Jim Keller Reviews Moore’s Law, Computing and Considers AI Chips

Jim Keller is a legendary microprocessor engineer, who has worked at AMD, Apple, Tesla, and now Intel. He’s known for his work on the AMD K7, K8, K12 and Zen microarchitectures, Apple A4, A5 processors, and is a co-author of the specifications for the x86-64 instruction set and HyperTransport interconnect.

Jim Keller gives his perspective of the last 50 years of Moore’s Law and how it applies to AI Chips.

At about 26-28.5 minutes of the Jim Keller: Moore’s Law, Microprocessors, Abstractions, and First Principles | AI Podcast, Jim says that if you want to make real progress with computer architectures s then you need to rewrite every 3-5 years from scratch. Rewriting lets you make it less complex and faster.

Intel rewrites every 10 years. People tend to use recipes for solutions. However, those recipes only apply within certain constraints.

Moore’s law was double the transistors every two years. Jim Keller looks at 2X the performance every 2-3 years.

Moore’s law was always going to die in 10 years or some say is already dead. Jim knows there are thousands of innovations. Each has there own diminishing return curves.

Jim notes that transistors could reach 10 atoms by 10 atoms by 10 atoms while avoiding quantum effects. People are also working on harnessing quantum effects.

Jim sees 10-20 years of shrinking.

It is educational to listen to Jim’s talks and his interviews.
