AMD has issued new Linux patches that add support for two upcoming APUs. The first one is Dali, a chip that's expected to target the value/mobile segment in 2020. Next there's Renoir, this APU is expected to offer a higher performance level.
Phoronix went over the details and says the patches suggest that Dali is a newer revision of the Picasso APU, while Renoir APU features new display and video blocks:
While we're still waiting on more Dali patches to come out, at this stage it's looking to be a near facsimile to current AMD Vega-based Picasso APUs and not featuring any new display or video blocks like we're seeing with the beefier Vega-based Renoir.
