An Intel-based Cray supercomputer will probably look similar...

"Intel-based Cray" - that is just sooooo wrong...

"Intel-based Cray" - that is just sooooo wrong

Not any more. It's inevitable. The constant pressure of Moore's Law, doubling the transistor count on a die every two years, for several decades now, without signs of letup, is putting what I used to think of as multiple (today, four, but double that every two years) high end CPUs on a single package.

Once you're inside that package, on that single chip, then you're in the world of Intel and AMD and few others. System makers such as Cray no longer build their CPUs. They buy them, several to a single die package.

This is just the next step in an unstoppable evolution that has been ongoing in the computer business since World War II.
