Intel's description of "netbook" is: "Netbook is a wireless Internet device with Intel Atom processor, which has the functions of surfing the Internet, sending and receiving emails, instant messaging (IM) and so on, and can smoothly play streaming media and music."
A netbook is a notebook computer with incomplete functions. Netbooks can be less than 10 inch and weigh less than 1.5kg, which is cheap. Netbooks can have a series of entertainment functions such as instant chatting, surfing the Internet, sending emails, watching videos and basic online games on the basis of energy saving.
The standard configuration of the first generation netbooks is: (such as the early ASUS Eee PC)
CPU (Central Processing Unit): VIA's Nano (physical core frequency is 800MHz) or equivalent processor.
Memory: 5 12MB
GPU (graphics processor or graphics card): Integrated graphics card
Hard disk: 20~40GB SSD or 40~60GB traditional mechanical hard disk.
Network card: 10/ 100M
Wireless network card: built-in 802. 1 1b/g wireless network card.
The standard configuration of the second generation netbook is:
(At present, all the second-generation netbooks are sold on the market (in early 2009). )
CPU (Central Processing Unit): Intel Atom? Processor Diamondville Atom N270 (with one physical core, because of Intel HT Hyper-threading technology, it simulates two logical cores, the main frequency is 1.6GHz, the front-end bus is 533 MHz, and the secondary cache is 45 nm. Manufacturing process is 5 12KB).
Memory: 1GB DDR2 667MHZ supports up to 2GB.
GPU (graphics processor or graphics card): Intel GMA 950 integrated graphics card.
Memory: * * Maximum enjoyment 128M (depending on main memory capacity).
Chipset (motherboard): Intel 945GSE+ICH7-M
Network card: 10/ 100M
Wireless network card: built-in 802. 1 1b/g wireless network card.
Hard disk: 60~ 160GB traditional mechanical hard disk, with a maximum support of 320GB.
Camera: 65438+300,000 pixel camera
Support VGA video output
The high-end version also has Bluetooth module, security keyhole, DC input interface, support for 2.5G or even 3G Internet access and so on.
Note: Some netbooks may encounter the problem that they cannot play 720P HD movies smoothly due to poor performance. In fact, it can be played smoothly with the latest version of Kmplayer. Because Kmplayer has "extreme speed mode", it can speed up the playback speed on the premise of ensuring the image quality, and it is worth using.
In the past, the size of netbooks was generally 7 inches (first generation), but now it is generally 8.9 and 10.2 inches (second generation). At present, there are a few 12 inch netbooks, the weight of which is below 1.5 kg, and most of them are around 1.0- 1.2 kg. Most keyboards are not ergonomic full-size keyboards. Only a few new 10 inch netbooks are equipped with full-size keyboards, which is one of its shortcomings: adults will have a certain adaptation period when using them, while primary and secondary school students will be more relaxed when using them.
"Netbook" is a term coined by Intel at the Taiwan Province International Computer Show last week. Before that, it didn't have a Chinese name, so everyone called it "netbook". Market positioning is: first, business people who need a second or even a third laptop; Second, teenagers, primary school students and other groups that need to access the Internet are convenient for learning and application; There is a third kind of people who are special professionals, such as journalists and geological prospectors. People who often need to travel, and even housewives who like to buy stocks online, are also the target groups of "easy PC"; The fourth kind is a fashion family, who likes to travel and enjoy novelty.
Intel has a similar positioning for "netbooks". A related person of the company told reporters that "netbooks" are suitable for people who want to own a second or even a third computing device, as well as students or users who are first exposed to the Internet.
At the same time, Intel believes that the use of "netbook" is different from that of traditional notebook computers: unlike notebook computers (or EPCBOOK), "netbook" mainly focuses on "consumption" content, and can support online friends, surfing the Internet, listening to music, watching photos, watching streaming media, instant chatting, sending and receiving emails, basic online games and so on. Notebook computer (or PC) can install advanced and complicated software, download, store and play CD/DVD, conduct video conference, open and edit large files, multitask and experience more games that need to be installed.
Simply put, "netbook" is a notebook computer with incomplete functions, "surfing the Internet" is the core application, and Wi-Fi wireless broadband is the core function. However, it should be noted that the domestic Wi-Fi wireless broadband access environment is not perfect. If you don't have Wi-Fi service around you, a netbook can't do anything.
It is precisely because of the maturity of Wi-Fi wireless broadband that netbooks are restricted, so the first stop for ASUS to launch Easy PC is in the American market with developed wireless network, and the promotion speed of Easy PC in China market is always "one beat behind". [Edit this paragraph] Fully interpret the parameters and performance of the matched chipset and graphics card.
Atom's 945GC chipset is ridiculous. The core area and power consumption of the North-South Bridge chipset are much larger than the Atom processor itself. There is really an artistic conception of "a small horse-drawn cart". This chipset is not designed for the very energy-saving Atom, but Intel temporarily pulls out the old chipset as this important task. The power consumption of this chipset is about 25W, while the typical Atom is only 2W…… ... ...
1, the first generation of Atom series notebooks, such as the EPC of ASUS, did have a 945GC chipset. At that time, Intel didn't develop a suitable chipset for Atom. As a result, it could only match the existing notebook chipset instead of UMPC, so the actual effect was high power consumption, reaching about 25W.
However, most Atom notebooks on the market now use i945GSE+ICH7M chipset, with a power consumption of 5.5W(4W is the north bridge, 1.5W is the south bridge), which is a very reasonable match for Atom.
2. The biggest difference between streamlined Atom chipset (945GSE) and 945GC is GMA950 graphics card. Although the model is GMA950, the graphics card frequency of 945GC is the standard 400MHz, while that of 945GSE is 133MHz. Intel did this to reduce power consumption, but obviously low power consumption brought about a significant decline in performance.
So it is impossible to run some popular 3D games smoothly with the popular Atom notebook (of course, Warcraft and CS can still cope). Because the reduction of frequency brings about 50% performance degradation. However, the video can still be played, and 720P HD H.264 can be played smoothly. Although the CPU utilization rate is high, the video encoded by 720 VC- 1 is still not smooth due to the driving problem of GMA series graphics cards.
3. Was the previous 945GC really that strong? After further exploration, we found some problems with the GMA950 graphics card: Now let's look at the graphic chip GMA 950: this is the IGP used by Intel Corporation in the i945 chipset. DirectX 9-compatible and Aero-supporting applications using Core Duo processors are common in portable computers.
Intel uses i945G graphics chip on desktop, and its core frequency is 400MHz, but the frequency is reduced to 250MHz on portable computers and to 166MHz on some ultra-portable notebooks. This time Atom is matched with GMA950 of 133Mhz, but the streamlining degree is not as serious as everyone thinks, and it can be regarded as a balanced design.
Intel 945GM ——250MHz
Intel 943GML ——250MHz
Intel 940gml-166mhz
Intel 940gms-133mhz
4. From the comprehensive evaluation on the Internet, it can be seen that XP and vista have little difference in the performance of notebook computers with independent graphics cards, while the performance of single-core notebook computers with GMA950 has dropped significantly. Dual-core processors are of great significance for running vista on a machine integrated with a graphics card such as GMA950: one core helps the graphics card and the other handles user tasks.
This has a lot to do with the characteristics of Intel integrated graphics cards. GMA950 originated from GMA900 series, and still supports version 2.0 pixel shader, lacking hardware T&: L and vertex shader functions, vertex rendering and geometric transformation, and the light and shadow part still needs CPU calculation. But in fact, nVIDIA GeForce6 1x0, ATi RS48x and other integrated graphics chips do not actually integrate vertex shaders and T &；; L engine, its triangle and vertex operations in the process of 3D rendering depend on CPU to help speed up, but the dependence is lower than GMA950. The implication is that the 3D performance of the dual-thread or multi-thread Atom netbook with hyper-threading technology will be far superior to that of the single-core Core 2 Celeron processor. [Edit this paragraph] The difference between a netbook and a notebook.
appear
First of all, from the appearance, although netbooks [1] look like ordinary notebooks, their screen sizes will be different. The screen of most netbooks is 7- 10.2 inch, and ordinary notebooks are basically above 10.2 inch. In addition, netbooks emphasize portability, and most of them are small, light and colorful.
Configuration and performance
In terms of configuration and performance, netbooks basically use Intel Atom processors, emphasizing low energy consumption and long battery life. The performance is mainly to meet the basic internet needs, and the multimedia performance of ordinary notebook computers is stronger. In addition, netbooks emphasize the ability of wireless internet access, and the size of hard disk is not as good as that of ordinary notebook.
use
Netbooks are mainly online, and can support online friends, surfing the Internet, listening to music, watching photos, watching streaming media, instant chatting, sending and receiving emails, basic online games and so on.
Ordinary notebook computers can install advanced and complicated software, download, store and play CDs/DVDs, conduct video conferences, open and edit large files, multitask and experience more games that need to be installed.
price
At present, the price of netbooks ranges from 1500-3999 yuan, while the price of traditional notebooks ranges from 3000 yuan to tens of thousands of yuan according to the positioning of manufacturers and the needs of users.
The difference between netbook and UMPC
Many people will confuse netbooks with UMPC, which is quite different from UMPC (ultra-portable personal mobile device) and MID (handheld mobile device). Compared with mainstream notebook computers, netbooks are smaller, cheaper and less functional. UMPC is also a concept put forward by Intel. Officials believe that UMPC can only be called if it meets many conditions such as "7-inch or smaller display screen", "built-in touchpad" and "minimum resolution of 800×480". As far as the current market situation is concerned, the size of UMPC is generally 5.6-7 inches, with functions such as rotating screen or touch screen, and the price is much higher than that of netbooks. MID is smaller than UMPC, so it is more suitable to put in your pocket. It is undeniable that netbooks find the best balance between portability and cost performance.
It is worth noting that netbook computers are shaking the monopoly position of Microsoft operating system, and the price of Microsoft Windows operating system is still too high for PC manufacturers who want to launch the cheapest netbook. Jenny, a Taipei analyst at CLSA Limited? Jenny Lai estimates that installing Linux on a computer costs only $5, while XP costs about $ 40-50 and Vista costs $65,438+000.
At present, about 30% of the netbooks on the market use Linux operating system. In China, I was glad to hear that the sales of Linux netbooks launched by Intel and Great Wall Computer soared. There is no denying that Linux and netbooks share many characteristics. With the participation of more enterprises, netbooks will surely make a breakthrough in functional characteristics and cost performance, and become a hot product in the mobile era.
The word "netbook" comes from the British small computer manufacturer Psion Teklogix, which launched a small notebook called Psion netBook between notebook and PDA a few years ago and registered the trademark of "netbook" in the Copyright and Trademark Office. Psion first used the trademark term netbook in199665438+February, and at the end of 2008, Psion decided to protect the "netbook". Some netbook enthusiasts' websites have received its discontinuation ("Stop &; Stop ") notice, asking to delete the term" netbook ". It gave a three-month deadline and asked to delete the content before March 2009, otherwise it would be prosecuted.
WhoIS.com database shows that Netbook.com's domain name was created on August 25th, 1994, and was bought by Intel on September 29th, 2008. Registration information has been changed to Intel related information.
In addition, the recent "cottage" culture and "cottage notebook" have also become the strongest competitiveness of many brands of netbooks. The framework scheme led by VIA in Taiwan Province Province, China will make netbook products richer, faster and more personalized.
Netbook is a portable low-profile notebook computer, its specific function is to facilitate Internet access, and it needs to be equipped with 3G Internet access equipment.
The disadvantage is that the screen is too small and it takes a lot of effort to read words. Some websites have noticed this problem, such as epcbook.cn, which has made a large font URL for netbook users. Baidu search with large font is estimated to provide many netbook users with different feelings.
In mid-2009, among the two pillars supporting the development of IT industry,
One is a netbook.
The other is the grave digger of Windows Vista-Windows 7 [edit this paragraph] netbook has eaten up 12% notebook share this year.
In 2008, the sales volume of China netbook market was 900,000 units, but in 2009, the sales volume of China netbook market will reach 2.02 million units, up by 124.4% year-on-year. Under the background that all other computer products are facing a decline in sales, netbooks have become a unique commodity that is completely unaffected by the crisis. "It may occupy more than one-sixth of the notebook market this year." Guo Chang, an analyst with the General Product Research Department of Jishi Information, said.
15 In April, China Mobile and 17 PC giants launched 29 netbooks, including Lenovo, Dell, Hewlett-Packard and Haier. According to reports, the cooperation with PC manufacturers is divided into two types: deep cooperation and general cooperation, and then the subsidy amount is determined according to the promotion intensity. The highest is 2 100 yuan/set, followed by 1500 yuan/set, and the most common cooperation is 900 yuan/set. However, the relevant PC manufacturers have to complete the sales task. For example, in order to get a subsidy of 2 100 yuan, PC manufacturers have to sell 90,000 units every quarter. At present, six manufacturers have become the highest-level partners of China Mobile Netbooks, namely Lenovo, Founder, Tongfang, Haier, Hewlett-Packard and Dell. Dell also held a TD netbook conference on April 16, and said that there will be more products to support China Mobile. According to industry insiders, the quarterly sales volume of 90,000 units is not a problem.
Almost at the same time, on April 16, China Telecom also unveiled more than 20 netbooks, and many PC manufacturers such as Lenovo, Founder, Haier, BenQ, Hewlett-Packard, Asus, etc. 10 cheered. Many manufacturers confirmed that China Unicom's netbook is also being customized, and it is expected to be officially launched when 3G numbers are released. In this way, we seem to have entered a brand-new netbook era in an instant.
China Mobile G3 notebook computer is the first time for China Mobile to cooperate with various computer manufacturers in order to meet the 3G era. Built-in TD wireless Internet module, the terminal support rate can reach up to 2.8MB/ s, and it can switch to the edge of 2G/GSM. At the same time, the Internet access fee is tied with the existing China mobile number to realize unified invoices and bills. At present, merchants in Beijing only choose Gome for spot sale. At present, HP, Haier and Dell are customized brands, and China Mobile will give consumers a maximum subsidy of 2 100 yuan for phone calls and Internet access fees.
Portable mobile computers are small in size and low in price.
Netbook is an ultra-portable mobile PC with Internet as its main appeal. Its size is mostly below 10 inch, and it is mostly used for mobile internet access for business trips, tourism and even public transportation. Netbooks are the biggest selling point because of their small size and low price. In the current financial crisis, they have gradually become the choice of many consumers when buying a second notebook.
According to Gome professionals, G3 netbook is a notebook computer specially used for surfing the Internet. The main target groups are customers who always pay attention to information, such as stock investors, journalists, and all kinds of customers who have high requirements for timeliness of online information, providing convenient and fast communication channels for all groups. G3 notebook can switch freely between 3G and 2G networks. When customers access the Internet wirelessly in areas with good 3G network coverage, the rate can reach 2.8Mbps, and when switching to 2G network, the rate can reach 460kbps, which is very fast. Ordinary netbooks are often used as large-screen MP5, and how to surf the Internet outdoors has become the primary consideration for everyone. In order to surf the Internet outdoors, people usually buy wireless network cards or connect through external network terminals, but its speed and inconvenience make people helpless. The launch of G3 netbook can completely solve the speed problem.
Wireless internet access, no roaming charges, national unified price.
At present, several G3 netbooks have been well received by consumers as soon as they are listed in Gome stores. In addition to the preferential price, the mobile G3 notebook realizes the national unified tariff. No matter where customers use G3 notebook to surf the Internet in China, the tariff is the same, and no additional roaming charges will be generated. In terms of Internet access fees, there are currently three traffic packages: 50, 100 and 200 yuan, and the monthly excess is only 0.0 1 yuan /KB. Roughly calculated, you only need to pay about 100 yuan a month, and you can enjoy the service of sending and receiving emails every day and chatting with instant messaging software. At the same time, there is no roaming fee for "G3 Notebook" wireless Internet access, and the price is unified throughout the country through "G3 Notebook" wireless Internet access. For consumers who are ready to buy notebooks online, G3 notebooks undoubtedly bring an excellent opportunity to start.
G3 notebook and 3G charges
G3 notebook is a new notebook jointly launched by China Mobile and several well-known manufacturers. It has built-in 3G communication module of China Mobile and installed various practical office and entertainment software. Customers can surf the Internet wirelessly anytime and anywhere through G3 e-commerce software pre-installed in G3 online notebook, which is very convenient for obtaining information, entertainment or mobile office.
At the same time, the sales price and subsidy amount of G3 notebooks are exciting. Let's work out an account. In the past, it cost about 3,500 yuan to buy a traditional notebook computer, and it cost about 1000 yuan to buy a 3G wireless network card. Now you can own a G3 notebook with a built-in 3G wireless Internet access module for only about 3,500 yuan, and you can get a maximum of 2 1 0,000 yuan for phone calls and internet access, which is equivalent to the current 1, about 400 yuan. For consumers who are ready to buy notebooks online, G3 notebooks undoubtedly bring an excellent opportunity to start.
"The Internet access fee of G3 notebook can be directly deducted from the phone bill of GSM number bound by customers. I believe this setting will provide more convenience for customers." A related person from China Mobile Guangdong Company said that after purchasing G3 notebooks, GSM brand customers can use the built-in e-banking client to log in to China Mobile's G3 Notebook Business Website with e-banking for free, select the tariff mode, and pay by binding with the customer's current number, so as to realize the function of using GSM phone bill to pay the laptop internet fee. At the same time, the source said that G3 notebooks have a unified national tariff. No matter where customers use G3 laptops to surf the Internet in China, the charges are the same, and there will be no additional roaming charges. In terms of Internet access fees, four traffic packages of 50, 100, 200 and 300 have been launched, and the monthly excess is only 0.0 1 yuan /KB. Roughly calculated, you only need to pay about 100 yuan a month, and you can enjoy the service of sending and receiving emails every day and chatting with instant messaging software.
It is understood that G3 notebooks can switch freely between 3G and 2G networks. When customers access the Internet wirelessly in areas with good 3G network coverage, the rate can reach 2.8Mbps, and when switching to 2G network, the rate can reach 460kbps. This setting undoubtedly gives consumers who are still hesitating a reassurance. "In 2003, when China Mobile first started to pre-store phone bills to send mobile phones, I felt very favorable. I bought a customized mobile phone at that time. " Mr. Xu, a customer of Global Connect, said: "Now I have started to customize my notebook. Too favorable, too comprehensive. Of course, I have to get one right away! "
With the successful experience in the field of mobile phones, it is believed that China Mobile will create a new round of online notebook consumption boom through the strategy of G3 notebook. China Mobile Guangdong Branch said that taking Guangzhou as an example, young consumers with college students as the main body have a high spending power, and the fashionable positioning and preferential price of G3 notebooks are in line with the college students' market, which will soon form a consumption trend on campus. Starting from 12, G3 notebooks can be bought in the designated "Communication 100" service halls in Guangzhou and Shenzhen, and will be sold in major supermarkets such as Gome, Suning and Computer City in the next stage. Consumers will be able to easily experience wireless Internet access in the 3G era.
