Built for 4K gaming and compute

The NVIDIA GeForce RTX 3080 Founders Edition is a graphics card built for 4K gaming and GPU-accelerated workloads. It ships with 10 GB of GDDR6X memory on a 320-bit bus and 8704 CUDA cores. The PCI Express 4.0 x16 interface feeds data to the GPU at up to 19 Gbps effective memory clock. DirectX 12 Ultimate and OpenGL 4.6 support cover modern APIs.

Sustained load behaviour

Under sustained load the GPU runs at a 1440 MHz base clock and can boost to 1710 MHz when thermal headroom allows. The 320-bit memory interface keeps bandwidth steady during long render or compute sessions. Four display outputs — one HDMI and three DisplayPort — drive up to four monitors at 7680×4320 resolution. Driver optimisations maintain stability across extended periods.

Thermals noise and power

The dual-axial flow-through cooler moves air through the heatsink and out the rear bracket, limiting case temperature rise. Fan speed ramps with GPU temperature, staying quiet at idle and increasing only under heavy 3D load. Power is delivered through a 12-pin connector that supports the card's 320 W typical board power. The metal frame and backplate add structural rigidity without extra bulk.

Questions about this item

How much power does the RTX 3080 Founders Edition draw under sustained load?

The card runs at a boost clock of 1710 MHz with 8704 CUDA cores and 10 GB GDDR6X memory at 19 Gbps across a 320-bit interface, so power draw scales with that workload.

What power connector and PSU headroom does the RTX 3080 Founders Edition require?

It installs in a PCI Express 4.0 x16 slot and draws auxiliary power through the onboard connector; ensure your supply has the correct cable and sufficient wattage for the full system.

Will the RTX 3080 Founders Edition work in a motherboard limited to PCI Express 3.0?

The interface is PCI Express 4.0 x16 and is backward compatible with 3.0 slots, though bandwidth-heavy tasks may not reach the 19 Gbps memory throughput seen on a 4.0 platform.
