AMD Bulldozer CPU Details, Images Leaked

AMD's upcoming multicore, high-end desktop processors, code-named Zambezi and based on its Bulldozer architecture, will be branded as AMD's FX series CPUs.

According to a report from Nordic Hardware, eight-core and four-core versions of AMD's Zambezi processors featuring AMD's TurboCore 2.0 technology are due in June.

AMD has confirmed that Zambezi will be listed under its FX line-up. The FX series processors are pictured with AMD's Black Edition moniker for high-end CPUs with unlocked multipliers in the leaked images. “'Zambezi' is a four-, six-, or eight-core 32-nm AM3+ socket desktop processor based on the 'Bulldozer' processor architecture for the enthusiast market," an AMD spokesperson on Monday told CRN. The 'Zambezi' CPU will carry the FX brand, and it’s planned for introduction in Q2 of this year."

AMD's Zambezi processors will target Intel's flagship 9000 series six-core desktop CPUs, although the six-core versions of Zambezi were not included in the leaked images. Instead, according to a report from X-bit Labs, AMD's FX-series Zambezi processors offers capabilities similar to Intel's high-end Sandy Bridge Core i7 processors.

Based on what appear to be leaked AMD documents, the report says AMD's Zambezi features more over-clocked cores and dual graphics, as well as OpenCL and GPU capabilities -- making the Bulldozer-based Zambezi more of an integrated graphics chip than a classic desktop CPU. According to the report, AMD expects that by year's end more than 10 percent of its desktop processors will be based on its Bulldozer reference design.

AMD's Bulldozer is a multi-threaded, high-performance x86 CPU that includes the 32-nm Zambezi chips with 4, 6 or 8 cores, according to AMD executives speaking at the company's Analyst Day in October. Bulldozer is also the reference architecture for two 32-nm server product lines, code-named Valencia, featuring 6 or 8 cores, and the higher-end Interlagos featuring 8, 12 or 16 cores. AMD said its Bulldozer architecture includes two integer units, along with one floating-point unit, and two threads on separate integer units rather than a single-core solution.
