Im not sure if this is a dumb question or something, but i am curious, is the AMD Fx-6100 Black edition called as Bulldozer too?
Short story: The FX-6100 is an original Bulldozer-based chip.
Long story: There are usually two code names associated with any chip. The first is the code name for the CPU's architecture, which is usually shared with other, different CPUs sold at the same time by the same maker. For example, the Bulldozer first-generation modular architecture is used in the FX-6100 as well as the second generation of APUs and the second-generation C32/G34 Opteron server processors, despite the actual chips being significantly different. The second code name refers to the actual chip itself. The FX-6100 (as well as the FX-4100 series and FX-8100 series, since they are the same chip but with fewer or more cores enabled) are called "Orochi." The APUs with Bulldozer cores are called "Trinity." That way if you mention "Orochi," people will know that it has the same architecture as "Trinity" but is a different chip.
I agree with the big troll, if you are looking to buy a new 6-core AMD chip, I'd pick the FX-6300 over the FX-6100. The 6300 is named Vishera and based on the Piledriver architecture. Piledriver is a slightly tweaked Bulldozer which is slightly faster per clock, plus the Vishera chips clock a little higher.
