According to the findings of a Chiphell user called "wjm47196", AMD is supposedly going to host an event at CES 2020 to showcase its next generation of Radeon graphics cards. Having seen huge success with its first-generation "RDNA" GPUs, AMD is expected to showcase improved lineup utilizing new and improved RDNA 2 graphics card architecture.

Judging by the previous information, second generation of RDNA graphics cards will get much-needed features like ray tracing, to remain competitive with existing offers from NVIDIA and soon Intel. Supposed to be built using the 7 nm+ manufacturing process, the new GPU architecture will get around 10-15% performance improvement due to the new manufacturing process alone, with possibly higher numbers if there are changes to the GPU core.
 
If this is true then AMD will be able to release next year's GPU ahead of NVIDIA who is (via the rumor mill) to release their next gen GPU in the 1st half of 2020.

It's cool that AMD is bringing their 2nd gen gpu's to market, I'm no AMD fan, however, hopefully they can mustered more than 10-15-20% performance increase. I don't think 
 
will compete with 2080ti that is already over a year old, thus no reason for Nvidia to be in rush to bring out the big gun.
