Dirk Mayer, President and Chief Operating Officer of AMD, has said to AMD's investors at its last week’s conference call that the new CPU architecture codenamed Bulldozer will debut in 45nm; and according to current agenda this is supposed to happen in 2009.

From what we know AMD will sample Bulldozer at late 2009, but the production parts are planned for 32nm. There is a possibility that AMD will launch Bulldozer in 45nm, but it will try to quickly move to 32nm.

AMD didn’t even start its 45nm production, and it has to heavily plan to go to 32nm. If you have one and a half fabs, their transitions tend to become real headache.

Currently, fab 36 produces all the Athlon, Phenom, Sempron and Turion CPUs you can buy, and Fab 38 is quickly coming to the rescue.
