Built for 4K gaming and creative workloads

The GIGABYTE GAMING OC model pairs the GeForce RTX 4080 SUPER GPU with 16GB of GDDR6X memory on a 256-bit interface. It targets enthusiasts who need high frame rates at 4K resolution and creators who rely on 10240 CUDA cores for rendering and compute tasks. The card occupies 3.7 slots and measures 342 mm in length, requiring an ATX case with adequate clearance.

Sustained load behaviour with WINDFORCE cooling

A triple-fan WINDFORCE cooler dissipates the 320W thermal design power during extended gaming or rendering sessions. The factory core clock runs at 2595 MHz, above the 2550 MHz reference speed, and the memory operates at 23 Gbps effective. Stable output depends on an 850W power supply feeding the single 16-pin connector. Dual BIOS lets you choose between performance and quieter fan curves for long runs.

16GB GDDR6X decides fit for high-resolution work

The 16GB frame buffer combined with 23 Gbps GDDR6X on a 256-bit bus determines whether this card handles your 4K texture sets, large 3D scenes or multi-monitor arrays. Display outputs comprise 1 x HDMI 2.1a and 3 x DisplayPort 1.4a driving up to 7680 x 4320 resolution across four screens. PCI Express 4.0 interface and DirectX 12 Ultimate support complete the feature set.

Spørgsmål om denne vare

How much power does the 320W TDP card draw through its single 16-pin connector during long sessions?

The graphics card has a thermal design power of 320W and draws that power through one 16-pin connector, so your power supply must deliver the full load on that cable.

What power supply wattage and connector does the 16-pin plug require?

The manufacturer recommends an 850W power supply to support the 320W TDP and the single 16-pin power connector on this card.

Will the 342mm length and 3.7-slot width fit alongside my existing ATX motherboard layout?

The card measures 342mm long and occupies 3.7 slots, so verify that your case has enough clearance and that adjacent PCIe slots remain accessible.
