The Card

The Gigabyte GTX 1660 SUPER Gaming OC looks a class above thanks to its large cooling solution and backplate.


Dimensions of the card are 28 cm x 11 cm.


Installation requires two slots in your system.


Display connectivity options include three standard DisplayPort 1.4a and an HDMI 2.0b.

NVIDIA has updated their display engine with the Turing microarchitecture, which now supports DisplayPort 1.4a with support for VESA's nearly lossless Display Stream Compression (DSC). Combined, this enables support for 8K@30Hz with a single cable or 8K@60Hz when DSC is turned on. For context, DisplayPort 1.4a is the latest version of the standard that was published in April, 2018.

At CES 2019, NVIDIA announced that all their graphics cards will now support VESA Adaptive Sync (aka FreeSync). While only a small number of FreeSync monitors have been fully qualified with G-SYNC, users can enable the feature in NVIDIA's control panel regardless of whether the monitor is certified or not.


The board uses an 8-pin power connector. This input configuration is specified for up to 225 watts of power draw.


GeForce GTX 1660 Super does not support SLI.

Disassembly

The WindForce 3X cooling solution by Gigabyte features three aluminium fin stacks that are skewered by three copper heat pipes that make direct contact with the GPU at the base. The heatsink also handles cooling of the memory chips and VRM circuitry. Three 80 mm fans provide airflow.


The backplate is made out of plastic, and while it won't contribute towards cooling, it will provide stability, improve the look, and protect the card against damage during handling and installation.
