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 compat
Among the CPUs currently produced by Intel, Pentium 4 and celon are PC oriented, while Xeon, XeonMP, and Itanium are for workstations and servers. Among them, Itanium is a 64-bit CPU that is completely different from other CPUs. It is not designed for use in existing Windows applications. Although other processors differ in the highest operating frequency, FSB (Front-End bus frequency), and cache capacity, the internal design is basically the same, wh
IPC (Instruction per clock):Number of commands executed by the CPU per clock cycle
In fact, the frequency and IPC really affect the CPU performance. Accurate CPU performance judgment criteria should be:CPU performance = IPC (number of commands executed by the CPU per clock cycle) x frequency (MHz clock speed)This form

When we use the top command to see the system's resource usage, we see load average, as shown in. It represents the average workload of the system at 1, 5, and 15 minutes. So what is load? How does it relate to CPU utilization?Load average: The system average load is the load of the CPU, which contains information that is not CPU usage, but rather statistics on t

In Windows, the operation system does the allocation for you based on CPU usage. you can set the affinity but, it will not determine which processor you run on. on the Xbox 360, the affinity is needed otherwise the 360 will not allocate your threadA s
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.

Svchost.exe is a core process of Windows XP systems. Svchost.exe not only appears in Windows XP, but there are svchost.exe in Windows systems that use the NT kernel. Typically, the number of svchost.exe processes in Windows 2000 is 2, and the number of svchost.exe processes in Windows XP rises to 4 and more than 4.
