Ah, now I see!

I never could understand why IBM designed their blades so you couldn't actually run a full chassis at 100% as there wasn't enough power in the chassis, but now I see it was because they wanted to save power in the datacenter for these 4.7GHz Superovens! Or maybe we should name them Supernovas.

So, Sun will have chips that can real fast but only with massively multi-threaded apps, and IBM will have massively hot boxes that will run fast if you rewrite the code (and base your datacenter in the Antartic), and HP will have boxes that will run four different OSes so you can pick and choose your OS/app stack for best performance and change it at will.... My money's still on the Itaniums.
