The Card

Visually, the Gigabyte RTX 5080 Gaming OC looks very similar to previous generation cards from the company, the main color theme is gray with various highlights. On the back you get a metal backplate with a large cutout.


Dimensions of the card are 34.0 x 14.0 cm, and it weighs 1823 g.


Installation requires three slots in your system. We measured the card's width to be 70 mm.


Display connectivity includes three standard DisplayPort 2.1b and one HDMI 2.1b.

Standard for all GeForce RTX 50-series Blackwell cards is a new display engine that supports three DisplayPort 2.1b outputs, each capable of UHBR20; and one HDMI 2.1a. Both interfaces support DSC (display stream compression). With DSC enabled, a single DisplayPort on this card can drive 4K 12-bit HDR at 480 Hz; or 8K 12-bit HDR at up to 165 Hz. The RTX 5080 features an updated media acceleration engine with support for 4:2:2 video formats, AV1 UHQ, and MV-HEVC. There are two independent NVENC and NVDEC units.


The card uses a single 16-pin connector, which allows a maximum power draw of 600 W.


Gigabyte has added RGB illumination zone on the logo and behind the three fans.

Teardown

Gigabyte's thermal solution uses nine heatpipes and a vapor-chamber baseplate. It provides cooling not only for the GPU, but also for the memory chips and VRM circuitry. Note the use of thermal putty instead of thermal pads, which makes maintenance hard, because you'll probably have to replace everything every time you take the card apart.


The backplate protects the card against damage during installation and handling.


This BIOS switch lets you select between the default "Performance" BIOS and a "quiet" BIOS that runs a more relaxed fan curve.
