AMD Now Working New B3 Revision Bulldozer

After many are left disappointed by the performance of AMD's FX-series processors based on the Bulldozer architecture, the chip maker is now working on new revisions of its CPUs that will bring the B3 stepping.
This information is found by Hardcore-AMD Hardware in a public document entitled "BIOS and Kernel Developer's Guide (BKDG) for AMD Family 15h 00h-0Fh Processor Model". The document includes a table that states the current stepping of AMD Bulldozer, but also a new revision of the architecture is referred to as B3.  

Unfortunately, the report did not detail the changes that AMD wants to bring to the chip with the introduction of this new step, but users should expect the usual tweaks that give slightly better performance and better energy efficiency. 

This is not the first time that AMD has a problem with a new processor architecture. Shortly after the company launched its first quad-core CPUs from the Phenom line, has been found that the chip disabled (translation lookaside buffer) issued by BIS at least 10% performance penalty. Design issues required to build stepped AMD new chip, known as B3, which arrived about four months after the initial release of the Phenom.

AMD launched its FX-series processors based on the architecture Bulldozer first week, on October 12, but although eagerly awaited by many PC enthusiasts the performance of the chip have been disappointed.
In most tests run by the reviewer, flagship of the lineup CPU AMD FX-Series, FX-8150, lagging behind Intel's Core i5-2500K, some tests even showed it coming in the back of the last-gen processor Phenom II X6 1100T.
Now, there is information regarding the release date of the B3 stepping is available, but considering the current position in the market AMD CPU makes sense for this revision to be placed on top of the list of corporate priorities.
