"Bulldozer" Microprocessors. Advanced Micro Devices on Wednesday officially confirmed the postponement of its highly-anticipated FX-series central processing units. The code-named Zambezi chips based on the Bulldozer micro-architecture will be 60 to 90 days late and will emerge in August or September, according to the company.
During the company's press conference dedicated to the launch of AMD 9-series core-logic sets, AMD announced that its long-awaited FX-series microprocessors will be available within the next 60 to 90 days from now, which points to August or September. Mainboards based on the new AMD 9-series chipsets with AM3+ socket will support both existing high-performance multi-core Phenom II microprocessors as well as AMD FX-series chips with up to eight cores.
Early this week it turned out that AMD had advised its partners that its next-generation high-performance desktop chips would only be launched in September. Apparently, the currently available B0 and B1 stepping Zambezi/Bulldozer processors can function at around 2.50GHz/3.50GHz (nominal/turbo) clock-speeds and at such frequencies they cannot deliver performance AMD considers competitive, a person with knowledge of the situation said on Monday.
As a consequence, AMD needs to tune the design of the processor and create B2 stepping of the chip with better clock-speed potential amid similar thermal design power (TDP), which will take several months to complete.



Wait until all thing is done.. thanks for your attention.
