This is why I keep suggesting that AMD has an easy path to increasing volume greatly. They already have a great design in Renoir/Lucienne. Why not make a "half" Lucienne? One 4 core CCX, 4CUs in the IGPU, 8 total lanes of PCIe enabled (4 for SSD, 4 for other). It'll be roughly half the size of existing Renoir/Lucienne and grant about twice as many chips per wafer. SKUs, 4/8+4, 4/4+4, 2/4+3, 2/2+2. That would clean up in mobile and OEM.
Yields should be good enough for Renoir/Lucienne at this point that selective binning for quad core processors is no longer needed and scavenging can supply the long PRO SKUs. The main question is, us the return worth the investment?
