How to distinguish the performance of a PC?

September is the back-to-school season.Many students are aheading for new college life after a long 2 months summer vocation.This period is also the peak season of electronic manufacturers ,especially for the computer market.Since the PC has become a necessity for post-90s.However,many students are laymen of choosing a computer,let along distinguish the goodness of a PC.In the following passages,I’ll teach you how to distinguish the performance of a computer as well as how to choose you ideal PC.

A laptop or a desktop ?Maybe the first problem you should confront with.Since the laptop has a unparalleled advantage compared with the traditional desktop is the portable feature.You can take it to everywhere as you like, which the desktop can never provide your the convenience.There has a big difference in programming between the laptop and desktop.The most prominent distinctive is the computer radiator.The desktop has a big mainframe with a CPU radiator fan while the laptop has only a small computer cooling pad.Cooling has been a problem troubled the manufacturers for a long time.

Every coin has two sides.This old saying also suit for choosing a laptop or a desktop owing to they both have their own merits and weak point.Hardly a conclusion can draw due to the differences of the price, performance ,computer configuration and so on.It all depends upon the customers own perspective.Nevertheless,we can still find some common benchmarks of choosing a computer totally ignore its a laptop or a desktop.

First of all,you should go to your local computer mall to get some information of the well-known brands such as,Apple,Dell,Sony,Lenovo ect.You can compare the computer configuration between the brands and then decide which computer configuration suit you most.If you are a game addict,you’d better choose a high-end of a mainframe computer configuration.Thus you won’t be interrupted when you are in a MMOG ( massive multiple online game).Vice versa if you only use the PC to chat or see movies the request of the configuration could be lower.

Then you should know some major devices,such as CPU,the capacity,Computer graphics.Only a few style of CPU exist in the market such as Intel,AMD,Athlon XP…But there is no need for you to learn all of them, you can choose the Intel which is the best.What’s more,you can never choose the integrated computer graphics which proved to be not very good.As for the capacity,the best way of distinguish it is to compare and it should also meet your needs.

In a word,the more brands and information you know,the easier you distinguish the performance of your computer.So before you buy a PC to gather as much as information as you can or ask a friend who know the knowledge of computer.I hope the way of my own purchasing PC will be helpful for you.

Dell Studio 1747 Laptop

Dell Studio 1747 is available in light blue box. A set of simple supplies: notebook , battery, power supply, drives to reinstall. Wheels - emergency decision, because on the hard drive has a reserve for the restoration of the factory system state, which we will discuss in this article. But now, almost none of the manufacturers supplying a dell inspiron 1501 battery laptop optical drives for system recovery, at best, you can make them yourself. Therefore, the presence of disks I would refer to plus laptop, if staff drive will not work completely, at least be able to restore the operating system. Well, back up everything else - this is the sphere of responsibility of the user.

Black cover in barely visible speck of grayish and round with the same logo Dell. Because of the texture, it looks a little dusty. The upper part of the flat side faces sharp, the side face of the cover is a red edge. By the way, the front face is tilted outwards, for it is convenient to hang on when you open the lid. The course covers a tough, no no latch, the lid is held only on effort hinges. The construction of loops in this model the most fashionable: the lid is kept on the two large “ears”, and the axis around which the dell inspiron 1520 battery matrix is ​​located inside the housing. However, the opening angle here is not the greatest - perhaps 140-150 degrees.

The bottom cover of the simple little black rough plastic. However, in the desktop model is a justifiable decision, it is unlikely someone would see her bottom. Also worth noting is that the dell 1545 battery protrudes from the body strongly downward for more than a centimeter. Because of this, firstly, between the laptop and the surface on which it stands, formed a large gap, which circulates the air, and secondly, to create a space in which the works “sub notebook”.

The front panel has no connections with the ergonomic point of view, no complaints. At the same time pay attention to the red box in the roof.Connectors on the rear side of the casing there. It is interesting to look at the design of the battery and attaching the matrix to the body, but also noted that the exhaust ventilation grille goes to the rear face.In the photographs the side faces can be seen as a big dell latitude d600 battery raises the laptop above the desk and a gap is formed between the casing and the surface of the table.

The keyboard in Dell Studio 1747 supports the general impression: it unpretentious. Claims by the location of the keys I did not have, with almost all the keys you can work without any problems. From small quibbles should be noted that the dell latitude d820 battery block too far away from the cursor, they inconvenient to use together. However, most often begin to work with a numeric keypad. From the explicit cons relating to the layout, it should be noted that the digital block are shown only the actual figures - there is no notation keys to cursor mode.

Feels like the typing keyboard is not the best. First, the keys pressed loose, and remains the impression that they stagger from side to side. Although after a week where active work I’m used to the keyboard, and I even got to print at a fast pace, but will not say that work was good. Secondly, the keyboard is noisy at the end of the key stops tight. The keyboard is installed in the hull a little hump, the middle part just above the brim. But the backlash keyboard in my copy was not.In general, the keyboard is quite normal for a home hp 510 battery laptop, but for large volume printing is not very suitable.

With its new Satellite A350 Toshiba is investing properly in the screen itself. This laptop has: a wide screen of 16 inches.

Toshiba Satellite A350 follow the trend in terms of design with glossy piano black, like so many electronic gadgets are using nowadays. 16-inch screen is well suited for entertainment in the form of such films, and it has a resolution of 1366 x 768 pixels.

The computer has a processor type Intel Core 2 Duo T6400 at 2GHz, and you can get either 3 or 4 GB of internal memory. Both variants use two memory ports, which may be worth knowing if you buy it with 3GB and then thinking of upgrading to 4GB. The hard drive holds 320 GB.

At CES 2009 in Las Vegas Asus(Asus Eee PC 900 battery) continues to present new products, innovation is the watchword. The innovation that we see today is the new Asus Eee keyboard Keyboard, the Multimedia Keyboardbecause it combines a stylish finish, light and very slim design and new technical virtuosity.

What immediately leaps to the eye of the Eee keyboard is certainly the touch screen side that allows it to move quickly through the menus and multimedia online features used to the computer(Dell Inspiron 1520 Battery). This is Asus Eee Keyboard : One of the most interesting products booth at CES the company in Taiwan that moves away from the idea of having a keyboard as input device and just, but joined the concept of a separate device.

In practice it is an independent and integrated motor encased in a QWERTY keyboard. The diagonal touch-screen is 5 inches and touch screen replaces the mouse making virtual touch pad that lets you move among advanced features. Among those that stand out are definitely the work of handling of audio and videoAs well as the activation of the calendar, calculator or email.

The style is very white Apple. The keyboard is equipped Asus(Asus Eee PC 1000H battery) Eee Keyboard ’s ultrawideband HDMI to connect to televisions HDMI, two USB 2.0 ports, a VGA input, an Ethernet LAN, as well as inputs and audio outputs (speakers and microphone). Interesting point is the Wi - Fi 802.11 b/g/n. Keyboard Keyboard Asus Eee will be available by early 2010.

Asus notebooks(Asus Eee PC 900 battery) come from two advanced, based on the new Intel Core i7: it is specifically dell’Asus M60J and ASUS G51J, respectively designed for home entertainment and gaming, thus representing the true multimedia solutions.

The model M60J presents the very interesting features: it has a HD screen 16 “, supported by the chipset NVIDIA GeForce GTX 240 with 1GB of DDR3 memory as PA3534U-1BRS , is capable of displaying high definition images of excellent quality. The two 500GB hard drives, working in a dual-drive, you can create a vast archive of music, videos and movies.

• Edit summary assessment and advantages and disadvantages:

Throughout the history of the notebook, we found that consumers higher performance and better portability, longer life and better heat dissipation, and the pursuit of a more affordable price is eternal and unchanging, the ASUS U30J with 13-inch laptop(Dell XPS M170 battery) size were of high quality wire mesh enclosure design equipment, the final thickness of the thin body, feel comfortable operating the keyboard, rich practical interface, among others, is a very good thermal performance, give this book were well received.

Settings, i3-350 processor and chipset with HM55, 320GB 5400RPM hard drive, and comes with 2 GB memory DDR3 including apple a1036 adapter, while the independent implementation of NVIDIA Geforce 310M integrated graphics card and switching technology, according to environmental conditions in the NVIDIA Geforce 310M graphics card is free to toggle between integrated graphics card, ASUS U30J engine performance is very good, but the current price of 5300 yuan, or slightly higher.

Advantages:

* Extreme lightweight design college.

* Excellent heat engine efficiency.

Disadvantages:

* Prices are slightly higher graphics performance was slightly less than that expected.

• The performance of the entire entertainment applications:

ASUS U30J Although defined as a thin and light laptop(Dell Inspiron 1545 battery), but development has not adopted a processor ULV, i3 uses processors from Intel, and the implementation of NVIDIA Geforce 310M discrete graphics and integrated graphics technology transfer, as Accordingly, books section is naturally higher level of performance, then performance in the games then? Or show together.

The first is a large-scale 3D online game “Zhu Xian 2″, the game we were all open to the most advanced and found that ASUS U30J as Dell Inspiron 6000 battery can still run smooth, but slightly smaller number of frames to be in 15 or so.

In addition, we selected a Gorillaz 4″ PC version to try the game all the results are open to high-end, the resolution is also 1366×768.

Here to say that ASUS U30J battery like Dell Vostro 1400 battery and start running only on the switch as part of the video output and embedded graphics to complete the test in the game so the game itself can determine only the production of integrated graphics. Precisely because of this principle, so if you use the integrated graphics or discrete graphics game demo, DEMO mode of the game, several elements will be integrated graphics.

While in-game testing Dell XPS M1330 battery, I also broadcast two HD 1080p movies to test the Asus U30J video playback performance.

Within the game, you will find that the Asus U30J the actual process of transmission, the effects of realistic images of thin, smooth, without any effect of the video card. And the CPU occupancy rate is also lower than 20%, the overall condition is very good player.

Basic performance test:

ASUS(Asus laptop battery) U30J used HM55 i3-350 processor, chipset, hard drives for 320GB 5400RPM, while the implementation of NVIDIA Geforce 310M discrete graphics and integrated graphics switching technology, the overall performance was very good.

We see 3680 points in this entry-level position and the results are very consistent, 3D performance can only be very general, and in high definition, the basic function for smooth some of the current mainstream 3D games, but there may be some slow. But it is not 3D graphics effects are often applied, or not to ask a friend in this regard, the ASUS U30J well worth it comprises a laptop(Macbook Pro battery) computer.

The following tests run in the performance of hard disk, hard disk to 320GB ASUS(Asus Eee PC 901 battery) U30J HD Tach tests the performance is very good. Throughout the testing process, the average speed of 60.2MB / S, the frequency of explosion reached 212.0MB / S, which for some online file transfer speed is quite good.

CINEBENCH R10 for single-core and multi-state test results show that core a defiant i3-350 processor has a very good performance, single-core and dual-core 5778CB 2396CB record is the coverage of the day customers the management of speed for the processor to use.
