A bit of a warning, three so-called "official" AMD slides are making rounds on the web showing what the performance of the "RX 6900 XT" would look like including full specs, pricing, and a photo, of course, they are completely fake.
According to these slides, the RX 6900 XT (With the old Radeon logo, liquid cooling shopped in on a stock vega card) would have 80 Computing Units, 22.73 TFLOPs, 14GB of GDDR6 memory with a bandwidth of 1008GB/s, boost frequency of 2220MHz, Game Clock of 2055MHz, and base frequency of 1890MHz. All this for $999.
Everything you see there is bogus, incl the footer of the slide says that the NDA ends on September 30. I love the last slide though, where it states performance with "RXRT" ON. Guys, we're not going to see official slides any time soon. I see a number of Youtube channels making clickbait titles like "AMD "Big Navi" RX 6900XT 14GB Leak" already. Don't believe everything you see on the internet.
