I plan to buy RTX 2080 for machine learning task. But the price is very high! Now I use 1080Ti for my work which includes many image recognition tasks. After googling, I see that new RTX GPU will have Tensor cores in it, that are constructed specially for deep learning. So will I be able to perform image recognition at least 2x faster than now (as mentioned in the Nvidia presentation)? Or buying a new video card will not give me such a performance boost? Thanks for the help.
