AMD is also working on a new 64-bit x86 Core

Jim Keller joined Mark Papermaster on stage at AMD's Core Innovation Update press conference and added a few more details to AMD's K12 announcement. Keller stressed AMD's expertise in building high frequency cores, as well as marrying the strengths of AMD's big cores with those of its low power cores. The resulting K12 core is a 64-bit ARM design, but Jim Keller also revealed that his team is working on a corresponding 64-bit x86 core.
The x86 counterpart doesn't have a publicly known name at this point, but it is a new design built from the ground up.

AMD has been laying off their design team in Austin in large numbers so I am curious on how they plan on developing two new ISA designs. There is sure to be some re-use in the SoC but the most complex portion is the CPU. ARM and x86 ISAs are very different so it is not as easy as changing the decoder. There are very different instructions for load/store, security so I can't see much re-use in the CPU. Maybe the adders, multipliers and high level micro-architecture widgets but it is two separate efforts. With a reduced team. Jim Keller is no superman - far from it in my opinion so given their execution track record, they are setting themselves up for a huge challenge here.Gizmosis350k - Wednesday, June 25, 2014 - link
Jim Keller is the greatest don't talk down the guy. When AMD scales up his designs to the PC space great things will happen, Don't come in here talking trash just because you typed on a keyboard plugged into a box that says iNtel Inside. Be level headed and see that AMD is putting out the real trash, folks like you, and getting people who've been in the business have KNOWLEDGE and EXPERIENCE about engineering the NEXT BIG THING in x86 and ARM.
