Details emerged about the AMD "Renoir", the next-generation APU that will replace the 12nm "Picasso" APU. The new chip's graphics engine will still be based on the Vega architecture but there will be a new display engine to support the latest display standards:
Code-lines pointing toward "Vega" graphics with an updated display controller mention the new DCN 2.1, found in AMD's new "Navi 10" GPU. This controller supports resolutions of up to 8K, DSC 1.2a, and new resolutions of 4K up to 240 Hz and 8K 60 Hz over a single cable, along with 30 bits per pixel color. The multimedia engine is also suitably updated to VCN 2.1 standard, and provides hardware-accelerated decoding for some of the newer video formats, such as VP9 and H.265 at up to 90 fps at 4K, and 8K up to 24 fps, and H.264 up to 150 fps at 4K.
At this point, it's unknown whether Renoir will be a monolithic die or a multi-chip module consisting of a 7nm Zen 2 die plus an I/O controller die with the integrated graphics part. We do know that the processor's memory controller will get LPDDR4X memory support, at speeds of up to 4266MHz.
A possibly announcement date is CES in January 2020.
