Power6 Chips, Gimme Speed!

february 7, 2006

You have to wonder why Apple truly moved away from the Power6 chips over to Intel chips.  And have to wonder hard when IBM announces something like this:

Power6 is expected to run between 4 and 5 gigahertz. Intel's Itanium 2 server processor today tops out at 1.66 gigahertz. The Pentium 4 for desktops currently reaches speeds of 3.8 gigahertz.
All the while, the chips will be cool (temperature-wise) and power efficient.  So, why did Apple want to move to Intel?  Wasn't their  big thing that Power6 chips did not deliver performance per watt of power?   Does n't this really go to show that there is much more performance per watt in Power6 chips?
