Interesting,
Them guys gave a presentation over here some time ago.
The numbers they "quoted" for a HP Superdome was 80 MIPS per engine, with
up to 64 engines.
Are they now stating that using Itaniums can generate 350 MIPS per engine,
that means that upgrading from the original HP Superdome, to an Itanium
based system, is a 400% improvement.
(gossip about unqualifiable numbers :-D )
It means Itanium is 4.3 times faster than AMD. I doubt it.
BTW: IMHO comparison of CPUs is senseless when we talk about *computer speed*.
What about I/O ?
I saw Hercules on PC, almost 40MIPS, but TSO logon time was over 5 minutes.
Every I/O operation was slooow.
IMHO the strengths of mainframe are:
a) I/O
b) OS
