RE: Power6 on System i

["Pete Massiello" <pmassiello@xxxxxxxxxxxxxxxx>]

You have to realize that when people talk about a 515, it really doesn't
have 3800 CPW.  CPW is measured with max memory and max disk, but a 515 is
constrained by only 16GB of memory, and all the disk must reside in the
CEC, no HSL connections, nor external disk.  Therefore, you would never be
able to get 3800 out of a 515.

Its a fantastic box, and unbelievable when you look at price vs
performance, but you won't get 3800 CPW from the box.  Now, when you talk
about power 6, you are going to have much higher clock speeds on the CPU,
which will make the CPU intensive jobs run better, but remember that most
i5s tend to be constrained by I/O.  So, as you increase clock speed, you
must also increase the speed of memory, the speed of the bus, and the
speed of I/O to really get the best performance.

JMHO
