Biography

Jim Keller is a microprocessor engineer best known for his work at AMD and Apple. He was the lead architect of the AMD K8 microarchitecture (including the original Athlon 64) and was involved in designing the Athlon (K7) and Apple A4/A5 processors. He was also the coauthor of the specifications for the x86-64 instruction set and HyperTransport interconnect. From 2012 to 2015, he returned to AMD to work on the AMD K12 and Zen microarchitectures.

Education

He holds a B.S. in Electrical Engineering from Pennsylvania State University.

Career

Jim Keller worked at DEC until 1998, where he was involved in designing the Alpha 21164 and 21264 processors. In 1998 he moved to AMD, where he worked to launch the AMD Athlon (K7) processor and was the lead architect of the AMD K8 microarchitecture, which also included designing the x86-64 instruction set and HyperTransport interconnect mainly used for multiprocessor communications.

In 1999, he left AMD to work at SiByte to design MIPS-based processors for 1 Gbit/s network interfaces and other devices. In November 2000, SiByte was acquired by Broadcom, where he continued as chief architect until 2004.

In 2004 he moved to serve as the Vice President of Engineering at P.A. Semi, a company specializing in low-power mobile processors. In early 2008 Keller moved to Apple. P.A. Semi was acquired by Apple shortly afterwards, reuniting Keller with his prior team from P.A. Semi. The new team worked to design the Apple A4 and A5 system-on-a-chip mobile processors. These processors were used in several Apple products, including iPhone 4, 4S, iPad and iPad 2.

In August 2012, Jim Keller returned to AMD, where his primary task was to lead development of new generation of x86-64 and ARM microarchitectures called Zen and K12. After years of being unable to compete with Intel in the high-end CPU market, the new generation of Zen processors is hoped to restore AMD's position in the high-end x86-64 processor market. On September 18, 2015, Keller departed from AMD to pursue other opportunities, ending his three-year employment at AMD.

In January 2016, Keller joined Tesla, Inc. as Vice President of Autopilot Hardware Engineering.

In April 2018, Keller joined Intel.

Personal life

Jim Keller is married to Bonnie Peterson, sister of clinical psychologist Jordan Peterson.
