Fresh rumours have filtered back from last week’s Game Developer and Graphics Technology Conferences in California about the make up of the next generation of AMD’s Navi graphics cards. While you’re off grabbing a bucket of salt to go with these rumours, why not pick up a nice reposado tequila and some wedges of lime too? This doesn’t have to be a painful experience for any of us.

A new video claims to have exclusive information about the upcoming AMD Navi GPUs, with the assertion that Team Radeon has already nailed down its plans for Navi 10 and subsequent Navi 20-based graphics cards. The former will launch this year, as expected, with the updated Navi 20 GPU design to follow in 2020.

That double act has been speculated on before, with the Navi 10 cards likely to fill out the mid-range of AMD’s graphics stack as a direct successor to Polaris, and the later Navi 20 cards being aimed more at the high end of the Nvidia competition. But what’s most interesting in the latest rumour mongering is the idea that the Navi 20 GPUs “will have some actual fundamental changes in architecture.”
