NVIDIA GeForce RTX 3080 Founders Edition graphics card

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.
