GeForce RTX 4090

The GeForce RTX 4090 is NVIDIA's flagship Ada Lovelace graphics card and the fastest consumer GPU of its generation, launched in October 2022. It succeeded the RTX 3090 Ti with a performance increase that left no ambiguity about its position at the absolute top of the consumer market.

The RTX 4090 is built around 24GB of GDDR6X memory on a wide 384-bit bus, delivering the highest memory bandwidth in its class. It houses third-generation RT cores, fourth-generation Tensor cores, and full DLSS 3 support including Frame Generation — which was exclusive to Ada Lovelace at launch. Hardware AV1 encoding is also included. Its 450W TDP means it requires robust system cooling and a high-wattage power supply; a 16-pin power connector is standard.

The RTX 4090 is designed for demanding 4K gaming with ray tracing at maximum settings, as well as GPU-accelerated professional workloads including 3D rendering, video production, and local AI inference. It targets high-end enthusiasts and professionals for whom no other consumer GPU option is sufficient.
