AMD Bulldozer

Product lines

The product lines built on Bulldozer, with the market segment the vendor sells each in and the sockets or soldered (BGA) packages its processors come in. Each socket links to the vendor page that states it.

Why not x86-64-v3?

Bulldozer lacks AVX2, BMI1, BMI2, F16C, FMA and MOVBE, all of which x86-64-v3 requires.

Feature checklist

Features required by each x86-64 level and whether Bulldozer has them. OSFXSR and OSXSAVE are set by the operating system; the table checks the hardware features they depend on.
