The GeForce RTX 3080 is equipped with 10 Gigabytes of GDDR6X memory and operates at a maximum effective data rate of 19 Gbps. On the following pages, we'll go over the specifics of the device in greater detail. Not a Ti or SUPER model, but the decision was made based on supply and demand. First and foremost, though, is eye candy.

Brown/beige.. sure, you probably need to like that. Each of the card's two 8-pin power headers is capable of delivering 150W, for a total of 300W. Additionally, the PCIe Express slot has a power rating of 75 watts. The overall power rating of the board design is 375 Watt. A microswitch located slightly to the left of the PCIe PEG power connectors lets you toggle between the default (quiet) and OC BIOS modes. We measured a somewhat more aggressive fan RPM mode in Overclocking mode, as well as active fans while the PC is idle. Aside from a slight boost frequency increase, there is little difference between this OC setting and the default in terms of game performance.

The Noctuabranding is immediately apparent upon first glimpse of this card. We do feel the choice made by sticking with the brown color scheme of the Noctua fans, was a good one. We also understand that a lot of people will be disappointed with the final product aesthetics. However, it certainly screams and breathes the Noctua DNA. The cooler extends from the PCB; as you will learn in the teardown, the graphics card PCB itself follows a slightly large form factor that is 31cm in length.  The rest of the real estate (and that is a large premise!) used is for cooling, based on a dual-fan cooler. The backplate has plenty of little air gaps, mesh, whatever you want to call it, and is similar to the TUF one. We like that as it allows heat to travel away from the backplate as opposed to trapping it.

Depending on preference, the card can look bad upwards to fabulous depending on your subjective opinion. The Noctua card comes equipped with a dual-BIOS feature, which is provided by ASUS. Although the "quiet" BIOS is the default setting, switching to the "performance" BIOS will result in a more aggressive fan curve that produces lower temperatures (at the expense of more noise). Projections are ~70 Degrees C / 30 DBa for the quiet mode and ~60 degrees C /45 DBa for the performance cooling modus operandus.

The IO panel is also meshed for venting and shows five display connectors, three DisplayPort 1.4, and two HDMI 2.1 connectors that will bring 8K 60 Hz HDR to a single HDMI cable. The card has two fans and uses the traditional power connector design, e.g., 8-pin, but two of them.
