What is the difference between a normal CPU and a server CPU

Of the CPUs currently produced by Intel, Pentium 4 and Celeron are PC-oriented, Xeon, XEONMP, and Itanium are for workstations and servers. Where Itanium is a completely different 64-bit CPU from other CPUs, the design is not considered for existing Windows applications. While other processors vary in their maximum operating frequency, FSB (front bus frequency), and cache size, the internal design is essentially the same while ensuring software compatibility. The biggest difference between Pentium 4 (Celeron) and Xeon (Xeon) is that Xeon can build multiprocessor systems, and P4 does not. The P4 system can only use one cpu,xeon to build a dual processor system with 2 CPU, and XEONMP can build a system with more than 4 CPUs.

Multi-processor system can be used in 3-D graphics and animation file encoding, such as a single processor can not achieve high processing speed applications, but also in the server database processing, such as high load high speed applications. In addition, P4 uses a 478-pin package, Xeon with 604-pin encapsulation, and the chipsets that support them are also different and therefore cannot be used interchangeably.

AMD also produces Athlon MP processors for workstations and servers. Its internal design is essentially the same as Athlon XP, but it supports dual CPUs. In addition, the CPUs such as Sun's UltraSPARC and IBM's power are also server-oriented and can form CPUs of multiprocessor systems, but they are incompatible with Intel and AMD's CPUs on both software and hardware.
