Hardware fix for the infamous "TLB bug" was implemented in core revision B3 of Phenom and Third-Generation Opteron microprocessors. These CPUs no longer required the temporary fix, and, as a result, had better performance than B2-revision processors. Actual performance gain in newer processor was very dependent on application type. The gain could be unnoticeable in small, CPU-bound applications, or it could be as high as 60% - 70% in memory-intensive applications, such as WinRAR. On average, B3-revision CPUs had 5% - 10% higher performance. To reflect their better performance, AMD added 50 to their model numbers. For instance, this 2.2 GHz Phenom X4 processor with B3 core stepping has model number 9550, while older B2 stepping Phenom X4 CPU with the same internal clock frequency and CPU features has model number 9500.

I have received a Phenom from a Canadian supplier HD9550WCJ4BGH and it is definitely in a box with a heatsink and everything. UPC on the box is 730143265027

Other writings:

Response: Please see if the box has OPN HD9550WCGHBOX on it. The CPU itself is always marked as HD9550WCJ4BGH, even if it's shipped in a b

All of the HD9550WCJ4BGH series chips I have seen have been OEM/No HSF/Box. Also have seen and tested boxed versions we put in new builds for customers and none of them were HD9550WCJ4BGH. I know AMD has at least a couple locations (plants) where they manufacture chips. Not even sure if those 2 versions are manufactured in the same location. I wonder is if there was a mixup or boxed version of the HD9550WCJ4BGH then that would be about the only way it would have happened. Not that it matters, same chip, same setup, freq, voltage, etc.. The one I posted the CPU-Z up on here is OEM version. I am running one in my machine at home :)
