The Zotac GeForce RTX 3080 Trinity is a more traditional-looking card with a triple-fan, triple-slot setup.

Graphics Card Dimensions

Dimensions of the card are 32 x 12 cm.

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. Interestingly, the USB-C port for VR headsets, which NVIDIA introduced on Turing Founders Editions, has been removed—guess it didn't take off as planned.

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.

Graphics Card Power Plugs

The card takes in two 8-pin PCIe power connectors. This setup is rated for 375 W.

Multi-GPU Area

The GeForce RTX 3080 does not support SLI. Its bigger brother, the RTX 3090, has SLI support. As both are based on the GA102 GPU, it's purely a segmentation choice. Multi-GPU really isn't supported widely anymore, so it's no big deal.

Teardown

Graphics Card Cooler Front
Graphics Card Cooler Back

Disassembling the Zotac GeForce RTX 3080 Trinity is fairly straightforward. The cooler features seven heatpipes and three 90 mm fans.


Once the main heatsink is removed, a metal frame that provides rigidity for the card becomes visible. It also helps cool the VRM circuitry.


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