How to distinguish the good and bad of this book from the computer configuration list

From CPU frequency model, memory capacity, memory frequency, video memory capacity, graphics card chip, host chipset, etc.

In general, the higher the value, the better. For example, 2G of RAM is better than 1G, and 1G is better than 512M.

orz...Others are hard to tell.

CPUs with the same frequency should be considered from different angles. For example, L2 caching. Calorific and the like.

It's better to find someone to watch.

It's hard to say.

The performance of this book is directly proportional to the price.

Buying a book still depends on heat dissipation, the same performance, the same parameters are nothing to compare, mainly look at heat dissipation.

It's best to let the old birds around you help you make a reference when you look at a machine, there is no absolute good or bad computer, and it should be configured according to your usage.

This is difficult at first, because there are many brands of computer accessories, and if you don't have enough experience, you can't figure out which brand is good! Different brands of parts** are very different, and the other is the parameters of the hardware For example, graphics card gf8500 512MB video memory This is just the configuration given to you by JS, but it is very greasy in it, and the brand is second.

Among them, look at the process bit width, etc. The same is the graphics card of GF8500 512 DDR2 and DDR3 The process ** is much worse 64bit and 128bit or even higher bit width** is much worse Some people say that the same graphics card is 8500 512MB of video memory, why are you much more expensive than others, I said that it is worse than some rookies do not understand important parameters.

This one is too complicated to mention.

Learn slowly, and you will understand it over time!!

It seems that you want to match yourself with a computer, don't want to buy a brand machine, then you can go to your computer city to ask a few more, take a few copies of the configuration they wrote and ** come back to find an experienced friend to discuss, and then compare your own psychological price It is best to ask a few more experienced friends, sometimes the compatibility is not very good

There are generally the following ways to identify notebook configurations:

Outer packaging identification method: Generally, there will be a notebook configuration description on the outer packaging box of the notebook, and you can check whether the configuration on the outer packaging is consistent with the configuration you know and want to buy.

Software testing method: install the test software on the laptop, such as: "Master Lu".

Once the software is installed, there will be a detailed description of all hardware parameters in its "Hardware Overview" to check that the configuration is correct. And you can also test the notebook through the software, and know how the notebook performs.

Choosing a laptop is similar to picking a desktop, mainly looking at the hardware, and then paying attention to heat dissipation and workmanship. Good and better, the key is to match the computer according to your own needs, and pay attention to the following aspects when looking at the hardware:

Look at the performance of the motherboard. The motherboard, also known as the motherboard, directly determines the stability of the computer.

Look at the model number of the CPU. Now it is generally more than four cores, and it depends on the frequency of its operation, the power consumption, and the best is the Intel platform.

Look at the size of the memory. I recommend that it is 4G or above, and the larger the memory, the faster the machine will run.

Look at the quality of the graphics card. Now it's all discrete graphics cards, and I recommend that the video memory be more than 1G, and it also depends on the bit width and frequency.

Look at the speed of the hard drive. Now SSDs are starting to take over the market, more than ten times faster than HDDs, and the budget is enough to install SSD.

Look at the exterior styling. Match it according to your personal preferences and your budget.

You click on My Computer, and the basic properties of your PC are displayed. Take a look at what you want from your computer versus what you value to your computer. Some processors are not as good as quad-cores.

Look at what you're going to do with your computer. Generally, if you buy a computer, you still ask a friend who understands computers to help you take a look. Otherwise, dealers are fooling people.

Look at the CPU

Graphics card, mainly graphics card, now the CPU of the notebook is competent, that is, the graphics card is poor, even if it is a 256M graphics card, there are only 8 or 16 stream processors, and the more stream processors, the better.

Motherboard, CPU, graphics card, memory, workmanship, etc.

Better quality notebooks can be selected HP, Dell, Lenovo, and whether the configuration of ThinkPad is mainstream and good or bad can only depend on experience.

The current mainstream configuration is generally.

CPU: T4200 T6500 P7350 memory 2G

HDD 250g 320g

Graphics: Integrated x4500 , discrete gt105 gt110 gt 130 or hd4330 hd4570, etc.

Sony's is good, Lenovo's is also very good, and Dell's is more durable

How to look at the laptop configuration.

For many novices, how to check the quality of their computer configuration is a more tangled problem, and even sometimes there are some misunderstandings, in order to let everyone have a deeper understanding of the hardware, the following will dedicate a little bit of their own shallow views to you.

The motherboard takes a look at the number of cores of the CPU.

At present, the mainstream is dual-core, single-core (such as Pentium 4) has long been discontinued, and the high-end has quad-core.

Second, look at the production process.

The current 45nm CPU is popular, the previous generation was 65nm, and the older 90nm (rare). The manufacturing process of 45 nanometers refers to the width of the wire connection between the transistor and the transistor (referred to as the line width), which simply means that it can be on the chip in the same area"Squeeze"More transistors, more sludge centrifugal dehydrator transistors bring higher performance. Even if the number of transistors does not increase, the area of the chip can be reduced accordingly, so that the power consumption and temperature can be reduced by a lot.

Third, look at the size of the L2 cache.

The CPU is in the computer"Run"Sometimes, because it runs too fast, other hardware such as memory can't keep up with it, so CPU manufacturers have introduced caches. Judging the quality of the CPU by looking at the size of the second-level cache is mainly for Intel's CPU, because Intel's CPU relies heavily on the second-level cache, Intel's CPU second-level cache is mainly used to store data, and the first-level cache stores the address of the second-level cache, and these data are numbered such as a-z in the first-level cache, and the CPU needs to retrieve the data directly from the first-level cache when the number of the data is retrieved, for example, For example, the L2 cache is the content of a book, and the L1 cache is the directory of the book, which is why Intel's CPU L2 cache is particularly large, while the L1 cache is particularly small. AMD's CPU design is different from Intel's, AMD's CPU Level 1 cache is used to store the most commonly used data, and the Level 2 cache is used to store more commonly used data, so AMD's CPU Level 1 cache and Level 2 cache are about the same size.

Theoretically, Intel's CPU is more efficient, and the CPU can directly retrieve the number when it needs to retrieve some data.

Does the landlord refer to the level of computer configuration from the hardware parameters? (This one is easier to learn).

Or is it to see if the hardware is refurbished or defective? (It's hard to see this, it's hard to see if you're not a professional who does this).

It's very simple, get a Master Lu test, and there is a score judgment on it.

Don't forget to turn on the host to see if it's been a long time

You can go to Zhongguancun to have a look.

1.First of all, you need to have a certain understanding of the computer, such as knowing the current mainstream configuration and the parameters of each hardware, so that you can have a comparison.

2.You can go online to check the quality of each hardware one by one, make horizontal comparisons, and you can query **, which also largely determines the quality of the quality.

3.Also, don't just look at the parameters of the hardware, but also look at the brand, although some garbage brands have particularly high parameters, but the quality is particularly inferior.

4.Note that the collocation of each hardware should be coordinated, so that the performance of each hardware can be fully utilized when it runs.

Look at the CPU first, Intel's CPU has a lot of prefix names, like Atom, Core, Pentium, and generally Core is the best, especially i7, which is a flagship, and a server processor Xeon, with stronger performance.

The AMDR7 series is very powerful, equivalent to the Core i7

Graphics cards are divided into AMD and NV

The strongest among AMD is the dual-core card King Daul Pro, followed by the RX480 RX470 RX470D RX460

There are also older FRUY series such as the R9 390, which are very powerful.

The strongest NV is the GTX1080Ti and GTX Titan X (Passaca architecture), followed by the GTX1080, GTX1070, GTX1060, etc., which are very powerful.

CPU, hard disk, memory, graphics card, etc.

memtest

The memory detection tool, memtest, can not only thoroughly detect the stability of memory work, but also test the ability to store and retrieve data at the same time, which can well detect the quality of memory for us. After running a memtest test starts, memtest displays the test progress and the number of errors found in real time during the inspection process. If the memory passes 100% of the memtest's detection, and the number of errors found is 0, then the quality is trustworthy.

GPU-ZThrough GPU-Z, we can intuitively view the name of the graphics card, chip code, manufacturing process, chip technical parameters, DirectX support version, memory type, capacity, bus width, memory bandwidth, core video memory working frequency and other important information, no longer afraid of JS in frequency, display core, video memory bit width or video memory capacity.

mouserate

MouseRate is a software that measures the combined performance of the DPI and scan rate of a sample mouse. mouse

The average frequency of rate is the average opening value of all frequencies of the mouse when it moves, which can reflect the speed of the mouse from one side, and the number in the white box can show the stability of the mouse. The greater the difference in scores, the more unstable the mouse, and the larger the score, the faster the mouse.

The better the performance. cpu-z

CPU-Z can not only correctly identify the model of the processor, but also provide quite comprehensive detection information, including the processor's name, core code, manufacturing process, core voltage, multi** instruction set, core frequency, frequency doubling, bus frequency, number of cores, and cache capacity at all levels. This allows users to determine the true model of the CPU and whether it is being overclocked. In addition, CPU-Z can also detect some relevant information about the motherboard and wheel memory, such as the model and version of the motherboard's south and north bridge chips, the hidden order of the memory when working at different frequencies, and whether the dual-channel memory function is enabled.

hwmonitorpro

HWMONITORPRO is a new software for CPUID, which does not seem to meet the detection function of CPU-Z, this software has the characteristics of real-time monitoring, and inherits the fine tradition of installation-free. Through the sensor, you can monitor the voltage, temperature, fan speed, memory voltage, motherboard north and south bridge temperature, hard disk temperature, graphics card temperature, etc.
