An AMD representative has recently commented on the reasons behind the delay of the company's future Zambezi FX processors, stating that this is only a strategical decision meant to favor the upcoming Llano APUs. “The order in which we bring products to market is purely strategic,” said Guido Lohmann, AMD PR Manager Northern Europe when asked about the reasons behind the Bulldozer delay by Planet3DNow. “The very gratifying success of the C-and E-series APUs has led to the decision to go ahead first in the desktop area with an APU, and then to follow with the Bulldozer processors,” concluded the company's rep. At this year's Computex fair, AMD has officially announced that the first Zambezi FX processors, based on the Bulldozer architecture, aren't expected to arrive until later this summer (August or September). Before the news was made official, various reports suggested that AMD is having trouble with the performance of its Bulldozer architecture, as the first chip revisions functioned at lower than expected frequencies. In order to fix these speed issues, AMD reportedly plans to build a new Bulldozer stepping, called B2, which should make the chips competitive with Intel's offerings. At the 2011 Computex, AMD was expected to launch four FX-series processors based on the Bulldozer architecture, two featuring eight processing cores while the other two packed six and respectively four CPU cores. The clock speeds of the two high-end, eight-core, parts were supposed to be set at more than 3.5GHz, but it seems like the B1 and B0 revisions that AMD has right now stop at about 2.5GHz. All four chips were targeting the high-end desktop space and were supposed to feature an unlocked multiplier, support for AMD's Turbo Core 2.0 technology and an integrated dual-channel DDR3-1866MHz controller.
