Product overview
Released on October 12, 2022, the GeForce RTX 4090 is NVIDIA’s Ada Lovelace flagship. It sits at the very top of the GeForce stack, built to deliver uncompromised 4K play and creator throughput beyond lower‑tier cards.
With 16,384 CUDA cores and 24 GB of GDDR6X on a 384‑bit bus, it’s well‑suited to 4K gaming with heavy ray tracing (with DLSS frame generation), accelerated content creation/rendering, and local AI/ML work. Founders Edition cards are rated for 450 W (NVIDIA recommends an 850 W PSU), use a 16‑pin PCIe Gen5 power input (adapter included), and provide 1x HDMI 2.1a plus 3x DisplayPort 1.4a outputs. The reference design is a triple‑slot, ~304 mm card, so check case and cable clearance.
