AIDA64 release notes mention 16-core Ryzen CPUs and RX 500 cards
 

A few weeks after AMD launched its Ryzen 7 processors, rumors cropped up claiming that AMD had 12 and 16-core processors on the way. Seeing as Ryzen 7 proved to be a very capable performer when running heavily-threaded applications, it's perhaps unsurprising that AMD would take the multi-core design philosophy further still. AMD has confirmed the existence of many-cored Zen CPUs with its Naples platform, but the company hasn't made any announcements regarding similar consumer hardware. A new update to popular monitoring utility AIDA64 suggests we might be in for a surprise. Those many-core chips are mentioned by name, along with AMD's upcoming 500-series graphics cards.
