AMD's top CPU architect, Jim Keller, has left the company. According to Hexus, Keller is stepping down "to pursue other opportunities." AMD told the site that prior to his departure, Keller was responsible for "overseeing the teams defining the roadmaps for AMD's CPU cores, systems IP, and server and client SoCs," including the upcoming Zen CPU.
Keller rejoined AMD in 2012 after a long line of successes for other companies, including major contributions to Apple's A4 and A5 SoCs. His trophy case also includes work on AMD's own K7 and K8 processor architectures, the X86-64 specification, and the HyperTransport interconnect.
AMD told Hexus that Keller's departure won't affect the company's product or technology plans, and that it still expects to sample Zen processor cores in 2016, with the "first full year of revenue" to follow in 2017. Mark Papermaster, AMD's CTO, will take over Keller's responsibilities in the interim.
