9. The New Models Of The Pentium M
Intel is presenting seven new Pentium M and two Celeron M CPUs. The new Pentium M CPUs with the faster 533MHZ FSB are quite easy to spot due to their processor numbers, which are divisible by ten.
Intel specifies the thermal design power (TDP) of the new Pentium M models at 27 watts. According to Intel, however, this does not mean that the power loss of the models with a faster FSB is 30% higher than for products with an FSB speed of 400MHZ. After all, according to Intel, the TDP constitutes merely a theoretical maximum figure, which is supplied to the developers for the purpose of dimensioning the cooling system. In reality, in spite of the higher FSB, the power loss is significantly lower than this theoretical maximum value.

In introducing the Execute Disable Bit (EDB), Intel is providing a security feature in the new Pentium M. Viruses can certainly cause mischief in notebooks, just as they do in desktops, a fact that AMD evidently recognized a good deal earlier. After all, their Mobile Athlon64 has already featured a very similar virus protection function for several months now: Enhanced Virus Protection (EVP). AMD's EVP and Intel's EDB both basically work according to the same principle, in that code not meant for execution in the main memory (such as a virus) is labeled as being non-executable by setting this bit. With Service Pack 2 installed, Windows XP recognizes this feature, so viruses and other malicious software can no longer use the traditional buffer overflow exploit - Windows will not allow the code to be executed.
Intel informed THG that future devices will feature an option that allows the function to be disabled in the BIOS if required. This will be particularly important in the business sector, where older software is still frequently used that cannot run when the EDB is enabled.
