the problem of the xeon 2.8 Ghz is that the P4 2.8Ghz is not
even getting delivered by the shops here, despite that it was
ordered for example by Jan Louwman. Not to mention the Xeon.

Could be months before it is here in Xeon form. Right now
fastest Xeon for example www.alternate.nl delivers is:

Xeon 2.0 Ghz

whereas the 2.8 Ghz P4 is on the list as 'deliverable'
and the 3.0 Ghz P4 is on the list as 'coming soon'.

But that 'deliverable' of the 2.8Ghz P4 we must take
with a graint of salt. It's ordered before dutch open computerchess champs
even by Jan Louwman (weeks before it). So that was like end of september.
It's november now.

As a replacement he got a bunch of 2.53Ghz P4s delivered until they could
deliver 2.8 Ghz and they didn't yet. So i expect those 2.8Ghz to arrive
soon.

But that's P4s. That's not even near what Xeons do.

www.comptechworld.nl has the Xeon 2.4Ghz on their list but doesn't want to
do statements on when they want to deliver them, especially considering they
get delivered for only 367 euro, that'll take a while i bet. Knowing
how fast these cpu's have gone down in price, it will be no surprise to
you that *no one* here has those CPUs in stock. They need to get from
abroad always.

Same story is also true for latest AMD cpu's, but their jumps are smaller.

That P4 is clocked to 3.0 Ghz already, quite a big difference from the
2.53Ghz which can get delivered now.

The Xeon is officially at 2.8Ghz now but all what you could get within a
few weeks is a 2.4Ghz.

And that is perhaps *not* the northwood yet. I do not know.

It's the more recent core that's a lot faster than the old P4 core.

Johan de Gelas is a very good tester. His results, without posting it,
he repeats times and again in a very objective way. I was amazed by his
accurate testing, this was around july 2001.

The article took a month to place or so. In july 2001, the 1.2Ghz MP K7s
from which i still have 2 processors here, they blew away *every* PC
on the planet.

The fastest machine before that was a quad Xeon 700, but that K7 core is
*so much better*, at least 20% than the P3-Xeon, that the compare was
not very accurate even.

The later introduced 933Mhz Xeons were called back to the factory because of
bugs in them.

So *nothing* could beat it at all.

The later improved P4s (i guess that's the later northwoods) are improved
at more points than just a bigger L2 cache, as seemingly initially was
reported. A major difference obviously is that they have DDR ram nowadays.

RDRAM at least for computerchess is a big failure IMHO.

Yet the extra speed the northwood delivers i cannot explain just by DDR ram.

I bet intel doesn't want to speak about it much it has to be something
small that's internally changed which has a big impact (and probably was
a small change but very difficult to manage).
