ASUS TUF Gaming GeForce RTX 4090 24GB GDDR6X

The ASUS TUF Gaming GeForce RTX 4090 is a graphics card built on the NVIDIA Ada Lovelace architecture. It targets enthusiasts and professionals who need maximum frame rates at 4K and 8K resolutions. The card connects via a PCI Express 4.0 interface and features a triple-fan cooler with a metal exoskeleton for structural rigidity. It is designed for sustained heavy workloads in gaming and content creation.

24GB GDDR6X memory and 384-Bit interface capacity

The card provides 24GB of GDDR6X memory across a 384-bit bus, delivering high bandwidth for 4K and 8K gaming. This capacity handles large texture packs, complex ray-traced scenes, and multi-application workflows comfortably. In extremely demanding scenarios with maximum ray tracing and high-resolution assets, the 24GB frame buffer can become a limiting factor. The 450W thermal design power requires a robust power supply and case airflow to maintain boost clocks.

PCI Express 4.0 and display output limits

The PCI Express 4.0 interface provides sufficient bandwidth for current gaming and compute tasks, though it does not reach the theoretical ceiling of newer standards. Display outputs include two HDMI 2.1 ports and three DisplayPort 1.4a connectors, supporting up to four monitors at a maximum resolution of 7680 x 4320. HDMI 2.1 enables high-refresh 4K and 8K displays with variable refresh rate. DisplayPort 1.4a drives high-refresh panels up to its transmission limit.
