As expected, Nvidia have announced the GeForce RTX 4090 during their GeForce Beyond livestream – and confirmed the RTX 4080 for good measure. Both GPUs are based on Nvidia’s new Ada Lovelace architecture, and will launch this year: the RTX 4090 on October 12th, and the RTX 4080 sometime in November.
Key features of Ada Lovelace, and thus these new cards, include 3rd Gen RT cores, 4th Gen Tensor cores, and a new streaming multiprocessor. These supposedly add up to twice the performance of Ampere (that’s the RTX 30 series architecture currently dominating our best graphics card guide) in standard rasterised games, and up to four times the performance in ray traced games. And since Nvidia were clearly in a ray-tracey mood, they also took the opportunity to reveal Portal RTX: a semi-official mod for the original Portal that upgrades it with RT lighting and reflection effects. Corrrr.
