Tom’s Hardware Guide CPU Guide: The Final Battle: P4/2400 vs. Athlon XP 2100 (2400 ) – New RDRAM With 32 Bit, Bundled With Motherboards There are some new developments with RDRAM, which will be available in two different versions in the future: the standard 16-bit will be offered, as will a 32-bit version, which will differ mechanically from previous modules. Asus plans to be the first manufacturer to offer 32-bit memory (Kingston) bundled with its P4T533 motherboard in May. Samsung and Infineon will forgo production of 32-bit modules entirely after PC1066. Infineon will go so far as to offer only PC800 modules for 400 MHz.
