With the introduction today of the Intel Celeron D processor 351, Intel now has EM64T, or 64-bit memory addressability, available throughout its entire desktop and server processor lines.
With appropriate 64-bit supporting hardware and software, PCs based on an Intel processor supporting Intel EM64T can enable the use of extended virtual and physical memory. For example, on digital media applications 64-bit desktop computing enables faster performance with its ability to process more in main memory, also referred to as RAM, due to less data caching to and from the hard drive. Also, Intel processors supporting Intel EM64T provide headroom for processing high-definition video by enabling improvements in both speed and quality of workflow with its ability to handle large amounts of data.
"64-bit for the budget processor market"
Based on Intel's industry leading 90nm process technology, available in the LGA775 package, the Intel Celeron D processor 351 features a 256KB Level 2 cache, a 533 MHz system bus, a processor speed of 3.20 GHz, and support for the Execute Disable Bit.
Intel also announced that it is shipping the Intel Celeron D processors 346, 341, 336, 331 and 326 in the LGA775 package with support for Intel EM64T and the Execute Disable Bit. Intel communicated earlier this year it would be transitioning customers to the Intel Celeron D processor with Intel EM64T. By mid-2005, Intel had completed this transition.
Lastly, Intel announced the Intel Celeron D processor 350 today. The Intel Celeron D processor 350, available in the mPGA478 package, features a 256KB Level 2 cache, a 533 MHz system bus, supports Execute Disable Bit and has a processor speed of 3.20 GHz. This processor does not support Intel EM64T and is compatible with Intel 910 Express chipset-based platforms as well as Intel 845 and 865 chipset-based platforms.
The new Intel Celeron D processors 351 and 350, in addition to the new Intel Celeron D processors supporting Intel EM64T, are available now in prices that range from $73 to $127 for 1,000-unit quantities.
