Well the clockspeed in hardware is a pretty important thing. But if you go
analyze them you'll see that the thing is pretty good in floating point, but
sucks ass for integers.

The velocity engine never impressed of course at the g4. The raw number of
gflops it delivers is more interesting than such features and that is pretty ok.

Many computerchess people seem to be happy with the for computerchess inferior
P4s when compared to the cheaper and faster K7s. If that's the case then i do
not see that when the G5 is like tripling at least the performance of the
outdated G4s, why the mac diehards would be unhappy with the G5.

I know very well the average Mac User. They have learned with big effort to use
OS/9. Usually at dual Mac Servers they also install OS/9, though OS/x by default
is running at it.

They have major problems to learn OS/X, where it is trivial for us to use.

Put such a user behind windows with the SAME software and it still will go
wrong!

I'm not joking here that is the sad truth of the average mac user.

So if they get a gun now that can do 64 bits floating point very quickly, then
it's a great thing to have for them.

Whether Opteron is quite a bit faster and Itanium too, that's simply not
interesting (P4 isn't 64 bits so not even *close* to the same performance).

That a dual opteron server is cheaper than a G5 server and that itanic works
well on paper, is simply not relevant.

They can use that G5 therefore it'll be a big succes.
