AMD's future plan seem to be great at inducing headaches as the company is trying to make sense of two chip revisions and quad- and triple-core processors. The road to making the TLB bug-free B3 stepping seems to be on almost at an end but the migration towards the new parts is and will be slow. The Phenom 9550 and 9650 which will replace the 9500 and 9600s respectively will be released in Q2 but the 2.6 GHz 9900 model, which has already been showcased in its B2 form, apparently will not.

The B3 Phenom 9900 is being replaced by the 9950 and although this should be nothing more than a name change so as to emphasis (9X50 meaning B3) the fact that the CPU is a TLB-cured quad-core, the 9950 is slated to start shipping in Q3. The Phenom 9900 was known to be a Q2 part but somehow we're not really shocked with the delay.
