Ask a few questions about Intel Xeon CPUs

Xeon processors are divided into three families, from low to high.

Xeon 3000 series only supports a single socket (that is, only one processor can be used on a motherboard), and the processor interface is the same as that of mainstream desktop processors, which are LGA775 and LGA1156

The Xeon 5000 series supports dual sockets (that is, one motherboard can host two processors), and the processor interface is the same as that of the highest-performance desktop processor, which is LGA1366

Xeon 7000 series supports multiplexing (that is, a motherboard can only host multiple processors, 2 "number of processors" 32), and the processor interface is LGA1567

Compared to home processors, Xeon processors are optimized for instruction sets for virtualization and commercial software. Secondly, the stability of the processor is also much better than that of the home. The performance is similar to that of home processors with the same chip and main frequency. However, there is a lot of difference.

The only drawback of Xeon is that the thermal power consumption is relatively large.

**The server should of course choose a server-specific operating system, if it is a PHP environment, Linux system (Redhat Linux, CentOS Linux) is highly recommended; If it is an environment, then you can only choose the Windows system, and the version is recommended Windows Server 2003 2008

The advantage of Xeon is that it is relatively fast and easy to use, and the disadvantage is that it is expensive.

Highly recommend Intel 4 core processor! It's like the i7 i5.

AMD also has a 6-core one, so of course it's even better.

You can buy whichever of you is cheaper.

A small server i5 is sufficient.

If you are used to the system, you will be xp.

But I think Windows 7 is better!

1 Xeon is more stable and durable, and civilian CPUs cannot reach that level.

2 This set you said, there is no problem with the group ** server.

It makes the most sense to install the NT system.

Zhiqiang CPU is stable and good. It's not clear what system to install.

Good core.

There are also the following differences between Xeon and Core:

1. Xeon is a CPU for servers, with larger caches and stronger stability, and some server-specific instruction sets with large data throughput. The Core i-series is a desktop-class CPU.

2. The performance is not much different from the ordinary core, at least it is disproportionate to the huge gap in **.

3. Xeon processors do not have integrated graphics cores, while the Core i series has integrated graphics.

The two sets actually serve different purposes:

The Core i is a civilian series, and the Xeon is a server series. Many of their features are different, but the most important and simplest performance differences can be roughly understood.

Here we only talk about the core of the desktop part, because after all, it corresponds to the Xeon on the server side. Core i3 i5 i7 mainstream models in 2 4 cores (i7 high-end series not counted), three slow in 3MB-8MB, i3 for dual-core four-thread, i5 for four-core four-thread, i7 for four-core eight-thread, their single-core performance is generally better, because the use is civilian, the use of all kinds of special software and games is the main one.

Xeon E3 E5 E7 is quite different, E3 is very close to i7, the same is four cores and eight threads, the frequency is generally lower than i7, equivalent to the cost-effective version of i7, in the 4th generation and before, E3 is very popular with the installation party.

E5 and sliding chain E7 cache is very large, in addition to individual models, they have a large number of cores, for example, E7 8890V4 The number of cores has reached 24, 48 threads, L3=60MB, the main frequency is relatively low, because its purpose is a server, multitasking is more important, playing an interstellar 2 game, i3 6100 is much easier to use than it.

First of all, Intel E3, E5, and E7 represent 3 different grades of Xeon CPUs, and the Naming of Xeon's "Xeon Series" (Xeon E3, Xeon E5, and Xeon E7) is somewhat similar to Core i3, i5, and i7 on the desktop; A more understandable explanation is that it can correspond to our luxury Sakura car manufacturer BMW 3 Series, 5 Series and 7 Series. Corresponding to the good, better and best respectively.

Intel Xeon E3 is generally a single processor。The E3 is a single-socket processor series for workstations and entry-level servers, with two sub-series, the E3-1100 and E3-1200, all of which are four-core except for the E3-1220L, which is dual-core, but are available in four-thread and eight-thread models. XEON E3 has the fastest update speed, updating with the consumer-grade Core i7 every year, and the socket is also the same as the consumer-grade product, using LGA 1155 and LGA 1150, and the model of the first, second and third generation products is E3-1200 E3-1200V2 E3-1200V3.

The Intel Xeon E5 is generally a symmetrical dual processor. The Xeon E5 is a processor family for high-end workstations and servers, which is updated annually, but the architecture lags behind the Xeon E3 generation. In Q3 2013, Xeon E5 was updated to the Ivy Bridge microarchitecture.

At the same time, Xeon E3 was updated to the Haswell microarchitecture.

The Xeon E5 has five sub-series, the entry-level single-socket processor series E5-1400, the high-end single-socket processor series E5-1600, the entry-level dual-socket processor series E5-2400, and the mainstream dual-socket and quad-socket processor series E5-2600 and E5-4600, the former two using LGA 1356 and the latter two using LGA 2011.

Intel E7 is generally symmetrical quad processors, or even symmetrical eight processors. The Xeon E7 is a family of processors for mission-critical and data centers with an emphasis on reliability, availability, and serviceability (RAS).

The first generation of the Xeon E7 is available in three sub-series, the top-of-the-line eight-, four-, and dual-socket processor families, the E7-8800, E7-4800, and E7-2800, supporting up to 4TB, 2TB, and 1TB of memory, respectively. Codenamed Westmere-EX, the entire line supports quad-channel memory technology and uses the LGA 1567, which is also the series that uses this socket.

The second-generation Xeon E7, codenamed IVY Bridge-Ex, provides three sub-series E7-8800 4800 2800V2, all models support maximum memory, using LGA 2011, up to 15 cores and 30 threads. The eight-way XEON E7 supports up to 12TB of memory. Despite the same name, the LGA 2011 is exclusive to the XEON E7 and is not compatible with the XEON E5 or Core i7.

1. Product positioning:

Intel Xeon CPU it is used for"Intermediate range"of business servers and workstations.

Core i-series CPUs are mainly used in personal computers.

2. Integrated graphics card:

Intel Xeon CPUs don't have integrated graphics cores.

The Core i-series CPUs are equipped with integrated graphics cores.

3. Main frequency:

Intel Xeon CPU has the highest dynamic acceleration at the main frequency.

Core i-series CPUs are clocked at GHz, which can reach GHz with Intel Turbo Boost technology.

The main differences are:

Xeon CPU:

2.Core i-series CPUs:

The specific data is as follows:

Xeon is a server CPU, with a large cache, strong stability, and some server-specific instruction sets with large data throughput.

In terms of performance, it is stronger than ordinary CPUs, especially E3, close to the performance of i7, only a little higher than i5**, so there are also ordinary players with E3.

Xeon processors do not have integrated graphics cores, and most ordinary CPUs have integrated graphics cards.

Zhiqiang CPU can check two or even 4 CPUs on one motherboard (motherboard support is required), while ordinary CPUs are generally one motherboard and one CPU.

No. Xeon processors have more cores than Core's. Multipliers are more than Core's. The external frequency is about the same. But the Xeon ones are very expensive. Generally, it is used as a CPU for the server....If you play a lot of games, it's better to use Xeon.

But if you want to play games cost-effectively, AMD is better.

To put it simply, the Xeon series focuses on multitasking performance, and there are relatively large restrictions on the processing capacity of a single task, while the i series focuses on desktop performance, for a single task can occupy CPU resources as much as possible, such as i5, i7 with high-end graphics cards can be fully turned on games, Xeon is difficult to achieve, the reason is that the game program can not fully use Xeon performance, and Xeon's chipset basically does not support high-end graphics cards, because there is no need for this... For example, the Xeon platform can handle more than 100,000 IIS connections at the same time, while the I-series platform is estimated to strike a few thousand.

Haven't you seen the reviews? The i7 2600K outperforms the new Xeon.

No. Xeon processors have more cores than Core's. Multipliers are more than Core's.

The external frequency is about the same. But the Xeon ones are very expensive. Generally, it is used as a CPU for the server....

If you play a lot of games, it's better to use Xeon. But if you want to play games cost-effectively, AMD is better.

Looking at the specific model, the Xeon model has more than the Core i5 and i7 combined. There are models with similar performance to i5 and i7. There is a model with a much higher number of cores than the i7.

The game is still better than i7, Xeon is aimed at servers, generally multi-core, low frequency. General game optimization can't make use of too many cores, so it relies more on the CPU clock speed, while the i7 clock speed setting is generally higher. If you can take full advantage of the multi-core advantage with software, Xeon is much stronger.

For example, E5 2699v4 runs AE rendering.

The same architecture must be strong, server level u

But it depends on the specific model.

Of course, it is better, the new architecture, the new process will bring low energy consumption and high efficiency. The performance is also better, of course, it has something to do with the main frequency. i integrates graphics and is somewhat better than the previous Intel graphics cards.

i7>i5>i3

You just know it when you look at it.

The core is at least dual-core and four-threaded, or above, i3, i5, i7 are all cores.

Pentium is still dual-core,E3400The main screen,E6700It seems to be.。

If you want to be good, use Core.

Core. There is no strict standard for dividing these two server-level processor families, but the following differences can be summarized from Intel's official description and actual processor specifications:

As a standard model of Xeon server CPU, E is generally used in small server configurations, and is relatively basic in terms of architecture specifications, and the main frequency is usually low;

As the extreme model of Xeon server CPU, X is generally used in medium-sized server configurations, and the architecture specifications are enhanced compared with E, and the main frequency is usually about 50% higher than that of E series.

According to the practice of the semiconductor industry, the essential difference between E and X is that the CPU of the same design is different in performance due to the random deviation of manufacturing. As a result, the TDP design of the X series is also significantly higher than that of the E series.

Pretty much the most, it mainly depends on the interface, architecture, number of cores, main frequency, cache, and instruction set. It doesn't matter if it's X or E or L or whatever.

In the past, it was generally accepted that Intel was more stable, but now this difference can be ignored.

As long as the heat dissipation is not done well, whether it is Intel or AMD, there will be heat dissipation problems, and there is basically no obvious difference between the products of the two companies.

There are two kinds of rendering and non-rendering, if you are doing rendering, it is recommended to use Intel's CPU with AMD graphics card for long-term work, if you don't render, you can choose it casually (NV graphics card must not be rendered for a long time, the consequences are very serious).

If it is a new CPU, it is generally the i-series, i3 i5 i7. If it is an E-series U server, it is cost-effective, stable, and has low power consumption. People who know computers can choose, and the general ones can use the i series.

CPU for servers

Overview of Xeon processors.

In the entire Intel Xeon processor family, we can see three names such as Xeon, Xeon DP and Xeon MP, and many readers are confused about these three names, what is the difference between them? In fact, these three names only represent two different Xeon processor sub-series, XEON and XEON DP are the same series, XEON is the abbreviation of "XEON DP". The "dp" is the meaning of "dual processor", that is, the processor that supports dual processing, and only the word "xeon" is marked on the processor, as shown in the left figure of Figure 1. The "MP" in Xeon MP stands for Multiprocessor, that is, a processor that supports multiprocessing, and the full "Xeon Processor MP" is marked on the processor, as shown in Figure 1 on the right.

Figure 1 In this way, you may understand that Xeon, or Xeon DP, is an Xeon processor that supports dual processing, and Xeon MP is an Xeon processor that can support multiple processing (usually more than 4 channels). In fact, there are three major parts in the entire server processor field, that is, single processor, dual processor and multiprocessor, single processor is a processor that only supports a single processor in the same system, such as PC processor, dual processor is currently only used in servers and high-performance workstations, and multiple processors are usually developed specifically for servers.
