything for rigidity, and it certainly doesn’t improve the card’s cooling. The plate may, however, help protect the PCB in case something gets dropped on it.
We approve of Gigabyte’s display output choices. Three DisplayPort connectors and a single HDMI interface cover the most common multi-monitor configurations. Down at this level, VirtualLink support isn’t really necessary. And doing away with DVI yields a freer-flowing grille. Unfortunately, the potential benefit of additional airflow is lost since the cooler’s fins move air perpendicular to the bracket.
What lives under the GeForce GTX 1660 Ti Gaming OC 6G’s hood is already well-known. We dissected the TU116 graphics processor in Nvidia GeForce GTX 1660 Ti 6GB Review: Turing Without The RTX. Gigabyte takes the same chip, with 1,536 CUDA cores, and bumps the typical GPU Boost rating up to 1,860 MHz—a 5% increase compared to the 1,770 MHz we tested from EVGA’s XC Black Gaming board.
Gigabyte GTX 1660 Ti OC card's 6GB of GDDR6 memory moves data at 14 Gb/s, yielding 288 GB/s of aggregate bandwidth on a 192-bit bus.
All of Gigabyte's graphics cards include three years of warranty coverage, and some of them add a fourth year when you register on the company's website. The GeForce GTX 1660 Ti Gaming OC 6G is not one of those special models. In its segment, however, three years of coverage is fairly standard.
