| | Intel processors today and tomorrow |
 | | Pentium XE 840 processors support the Intel Extended Memory 64 technology (support for 32-bit and 64-bit addressing), Hyper-Threading (up to four software threads simultaneously), Execute Disable Bit (if supported by the operating systems, protects against viruses that exploit memory buffer overflow errors). |
 | | Pentium D 840, 830 and 820 chips with support for the 800 MHz system bus are supplied in the FC-LGA4 package for the 775-pin LGA775 socket. |
 | | Talking solely about modern Pentium M processors, their current implementation on the Dothan core offers 2 Mb of L2 cache deliberately optimized for reduced power consumption, enhanced data pre-fetcher, which lowers the requirements to accessing the memory positioned outside the chip and increases availability of L2 cache data. |
