Intel Desktop Processors Get 64-Bit Support

Intel

February 21, 2005 -

Intel Corporation announced the availability of five new processors for desktop computers. When coupled with the widely adopted Intel® 925/915 Express chipset family, the processors can help enable improved performance and more rapid response times for computing platforms.

Intel Corporation is now shipping the Intel® Pentium® 4 Processor Extreme Edition 3.73 GHz supporting Hyper-Threading (HT) Technology and four new processors in the Intel Pentium 4 Processor 6xx sequence supporting HT Technology.

All five of the new processors support 64-bit memory addressability through Intel® Extended Memory 64 Technology (Intel® EM64T). Intel plans to ship EM64T on versions of every newly introduced Intel desktop processor including the company's Intel® Celeron® D processor lines later this year.

The Intel Pentium 4 Processor 6xx sequence processors help enable new power-saving benefits to the desktop with Enhanced Intel SpeedStep® Technology (EIST). Similar to the technology used in Intel® CentrinoTM Mobile Technology, EIST can enable power-saving by reducing overall average processor power consumption.

The new processors will support the upcoming Microsoft* Windows® XP Professional x64 Edition operating system and will enable users to experience the benefits of 64-bit computing.

The Pentium 4 Processor Extreme Edition 3.73 GHz supporting HT Technology features a fast 1066 MHz system bus and 2MB of L2 cache that improves performance for such applications such as high-definition video and gaming that benefit from large amounts of data readily available to the processor.

The Intel Pentium 4 Processor 6xx sequence supporting HT Technology 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). This power-saving capability is supported by Windows XP Service Pack 2. Additionally, the larger L2 cache provides potential performance benefits while Execute Disable Bit technology offers improved protection from certain types of viruses when coupled with Windows XP Service Pack 2.
