The FX-series processors are built from Bulldozer-blocks, all of which comes with two "cores". Depending on the point of view the FX-8150 can be considered either an 8-core processor, or a 4 core processor with advanced hyper threading. According to AMD sharing some of the resources instead of using a "true 8-core design" helps balance the cost, performance and scaling.

The FX-series processors come with two levels of turbo: one that ups the clock speed on all cores, and one that can speed up half of the cores, while dropping the rest to power saving CC6-state. Depending on the model all cores can go up 100-300 MHz, and in Max Turbo-mode the gains are 200-900 MHz. This should be particularly helpful in programs that only load a few cores, such as games.

With all the threading and Turbo-modes there's a problem with the scheduler of Windows 7 that doesn't really understand the idea of Bulldozer-cores and uses the FX-8150 as a "real" eight-core processor. This leads to threads ending up in the wrong Bulldozer-units, which again means the Turbo-mode can't activate. In Windows 8 this problem should be fixed, and depending on the program this should lead to noticeable performance gains.
