NVIDIA GeForce RTX 4090 with over 100 TFLOPS of power
NVIDIA next-gen flagship GPU is rumored to deliver over 2.5 times more raw compute power over RTX 3090 Ti.
While the rumors about AMD RDNA3 flagship processor indicate it will offer over 4 times more single-precision compute power over RDNA2, NVIDIA is supposedly doing a similar upgrade to its upcoming flagship. The AD102 GPU, based on Ada Lovelace architecture, is expected to deliver over 100 TFLOPS of power, which is 2.5 more than 40 TFLOPS offered by RTX 3090 Ti and 2.8 times more than RTX 3090. The FP32 (single-precision) power does not automatically guarantee better gaming performance, though.
To be honest, I don't have much information about AMD. Maybe Lisa and Jensen's competition will give us a 100TFLOPS gaming war in a few months.

Both Greymon55 and Kopite7kimi agree that the TFLOPS war will only be a part of the battle for the fastest desktop graphics. There is more at play, such as raytracing acceleration, supported super-resolution tech and other features that may tip the scales in favor of any architecture.
I can only say that the two products have improved a lot compared to their predecessors, but if you want to ask me directly which one is better, I'm sorry I can't answer, because no one knows the specific improvement by percentage.

To achieve 100 TFLOPS of power, the AD102 GPU with 18432 CUDA cores would have to be clocked at 2.7 GHz, but it’s almost certain that RTX 4090 will ship with a partially disabled GPU. Therefore, the clock speed will automatically be higher. According to Greymon55, next-gen flagship cards might ship with very similar clock speeds, which in the case of AMD Navi 31 GPU means 3.0 GHz and that’s assuming full GPU is used.
It is true that we know a lot about next-gen GPUs already, some rumors have been around for months. But this does not mean that we know everything yet. The FP32 CUDA/Stream Processor count can still change. What all leakers appear to agree with is that next-gen GPUs will require a lot of power.
