[news] Intel Prescott Already Has 64-bit Extensions *IMPORTANTE*

Apparently, the extensions may be a part of the well-known Yamhill project and will not be compatible with AMD's 64-bit extensions

AN ARTICLE on the Akiba PC Watch site yesterday suggests
that Intel may be in such trouble over its next
generation Prescott microprocessor that it could be
pushed back to the second quarter of next year.
Intel's line in the last few weeks has been that it will
begin revenue shipments to some PC manufacturers this
quarter, with roadmaps seen by the INQ showing it would
ship in late January, February.

But, according to this Japanese article on Akiba Price
Watch, Intel continues to have big problems with the
Prescott design.

The article says that Prescott - which was plagued by
heat problems as we reported in spring this year, is also
suffering from bus problems and difficulties related to
the 875 and 865 chipsets. Many motherboard makers have
released Pentium 4 boards which have the same socket for
478 pins that initial Prescotts will use, so for
customers hoping to upgrade, this is a serious problem.

The Japanese article says systems won't work with 800MHz
front side buses, while Intel is frantically attempting
to create fresh packaging and a further stepping - C1 -
for the chip.

But qualification samples, the article continues, aren't
likely to go out the door until December. That means that
if Intel makes its own February deadline, volume is
unlikely to appear until the second quarter of next year.
And Intel's most recent roadmaps suggested that it would
start using the LGA775 design for Prescott in Q2 as well,
which is when its "Grantsdale" chipsets are supposed to
appear.

If the reports are true, the delay might mean not only a
boost for AMD with its Athlon 64 family, but also goes
some way towards explaining why Xeon MP chips at speeds
of 3.2GHz and 3.4GHz and with large caches, are in the
pipeline.

If that's so, Intel would appear to be cannibalising its
own products in a bid to compete with AMD.

Meanwhile, unconfirmed reports reach the INQUIRER that
Intel might shove its Pentium 4 EE forward to the 4th of
November - so called "mischief" night in some parts of
the United Kingdom. µ

We managed to find out some more information about Intel

Prescott processor than the Santa Clara, California-based
company wants everybody to know. According to a source
whishing to remain anonymous, Intel's next-generation
NetBurst CPU code-named Prescott does have 64-bit
extensions. But Intel does not desire to enable them
because of some reasons, the source added. Apparently,
the extensions may be a part of the well-known Yamhill
project and will not be compatible with AMD's 64-bit
extensions available now in AMD Opteron and Athlon 64
processors.

Intel's top managers have been considering the

enablement of the 64-bit extensions in Prescott and Tejas
processors for some time now, but no final decisions have
been made. What we know for sure is that Intel is not
likely to turn on additional functionality of the
Prescott processor until 2005, probably when AMD's 64-bit
processors become more or less wide-spread on the market
and may affect Intel's sales. Intel has been saying that
its 32-bit and 64-bit processors will co-exist totally
independently in different market segments and has never
confirmed plans to implement 64-bit extensions into its
IA32 chips. Intel Itanium processors, on the other hand,
can emulate conventional x86, but not really fast
