According to a fresh report, Jum Keller, Chief Architect of Microprocessor Cores, has left AMD to pursue other opportunities.

According to a report from Hexus.net, a man that was responsible for the praised Athlon K7 architecture and was also behind the first native x86-64 bit architecture has left AMD. Jim Keller was also behind Apple's A4 and A5 SoCs before he rejoined AMD in 2012 to work on the upcoming Zen architecture.

According to a statement from AMD spokeperson, Keller was responsible for overseeing the teams defining roadmaps for AMD CPU cores, systems IP as well as server and client SoCs and while he was the key guy behind AMD's upcoming Zen architecture, AMD was keen to note that this will not impact its public product or technology roadmaps as the Zen is still on track for sampling in 2016.

This is definitely a big hit for AMD, especially since some rather important guys left the company back in January while ATI veteran Matt Skinner left the company earlier this month, leaving AMD rather short-handed.

Mark Papermaster, AMD's CTO, will be an acting leader for Keller's team as the company prepares to launch what will probably be the biggest update in the CPU roadmap, the Zen architecture.
