There are two points to note in the configuration of the E8400.

1.The memory bandwidth should be greater than, or at least not lower than, 1333 MB bandwidth.

2.The recommended rated output of the power supply is 400WNote that the graphics card is powered by dual 6pin power supplies.

You can save some money with the AMD platform, 545,550 The performance is close to 945,955 after the core is opened, the Intel platform E8300 is scattered, and the E6300 is the most cost-effective.

Three years later, the 15nm U has come out, and the mainstream games and software will definitely be more BT, and the requirements for the CPU and graphics card are higher, and it is simply unrealistic not to upgrade.

The parameters of the E8400 CPU are as follows:Core type: wolfdale.

Production process: 45 nm.

Frequency:. External frequency: 333MHz.

Octave: 9x.

L1 cache: l1=128.

L2 cache: l2=6144.

FSB frequency: 1333MHz.

CPU socket type: LGA775.

Number of pins: 775pin.

CPU Cache (KB): 6MB.

Evaluation. As a 45nm processor for the mid-to-high-end dual-core processor market, the E8400 can be said to perform very well. Not only has it made great strides over the previous generation of 65nm products in terms of technology and specifications, but it has also made a qualitative leap forward in terms of overclocking potential.

And because the 45nm process will be lower in cost, the new Intel 45nm processor will be more impactful in the competition in the low-to-mid-end market.

The E8400 CPU parameter is 3GHz.

The E8400 processor belongs to the Intel Core2 Duo (Core 2 Duo) E8 series processor, 45nm process technology, which is dual-core and dual-threaded, and does not support hyper-threading technology, the Core 2 dual-core E7 and E8 processors are products that appear during the transition from 65nm process technology to 45nm process, E4 and E6 are 65nm, and E7 is used to replace E4, so the performance of the high-end 65nm E6 dual-core is higher than that of some models of E7.

E8400 is also a high-end dual-core processor,The performance is OK,E8400Better than Q8200,In terms of games,Because it is hyper-threaded, it is the best performance in the old architecture dual-core and quad-core entry-level processors,Of course, it does not include the CPU of the new architecture,The first thing to note is that the dual-core and 4-core U can not be compared horizontally,After all, you can see a clear difference under multitasking。

CPU composition

1. Operational logic components.

The arithmetic logic component can perform fixed-point or floating-point arithmetic operations, shift operations, and logical operations, as well as address operations and transformations.

2. Register components.

General-purpose registers can be divided into two types: fixed-point and floating-point, which are used to save the register operands and operation results in the instructions, and the general-purpose registers are an important part of the processor, and most instructions have to access the general-purpose registers. The width of the general-purpose register determines the width of the data path inside the computer, and the number of ports can often affect the parallelism of the internal operation.

3. Control components.

The control unit is mainly responsible for decoding the instructions and sending control signals for each operation to be performed to complete each instruction. There are two kinds of structures: one is the microprogram control mode with micromemory as the core; One is a control method based on the logical hard-wired structure, in which the microcode is kept in the micro-storage, and each microcode corresponds to the most basic micro-operation, also known as the micro-instruction.

It turns out that the E8400 is very good. Massive L2 cache at the main frequency. But now the performance is not as good as that of the old Core i3 530.

There is no value for money anymore. But it's still much stronger than the E5400. The E8400 has been discontinued.

Even if there is a box, it is a second package. It is recommended to buy in bulk. As for the fan.

Overclocking. With a fan of around 60 will do. For example, overclocking the three Red Sea Standard Edition.

The overclocking amplitude depends on the quality of the body. It should not be a problem to be electrocute and air-cooled.

Advantages: Fast speed, 6M cache like flying feeling. I took a second-hand shot a few days ago on the Internet, 100 yuan, the temperature control is not bad, and the temperature when the main frequency is running is not very low.

Disadvantages: In fact, it is not a disadvantage, but to deepen the understanding of frequency doubling. This U doubling is between 6-9, what energy-saving and intelligent functions are turned on, it may run at the lowest octave, is 6*333=1999MHz(; Turn off energy-saving technology, and that's it.

This one needs to be detected by the CPU-Z detection software to know, and Master Lu has been displaying the frequency doubling 9, the default main frequency, and the CPU-Z display is the real rate that is running at that time.

Summary:Master Lu turns on the intelligent cooling function,The frequency doubling will drop to 6,The main frequency is running,It seems that it has never changed,I really can't feel the use of this U's high main frequency。 After turning it off, it keeps switching between 6 and 9, and the program runs when it is open for a long time, and it runs on standby, and the running speed at this time also flies.
