X-bit Labs takes a look at some of the details of AMD's next-generation 45nm Bulldozer architecture:
At the most recent conference call with financial analysts AMD’s president and chief operating officer Dirk Meyer said that the next-generation micro-architecture and processors on its base code-named Bulldozer were in development with first samples due in 2009. What Mr. Meyer did not say is when the final central processing units (CPUs) were scheduled to arrive, a piece of information that both analysts and investors are curious to know.
“The Bulldozer core is in development in 45nm [process] technology and we will be sampling that in 2009,” Mr. Meyer told the audience.
Any transition to a new-generation micro-architecture and processor design is closely tied to transition to a new process technology. Chipmakers want to improve fabrication technology as much as possible before starting to make brand-new CPUs, therefore, manufacturing technology conversion happens before transition to new chip designs..
