As VideoCardz reports, this is not the first time that these names pop up. But it's possible that these will not be the final product names of what we know as AMD's "Big Navi" GPU. Guess we'll find out later this year.
The interesting part is that their cards usually launch with weeks or even months of delay. That said, it is surprising to see yet unreleased Radeon graphics cards such as RX 5950XT, RX 5900 or RX 5800XT showing up this early thanks to AFOX. The company does not even have any RX 5000 model listed on their website.
However, this is not the first time we are hearing about these SKUs. Back in June 2019, Sapphire submitted an almost identical list to EEC. That was even before the Radeon RX 5700 series launched. That gave a hope that AMD may actually launch the full series in 2019 but in the end, that was not the story.
