Maximum PC: AMD has a knack for reaching milestones before the competition. The Sunnyvale chip designer is generally credited as being the first to reach 1GHz with its Athlon chip (a claim Intel disputes, by the way, as it was also shipping 1GHz Pentium III parts), and just like it's the year 2000 all over again, AMD is again touting a speed victory by unveiling the world's first 5GHz processor for consumers.
KitGuru: Today we are looking at the new AMD FX9590, clocked at an eye popping 5ghz. The FX9590 is shipped with a base clock of 4.7ghz and a maximum turbo speed of 5.0ghz – the all important figure which has already started a plethora of news stories across the net. AMD wanted to be the first out the door with a 5ghz processor and they achieved it. The question we ask today- ‘Ok – 5ghz, but at what cost?’.
I think they are the only ones running in this race anymore.
