What is the difference between the server CPU and the normal CPU? Below we find a professional literature, quickly to increase knowledge. Overall, there are six main differences between the server CPU and the common computer CPU, so let's look at it together.
One, the instruction set
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
