A GeForce RTX 3080 with 10GB GDDR6X on a 320-bit bus, boost clocks up to 1815 MHz and 8704 CUDA cores for 4K gaming
This ASUS graphics card targets gamers and creators who need strong 4K performance. It uses the NVIDIA Ampere architecture with 8704 CUDA cores and 10GB of GDDR6X memory. The board connects through a PCI Express 4.0 x16 slot and includes two HDMI 2.1 ports plus three DisplayPort 1.4a outputs for up to four displays.
The 10GB frame buffer on a 320-bit bus running at 19 Gbps handles high-resolution textures and ray-traced scenes at 4K. In modern titles with maximum settings the memory can fill up, forcing texture streaming or lower detail levels. The 1815 MHz OC boost clock and 1785 MHz gaming clock provide headroom for sustained frame rates before thermal limits throttle performance.
The PCIe 4.0 x16 interface delivers full bandwidth on compatible platforms; older PCIe 3.0 systems will see reduced throughput. Maximum digital resolution is 7680 x 4320 over these interfaces. HDMI 2.1 and DisplayPort 1.4a set the practical refresh-rate ceiling for 8K and high-refresh 4K panels. SLI is not supported, so multi-GPU scaling is unavailable.

Yes, the card is backward compatible with PCI Express 3.0 motherboards and will operate at 3.0 speeds until a 4.0 platform is installed.
Open GPU Tweak II or a similar monitoring tool and observe the core frequency under load; it should report 1815 MHz when OC mode is selected.
The card itself provides the video outputs; no video cables or adapters are bundled, so you must supply your own HDMI 2.1 or DisplayPort 1.4a cables.
