How to compare server processors (CPU)

Unlike shared hosting and virtual servers, hosted dedicated servers offer you management over your selection of processor (CPU). Here’s some data to assist you compare processors once shopping for dedicated servers.

How to compare server processors (CPU)

Processor options

The Central process Unit (CPU) in your server, additionally noted merely because the processor, is what interprets and executes directions, process knowledge and acting tasks like serving websites, running info queries and corporal punishment different program and computing commands. The additional processors in a very server, the quicker and additional expeditiously the server is capable of operating, and therefore the additional directions is dead in a very shorter house of your time.

How fast a processor works depends part on the clock speed, that is that the speed at that the processor executes directions. The quicker the clock, the additional directions the C.P.U. will execute per second. it’s the processor speed, measured in hertz (GHz).

But as processors progress, enhancements in chip design mean that regardless of the clock speed, a processor will execute additional directions at the same time, because of things like multiple cores, multiple threading, subcycling, redoubled knowledge outturn and reduced latency.

Most modern hosted servers provide multi-core, multithreaded processors, which implies that one superb processor might perform additional tasks, additional expeditiously and quicker than 2 or additional lesser or older processors, notwithstanding the latter have a quicker clock speed.

Multi-core means a server truly has quite one processor core operating to finish the tasks demanded by its users. though a 4-core processor won’t essentially be 4x quicker than a single-core processor, it’ll still be ready to execute directions notwithstanding one or additional of the cores is being totally utilised, instead of obstruction. Multithreading additional improves performance by permitting multiple threads of code, or multiple elements of a method to be dead at the same time.

Another necessary specification of a processor is that the cache memory, memory that reduces the time required to access knowledge from the most memory of the server. The cache memory permits the processor to store and access oft needed knowledge far more quickly. the upper the cache memory, the broader the range of knowledge that may be control in cache, dashing up the performance of the processor.

Beyond these employment multipliers, every generation of processor chipsets brings with it enhancements in chip design designed to extend the speed and capability of performance, by reducing latency and increasing outturn at varied stages of the computing method.

According to Intel, their latest Xeon E5 chipset v3 “Haswell” version provides a 3x performance improvement over its forerunner, and a 12x improvement over its 4-year recent counterpart, the corporate citing a range of subject enhancements throughout its launch.

Intel Xeon E5 v3 dual-socket servers support up to thirty six cores and square measure among the few processors that square measure compatible with the new DDR4 RAM version that uses immensely reduced power consumption and provides superior knowledge transfer speed.

Look on the far side the processor

Remember that once selecting an avid server hosting supplier, there’s far more to server performance, to not mention service performance, than the processor alone.

For example, a high processor clock speed can cause bottlenecks unless the server’s bus clock speed is equivalently high, therefore you wish to be assured that the servers square measure well built to urge the most performance from every component of the hardware.

All of the hardware parts in a very server square measure mutually beneficial, and exploitation the foremost powerful processor obtainable might not be the optimum resolution if your employment needs higher levels of RAM, the improved disk performance of Solid State Drives (SSD), or the redundancy of RAID technology.

Choosing a processor

Optimizing the cost-benefit of processor performance, similarly as that of the extent of RAM, and therefore the sort and size of storage and RAID in your server, depends entirely on however you propose to use the server. It depends on the intensity and therefore the nature of the server’s employment.
