RTX 4090 can provide fluid 4K performance that has never been feasible before.Deep Learning Super Sampling (DLSS) 3 offers an exceptionally remarkable performance boost, but even in games where it isn't yet supported, you still see an average frame rate improvement of over 70%.
The RTX 4090 is at the absolute top of the GPU market and costs $1,599; nevertheless, some PC cases may find it challenging to fit due to its large footprint. You'll need plenty of extra PCIe power connectors to power the RTX 4090 because it consumes 450 watts of power. This card can give a 4K experience unlike any other, though, assuming you can handle the cost, size, and power needs.Despite being almost 10 mm shorter than the RTX 3090, the additional inch in height gives it a more chunkier appearance.With the RTX 4090, Nvidia has also changed the power connector. It now employs the single 12-pin PCIe 5 standard, which offers a maximum total power output of 600 watts. The RTX 3090 Ti uses the same socket, and Nvidia includes a 12VHPWR converter cable in the box to allow you can attach four eight-pin PCIe power cables to it. Technically, only three eight-pin cables with a capacity of 150 watts each are required to be connected, which is half as many eight-pin cables as the RTX 3090 requires. Nvidia advises attaching the fourth eight-pin if you intend to overclock the graphics card because that provides 450 watts overall.
The Nvidia GeForce RTX 4090 is without a doubt the greatest graphics card ever created for the consumer market, but at $1,600 and with performance levels so high that the rest of your PC might not be able to keep up, this is truly only for people who have a very powerful computer to install it in. But if that describes you, this graphics card is unmatched.
