What are the difference between the Pentium® III processor and the Pentium III Xeon® processor?
The Intel® Pentium® III Xeon® processor was designed for workstations and servers. Workstations tend to be the workhorse of computers and servers need to be reliable. For some Intel Pentium III Xeon processors, the main difference would be the larger cache size of 1 MB and 2 MB cache sizes. Workstation and server applications can see a significant performance increase with the larger cache.
The Pentium III Xeon processor at 600 MHz+ includes an SMBus interface that allows access to several processor features, including two memory components (referred to as the processor Information ROM and the Scratch EEPROM) and a thermal sensor on the Pentium III Xeon processor at 600 MHz+ substrate. All of these new features combined with the additional signals used in the SC330 package/connections are used to monitor the actual power source outputs and core temperatures to make sure that the processor is running as expected. As a result, the Pentium III processor offers higher reliability.
