Tech report reports that AMD released a graphic novel titled “The Legend of FX” last week in a rather strange effort to build some hype for the brand’s revival later this year. The Legend of FX takes some jabs at Intel while touting AMD’s superior graphics and improved performance, but it’s the recently posted cinematic trailer promoting the novel itself that brings a juicy tidbit: hidden at 0:15 is the date “September 19” which some have taken as a hint for when FX will see the light of day.

WCCFTech claims to have confirmed a September launch date with Taiwanese motherboard manufacturers and says four processors will make the initial FX lineup — the FX-8150, FX-8100, FX-6100 and FX-4100.

The range-topping FX-8150 packs eight cores clocked at 3.6 GHz (or up to 4.2GHz in Turbo mode) and has a TDP of 125W, while the FX-8100 drops frequencies to 2.8-3.7GHz and the power rating to 95W. The six-core FX-6100 and quad-core FX-4100 will also have a TDP of 95W and feature base/Turbo clocks of 3.3/3.9 GHz and 3.6/3.8 GHz, respectively.

The chips are all based on GlobalFoundries’ 32nm process technology, come in an AM3+ package, and have a built-in dual-channel DDR3-1866 memory controller. They also feature 1MB of L2 cache per core, 8MB of shared L3 cache, and unlocked multipliers. A previous leak covered here mentioned four additional FX chips and a possible delay into Q4 of 2011, so until we get an official announcement from AMD we won’t know for sure.
