After weeks of teases, Nvidia's next generation of computer graphics cards is here: the "Ada Lovelace" generation of RTX 4000 GPUs. Nvidia CEO Jensen Huang debuted two new models on Tuesday, complete with prices and release windows: the RTX 4090, which will start at a whopping $1,599, and the RTX 4080, which will launch in two configurations.

The pricier card, slated to launch on October 12, occupies the same highest-end category as the company's 2020 megaton RTX 3090 from 2020 (previously designated by the company as its "Titan" product). Its jump in physical size will demand three slots on your PC build of choice. The specs are indicative of a highest-end GPU: 16,384 CUDA cores, up from the 3090's 10,496 CUDA cores, and 2.52 GHz of boost clock, up from 1.695 GHz on the 3090. Both of these 4090 jumps perform within the same 450 W power envelope as the 3090. Its RAM allocation will remain 24GB of GDDR6X memory.
