Probably not to find now such a PC user,which would not have heard of the servers. Many people almost know what it is. But they say little about their internal structure and mostly narrow specialists. This article will discuss server processors. What are they for, what are they, and how are they different?
Since the server is a system, constantlyoperating with large data streams, then the load on the "iron" can sometimes reach colossal dimensions. Simple processor solutions for home use here will not work. For this purpose, there are special server processors. They are able to solve several typical tasks for this area:
Since the load on such systems is several times greater, many physical parameters should be considerably higher than household analogues.
Server processors, as a rule, are equipped with a large number of computing cores. For example, their number can reach 12, although for stationary versions it rarely exceeds 8.
Sometimes servers can use a system with several processors connected simultaneously. That is, each of them must be able to work together, with no glitches and glitches.
Technically, a server processor should be able to support and work with a large amount of memory. This is very important for powerful stations.
In general, consider the server processor inbreaking away from the whole system is a bit wrong. The performance will be affected by all the "hardware" in general. Correctly matched motherboard, high-speed hard drives, fault-tolerant large-scale memory.
As you know, in the world there are only two major manufacturers that can provide both home and server solutions. This is AMD and INTEL. Consider their devices closer.
It is under this brand that AMD server processors are manufactured. At the moment they are presented in three groups, depending on the architecture and scope of application:
A basic server processor capable of efficientlypractically in any configuration. It carries 16 computing cores, which, in fact, provide good performance. The shared L3 cache is 16 MB. The processor clock speed reaches 2.8 GHz, and in Turbo Core mode - 3.5 GHz.
Against the backdrop of low prices, this product is great for creating cloud servers.
This solution is a development on the technology "System on a chip." The architecture used is ARM. In the series there are varieties of 4 and 8 nuclear processors.
The flagship of the whole family was SoC A 1170 with a frequency of 2 GHz and with 8 cores.
This is the first representative of server processors withhybrid architecture. That is, as a source of performance can act as the main processor, and graphic. This model has 4 cores with 1.9 GHz and 2 MB cache memory.
This solution can be used in small server systems.
Server products from Intel are represented by a whole set of Xeon devices, as well as Atom and Itanium lines.
Intel Xeon server processor, designed for large network loads and powerful servers. Made by technology 14 Nm.
The processor works tirelessly with as many as 24 cores in 48 threads. The clock frequency of each is 2.2 GHz, and with the use of TurboBoost technology and up to 3.4 GHz. The cache memory is very large - 60 MB.
The standards of memory DDR4 and DDR3 are supported. At the same time, its maximum volume, with the use of the processor can be up to 3 TB.
The entire line of Intel Xeon E3 processors is positioned as a solution for small servers, cloud workstations and the Internet.
This representative is collected using 22 Nmtechnologies. Has on board 4 cores, working in 4 streams. Their base frequency is 3.1 GHz. If you use Turbo Boost, you can grow up to 3.5 GHz. The processor cache memory is 8 MB.
Supports DDR3 memory. Its maximum size is 32 GB.
These processors are focused on creatingmicro servers, small data warehouses and the Internet. Thus, Intel has created an inexpensive tool aimed at solving typical problems of small and medium-sized networks.
The architecture used in the processors is 64-bit. Available versions with 2, 4 and 8 cores with a maximum frequency of 2.4 GHz.
Judging by the responses of the first, who tested thisprocessor, in terms of performance, it is inferior to all Xeon. However, due to low cost, power consumption and less need for support finds its application in certain niches.
Choosing a server processor is not an easy task.There are many parameters to consider: simultaneous use of resources, the frequency of circulation, the density of requests, the total amount of data, and much more. But if you approach the matter carefully, you can always find the optimal solution that can cope with the required task without overpaying it.
