Over at CES 2019, AMD demonstrated an eight-core Ryzen 3000 series processor and compared it with the Intel Core i9-9900K in Cinebench. In an interview with PC World, AMD CEO Lisa Su pretty much confirmed we're going to see Ryzen CPUs with 16 cores:
In the demonstration showed onstage—comparing a 3rd-generation eight-core, 16-thread Ryzen against an Intel Core i9-9900K, which lost to the Ryzen chip in the Cinebench benchmark—Su said that she wanted to establish a head-to-head comparison, using comparable core counts.
“Some people may have noticed on the package some extra room,” she said with a chuckle. “There is some extra room on that package and I think you might expect we will have more than eight cores.”
AMD's third-generation Ryzen CPUs are expected by Summer 2019.
