>AMD FX is a series of high-end AMD microprocessors for personal computers which debuted in 2011

Ha, well that's wrong. This is the first time I find a mistake or more accurately, a contradiction in Wikipedia.

AMD's first FX CPU (the FX-51) came out in 2003 as a premium Athlon 64 that was an expensive power hungry beast, which is the one I assume the GP was talking about. Here, also from Wikipedia:

"The Athlon 64 FX is positioned as a hardware enthusiast product, marketed by AMD especially toward gamers. Unlike the standard Athlon 64, all of the Athlon 64 FX processors have their multipliers completely unlocked."

It's not contradictory. The "FX" you're talking about is used as "Athlon FX"[1], whereas the "FX" in the article is "AMD FX"[2]. The branding might be a bit confusing, but the article isn't wrong.
