NVIDIA's next-generation GeForce RTX 4090 gaming graphics card is rumored to be more than twice as fast as the RTX 3090 while the RTX 4080 could be receiving a spec bump.

The latest information was shared by Kopite7kimi who stated that while the NVIDIA GeForce RTX 4090 graphics card's specifications were the same as the ones he had posted earlier, the overall performance of the card has increased tremendously and now sits at over 2x versus the existing RTX 3090 behemoth. The said performance is purely rasterization so overall performance within games should vary but still, that's a big leap versus what the last generation had to offer. It also means that NVIDIA is putting that TDP-bump to good use since we are talking about a card that's expected to feature up to 450-500W TDP out of the box.
