Intel’s ‘Extreme’ Supports 64-Bit For Desktops

With chip advances from AMD and IBM on its tail, Intel burst into
the 64-bit desktop market today with a jazzed up version of its Pentium processor family.

After nearly a year of saying the desktop was not ready for
anything but 32-bit applications, the company said it is now shipping
five Pentium 4 chips with its Extended Memory 64 Technology (Intel
EM64T). The processors are enhanced with HT and EM64T technology
courtesy of Intel’s 925 and 915 Express chipset family.

The five new chips include P4 Extreme Edition (EE) running at 3.73
GHz and four P4 6xx sequence processors, all of which support Intel’s
Hyper-Threading (HT) Technology. Intel said it plans to ship EM64T on
versions of every newly introduced Intel desktop processor including
company’s Intel Celeron D processor lines later this year.

Intel has been steadfast in its claims that 64-bit
processing is best reserved for the high-end Itanium systems. But pressure
from AMD’s 64-bit Athlon family and the introduction of the Cell
, IBM’s joint project with Toshiba and Sony, changed that approach.

Intel said it now identifies the increasing number of customers that
are using their PCs for playing games or editing digital video and
images. And with an architecture that allows for 1 terabyte or higher
of physical memory addressing, Intel said it can help take advantage of
future software advances in high-definition video, audio and 3D

Rob Crooke, Intel general manager of
Marketing and Strategic Planning, said as software for the digital home and office matures and becomes more demanding, desktops with Intel EM64T are well-timed to take advantage of
emerging new usage models.

The new processors will support the upcoming Microsoft Windows XP
Professional x64 Edition operating system as well as next year’s
anticipated release of Microsoft’s next version of Windows, code-named Longhorn.

“We are working closely to deliver a robust 64-bit client platform
that will help customers realize powerful new 64-bit capabilities while
maintaining their investment in 32-bit applications,” Brad Goldberg,
general manager of the Windows Product Marketing Group at Microsoft,
in a statement.

As previous
ly reported
, Intel has been working hard to refresh its server and
desktop processors to line up with its 64-bit roadmap. In addition to
upgrading its Pentium and Celeron brands, Intel said it will ship a
multiprocessor code-named Potomac with 8MB L3 cache and its Twin Castle
chipset this spring. Intel is also preparing its 64-bit ambitions for
dual-core products for its Extreme Edition and Pentium processor-class
families during the second quarter of 2005.

The Pentium 4 Processor EE 3.73 GHz is the first Prescott-based EE
model that also features the Prescott 2M core and its 16K L1/2-MB L2
core architecture. This is a bit different than prior Extreme Edition
cores, which featured 512K of L2 cache along with 2-MB of L3. This is
LGA775 processor with the exact same physical specifications as the
Pentium 4 600 Series models, although it does run on the 1066 MHz bus.
Intel has turned the page on the Extreme Edition philosophy, and has
basically released a higher-clocked, higher bus speed Pentium 4 600
series under the EE brand.

The Intel Pentium 4 Processor 6xx sequence comes in speeds of up to
3.60 GHz, features an 800MHz system bus, a doubled L2 cache of 2MB, and
Enhanced Intel SpeedStep Technology (EIST). Windows XP Service Pack 2
supports the power-saving capability as well as Intel’s Execute Disable
Bit technology offers improved protection from certain types of

The new chips have created something of a logjam at the top of the
Pentium 4 Extreme Edition list, however. With its current Pentium 4
running at 3.46 GHz EE selling and performing to Intel’s expectations,
the new P4 EE chips are expected to stay atop the heap as there is
no 3.8 GHz equivalent.
