The Gainward GeForce RTX 3080 Ti Phantom GS is dominated by a black color theme. A beautiful highlight are the two dark glossy metal pipes that run along the top and bottom of the cooler. On the back, you'll find a high-quality metal backplate with cutouts to let some airflow through.

Graphics Card Dimensions

Dimensions of the card are 30.0 x 14.0 cm, and it weighs 1581 g.

Installation requires three slots in your system.

Monitor Outputs, Display Connectors

Display connectivity options include three standard DisplayPort 1.4a and one HDMI 2.1. The DisplayPort 1.4a outputs support Display Stream Compression (DSC) 1.2a, which lets you connect 4K displays at 120 Hz and 8K displays at 60 Hz. Ampere can drive two 8K displays at 60 Hz with just one cable per display.

Ampere is the first GPU to support HDMI 2.1, which increases bandwidth to 48 Gbps to support higher resolutions, like 4K144 and 8K30, with a single cable. With DSC, this goes up to 4K240 and 8K120. NVIDIA's new NVENC/NVDEC video engine is optimized to handle video tasks with minimal CPU load. The highlight here is added support for AV1 decode. Just like on Turing, you may also decode MPEG-2, VC1, VP8, VP9, H.264, and H.265 natively, at up to 8K@12-bit.

The encoder is identical to Turing. It supports H.264, H.265, and lossless at up to 8K@10-bit.


This ARGB header lets you connect your motherboard's RGB output to the graphics card to synchronize it with the rest of your system.


Near the ARGB header, we spotted these four measuring points for various voltages on the card.

Graphics Card Power Plugs

The card has three 8-pin power inputs. This configuration is rated for up to 525 W of power draw.

Multi-GPU Area

The GeForce RTX 3080 Ti doesn't support multi-GPU.

Teardown

Gainward's heatsink uses six heatpipes that provide cooling for the GPU, memory, and VRM circuitry. The thermal pads on memory are 0.75 mm thick, and those on the VRM are 1.0 mm thick.


The backplate is made out of metal and protects the card against damage during installation and handling. Thermal pads on the backplate are 2.0 mm thick.
