The Card

Visually, the card looks great, using black with red highlights, which reminds me a bit of earlier ASUS designs. A backplate is included, too. Dimensions of the card are 29.5 x 11.5 cm.


Installation requires two slots in your system.


Display connectivity options include a standard-sized DisplayPort 1.4a, one HDMI 2.0b port, and one DVI port.

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 for G-SYNC, users can enable the feature in NVIDIA's control panel regardless of whether the monitor is certified or not.


Colorful has added a dual BIOS feature on their card, which is accessible through that switch. The second BIOS runs at a lower clock and power limit, but identical fan settings, which doesn't seem all that useful for everyday operation. It's still great as a fallback should something go wrong with a BIOS flash.


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


GeForce GTX 1660 does not support SLI.

Disassembly

Colorful's large heatsink uses three heatpipes to move heat away from the GPU chip.


Once the main cooler is removed, a small VRM heatsink becomes visible. Also visible is a black metal bar near the bottom edge of the card that simply reinforces the board to avoid bending of the PCB—a great and cost-efficient solution.


The backplate is made out of metal and protects the card against damage during installation and handling.


The VRM heatsink looks basic, but can handle the heat output with ease because of the power efficiency of the Turing architecture.
