AMD's CEO, Dr. Lisa Su, has already confirmed that the company is working on high-end Navi at the CES 2020 show, so it does not come as a surprise that some new information has started to appear online. Surprisingly, a total of four new SKUs have been spotted in Eurasian Economic Commission (ECC) filings, including the Radeon RX 5800 XT, the RX 5900 XT, the RX 5950, and the RX 5950 XT.

Since we doubt that we are looking at two different Navi GPUs, it is possible that AMD will carve all new SKUs from the same "big Navi" GPU, and the RX 5900-series could go directly against Nvidia's own high-end, targetting both the RTX 2080 and even possibly the RTX 2080 Ti for 4K gaming.

The list, originally spotted by Komachi on Twitter, and neatly arranged by Videocardz.com, is similar to the one earlier seen by Sapphire. Unfortunately, there isn't a lot of information about the "big Navi GPU", so it is left to see if this one is based on the current RDNA or the next-gen RDNA2 architecture, which promises big performance and efficiency improvements.
