Do the math.. then RECALCULATE

<Should those sockets be filled with Intel's quad-core Xeon chip, then you're talking bout 80 cores per chassis and 560 cores per standard 42U rack.>>

NOBODY can fill a 42U rack with ANY kind of blades without some serious refrigeration orthodontia ...

Arithmetic is great, but the laws of thermodynamics is greater. density doesn't mean SQUAT if ya can't cool it, and bro' NOBODY can cool that much CPU in that dense a space, even with ICE WATER forced through the rack.

Theory is swell, reality sucks .....
