Intel to add "J" to processor models supporting the XD technology

Intel is going to add the letter "J" to the model numbers of its processors supporting XD technology. All Intel Pentium 4, Pentium M and Celeron D processors that support the Execute Disable Bit technology will contain the "J" letter in the product model number, e.g. Pentium 4 560J. This technology is a certain flag to determine wether instructions can be executed from the page. It may add extra security to PCs.

Chips featuring this security enhancement will be unveiled later this year. Besides this there will also follow some other new features. The Pentium 4 will receive 2MB of L2 memory and a 1066MHz FSB, the Celeron M will get 1MB L2 cache and the Pentium M wil be ramped up to a 533MHz FSB.

Also the Pentium 4 and maybe the Celeron D will gain AAC technology, which looks like AMD's Cool'n'Quiet. This technology adjusts performance depending on load in order to maintain low heat dissipation and quiet operation or PCs.
