Intel/AMD Battle Rages On

An anonymous reader writes "The battle between Intel and AMD has broken out of the cleanroom and literally into public view with AMD's public display CPU speed challenge to competitor Intel. Should the competition take place, the infamous chip makers will battle their best 2-way and 4-way configurations for the latest title as speed king." From the article: "AMD's proposed dual-core duel would be a live, public performance evaluation between server platforms based on the dual-core Opteron 800 Series or 200 Series processors and the corresponding Intel product. Should Intel accept AMD's challenge, the duel would take place at a public venue to be announced in the coming weeks, with testing conducted by a neutral, third-party testing lab. "

    I can be as unbiased as it gets.
    Especially if both companies give me an equal-valued check.
    Send me sealed machines, externally similar cases, preferently ship both together (one company's courier meets the other in UPS's office, they wrap the computers in unmarked boxes). Make only one distinctive mark with a Sharpie pen in one of the cases, give me a week and I'll give you the result, posted in a website:
    "The marked machine performed ..."
    "I put the unmarked machine in such and such situation and ..."
    "Final result and conclusion: the unmarked machine wins."
    Someone else can open the sealed envelop and tell the world who is who. I don't care.
    (I get to keep both computers.)
