AMD Bulldozer FX 'Zambezi' chips detailed

The first firm details of AMD's FX-series 'Zambezi' processors, based around the company's Bulldozer architecture, have leaked out ahead of an official launch later this year.

According to an internal AMD document leaked to the guys over at X-bit Labs, the FX-series will initially be comprised of four chips: the four-core FX-4110, the six-core FX-6110, and the eight-core FX-8110 and FX-8130P. All four, the document suggests, will be available as a 'Black Edition' - meaning they will feature an unlocked core multiplier for easier overclocking.

Each model will include 'up to' 8MB of L3 cache memory, along with 1MB of L2 cache per core - so 4MB, 6MB, or 8MB depending on the model. Most feature a 95W thermal design profile, with the exception of the flagship FX-8130P model which boosts the power draw to an impressive 125W.

All four processors are designed to operate with AM3+ motherboards, and are built on a 32nm silicon-on-insulator processor by AMD fabrication spin-off GlobalFoundries. Each also includes AMD's Turbo Core technology, which allows some cores to be overclocked for better single-threaded performance as and when required.

Sadly, there's one vital piece of information missing from AMD's internal documentation: clock speeds. While it's known that the memory controller integrated into the chip will be running at 1,866MHz, the actual clock speed of each processor is currently unknown - and AMD's keeping quiet until the official launch.

As if official-seeming specs weren't enough, the guys over at Nordic Hardware have got their hands on what they claim is the finished box art for each model. As the first chips AMD has launched in years to not feature a branding such as Athlon or Phenom, the company appears to be opting for a striking style to make the boxes stand out on a crowded retail shelf.

The leaked box art - which has yet to be confirmed as genuine by AMD - confirms the presence of four and eight-core models, along with the Black Edition overclocking functionality, but box art for the alleged six-core model has yet to be seen.

With Intel maintaining its lead on AMD with the Sandy Bridge processor family - despite some hiccoughs along the way - it remains to be seen if the FX series helps AMD get back in the game.
