More on Bulldozer i did not originally quote that may shed light on more specs.
The intrigue remains about exact clock-speed of Bulldozer chips. Based on estimations, frequencies of such chips may be as high as 3.50GHz. What should be noted is that modern CPUs can include units that work at different clock-speeds and the highest one will hardly determine actual performance.
Four chips are not a large number and they will hardly be able to properly compete against rather huge Intel Core i7-series microprocessors, which includes quad-core and six-core offerings. But this - initial offering by AMD - may not be the "army" to attack Intel, but rather than a lineup to show what AMD is capable of: creation of a competitive high-end microprocessor. The second breed of Bulldozer-based chips due in Q4 is supposed to really improve AMD's positions on the market of expensive central processing units. By the end of the year AMD, based on a document seen by X-bit labs, expects approximately 10% of its CPUs to be FX-series in AM3+ form-factor.
AMD Orochi design is the company's next-generation processor for high-end desktop (Zambezi) and server (Valencia) markets. The chip will feature eight processing engines, but since it is based on Bulldozer micro-architecture, those cores will be packed into four modules. Every module which will have two independent integer cores (that will share fetch, decode and L2 functionality) with dedicated schedulers, one "Flex FP" floating point unit with two 128-bit FMAC pipes with one FP scheduler. The chip will have shared L3 cache, new dual-channel DDR3 memory controller and will use HyperTransport 3.1 bus. The Zambezi chips will use new AM3+ form-factor and will require brand new platforms.
