The 64-bit Xeon Processor One month ago Intel officially
released their last processor that hadn't a 64-bit version: Xeon
XP. Xeon MP is a processor target to multiprocessor servers with
four or more CPUs, based on Pentium 4 microarchitecture. This
new Xeon MP model is also known by its code-name Truland and
Intel also has released a new chipset for it, Intel E8500. This
new CPU has some new features if compared to the previous Xeon
MP model: - Clocks from 2.83 GHz to 3.66 GHz. - EM64T
technology, allowing memory addressing up to 1 TB (it uses a
40-bit address bus). Due to limitations on the memory modules
found on the market today, this CPU is limited to 64 GB of
DDR2-400 memory. However, with the FB-DIMM memory release this
limit will probably increase. - 667 MHz external bus. - 1 MB L2
memory cache. - L3 memory cache up to 8 MB (the exact quantity
depends on the model). This memory is locate on the processor's
body, but not in its core (die), but in a silicon chip located
besides the processor silicon piec
