Let us consider the two main quad core computers made by Intel and AMD. Intel was the first to launch this computer under the name Kentsfield, which is also called Core 2 Extreme quad-core QX6700, but not less than 80% faster than Conroe or Core 2 Extreme X6800.

The chips hearts of these four computers are based on the latest “core” technology micro-architecture. It is not only low power but also gives high performance. But don `t be fooled into thinking that Kentsfield is an energy-saving computer by any means whatsoever.

This computer with a 2.66 GHz chip with a 1066 front-side bus (FSB) is the ideal solution for users who require heavy or high-precision scientific calculations. It is generally used in the fields of actuarial science, digital content creation, applications for financial and technical analysis, as the OIC. The director of Intel `s digital operations group of companies, Mr. Steve Smith, argued that the quad core computer will be 58% faster for crating digital content, and for video, digital audio and photo editing.

To speak in simple terms, Kentsfield and other computers are not designed for ordinary people `s office. They are more suited for high-tech workstations and desktops. It is not wise to assume that the average customer who needs a computer for applications such as Word, PowerPoint, Internet or games, etc, go for a complex, complicated and expensive computer like this. For these purposes, there are many other types of products manufactured by Intel. Beyond that, as you guessed that this must now high-tech computer needs a lot of power and this characteristic makes it virtually unusable for people on the move. Perhaps it will take a little more research and changes before the quad core computer becomes popular as a laptop.

Intel launched the general public and a commercial version of these computers. This computer is known as the Core 2 Quad Q6600. It operates at 2.4 GHz and is currently at a price of 210 dollars. This budget quad-core computer is estimated at slightly lower thermal envelope, and will be 105 watts compared to 130 watts of Kentsfield Core 2 Extreme quad-core QX6700.

AMD’s Quad Core computer is built on a process of 65mn. They use a new technology called Silicon-on-Insulator. It allows faster transistors that have a low consumption of electricity leakage to be easily usable and this unique feature contributes greatly to reduce waste heat and electricity. For more energy conservation, each basis of this computer is authorized to operate at a speed quite different or be completely extinguished with the help of the new “Enhanced Power Now” feature. This computer is also packed with a strengthening of “Crossbar Switch” which allows users to access different parts of carrots at the same time. Other key features include the memory controller integrated with the latest architecture Direct Connect 2.0 “which allows much faster” Hyper Transport speeds. ”

Although these characteristics can extract exclamations of wonder and happiness from any geek, but the fact remains that the average PC buyer, this means the latin and Greek. Certainly much more basic computers using this technology are underway and will revolutionize the computer industry, but it will take some time before people accept this technology as an integral part of their lives. Computer makers say that within the next few years, the popularity of computers quad core will triple.

Nokia E71 is a device designed for enterprise messaging with an indication GPS for navigation, Microsoft Exchange email support, a VPN for secure communications, and voice over IP (VoIP) for making calls over a Wi-Fi Connection .

Due to become available before the end of July, the E71 is the successor of Nokia E61, but is a thin and more capable device. With its qwerty keyboard, the new model is a clear competitor for RIM BlackBerry, but heavy email users will probably find too narrow in comparison. Nevertheless, we hope that the E71 will find favour as a high-end business phone with its combination of features and battery life decent.

During testing, we found the E71 easier to use than the previous E-series devices, although there are a multitude of configuration settings which will form a management tool essential for planning services for mobilization users.

The aircraft itself is roughly the same size as the curve a BlackBerry, but is slightly heavier at 126g then it is significantly thinner - no more than 10 mm at its thickest. This means that users will not need to make a phone and e-mail device, as was necessary with some larger models BlackBerry. He also robust, thanks to its stainless steel case.

However, the E71 compact design, its qwerty keys are small and close together, even if they have a curved profile to facilitate the press. We used keyboards and tiny telephone had no difficulty typing in the e-mails and text messages using the thumb typing, but colleagues who regularly use a BlackBerry said they found the keys too small for easy use.

Nokia 2.3in 320×240 screen is easy to read in all the brightest, but the sunlight, and phone home screen has shortcuts accessible to functions such as email, calendar, Web browser, a search tool and maps. The user can customize the shortcuts that are displayed.

An interesting feature is the E71 support for a second home screen. This allows users to keep their work and personal use of the device separately. The second screen can be configured with a different background, the application shortcuts and notifications by e-mail in the main screen, and users can switch between the two, at any time.

We found that the small screen means that we pan and zoom a lot when viewing Web pages in the browser Nokia, but we have been able to satisfactorily access to many sites. The E71 is a Flash Lite, which enables users to view Flash content in web pages.

Like many other devices now, E71 supports HSDPA, which extends the bandwidth 3G data to support speeds up to 3.6Mbit / s, although this should not be considered in the practice. It also has 802.11g Wi-Fi and Bluetooth, and is a quad-band device for making mobile phone calls.

We tested the E71 using a SIM card provided by Vodafone, and we were able to get a 3G data connection virtually all the time, both inside and outside London. This gave a reasonable experience when surfing the Web, but was not as effectively as when using Wi-Fi

The use of Wi-Fi on the E71 is an improvement over the E61. We found we could search for available networks and select one, simply enter the passcode to access. The E71 remembers these parameters and then automatically connect to access points that he knows.

As a messaging device, the E71 is compatible with Microsoft’s ActiveSync protocol for the exchange of messaging systems and its own Nokia Intellisync middleware, which can link with Exchange, IBM Lotus Domino or Novell GroupWise. These suites can also be used to implement management settings, distance and lock or erase the handset. Email support also covers POP3 mail accounts, with a wizard that automates a large part of the configuration.

A pure security feature is that the user can define a word or phrase which locks the device when it is sent to him as an SMS text message. This allows the E71 and a memory card in it to be locked remotely if it is lost or stolen, and requires a PIN to unlock it. The phone responds with a message to let you know that the remote lock has been successful.

For navigation, the E71 supports assisted GPS (A-GPS), which increases the satellite signals with information about the location of the cellular network. Nokia Maps application allows users to get a fix on their location, but we found the device can take up to 20 minutes to get an initial position, which can be frustrating. Nokia cards can also search for equipment and give walking or driving instructions to navigate. It can give voice instructions, but users must pay for this service.

Nokia also includes a VoIP customer with the E71 which allows users to make and receive calls over Wi-Fi This function uses the Session Initiation Protocol (SIP), commonly used by corporate mail servers and IP PBX equipment. We tested with an Internet-based service provider SIP, and found the call quality comparable to that using the cellular network.

SIP configuration requires a lot of information to be provided, which means that most workers are unlikely to be able to establish themselves. It can be set to automatically switch to VoIP calls if it is connected to an authorized Wi-Fi access point, which would allow companies to save money on mobile call ensuring that calls are routed through the company PBX when users are on the spot.

Nokia Mobile VPN IPSec is a client-compatible with Check Point and Cisco gateways, which can be managed by a server. Other applications included with the E71 include Quickoffice, which is compatible with Microsoft Word, Excel and PowerPoint (in the formats used for Office 2003). It also has an archive tool, a PDF reader Adobe and a tool for printing.

Although Nokia is a thin line combined, it comes with a decent size 1500mAh battery that seems to offer a long battery life. During tests, we made frequent use of 3G, Wi-Fi and GPS functions, although it is still the E71 lasted about a week between charges. The charger for the handset is also very low - the size of a plug - which makes it easier to transport on journeys.

The E71 supports Micro SD flash memory cards for storing up to a maximum of 8 GB size. The slot is left of the camera, next to the screen, and is protected by a blanket rubbery. Alongside this is a mini-USB connector to link the E71 to a PC for synchronization using Nokia PC Suite. The E71 is also a built-in 3.2 megapixel camera with flash.

Asus Eee PC 901
Windows XP Home Edition SP2; 1.6GHz Intel Atom; 1024MB DDR2 SDRAM 400MHz; 128MB Mobile Intel 945 Express; 12GB Phison Solid-State Drive.

We were impressed by the PC Asus Eee line from the first 7-inch model in the autumn of 2007, and it seems as if every time we turn around, there is a new version to hit store. This 9-inch version, the EEA PC 901, is simple months after the substantially similar Eee PC 900, by adding a few features list, another $ 50 for the price and, more particularly, the new Intel-based NETBOOK Atom CPU.

We were surprised to find that Intel-based model atom finish behind the Celeron-based Eee PC 900, but $ 599 Eee PC 901 is still the best version of this laptop inexpensive yet, thanks to its fantastic autonomy the battery and design tweaks - including better touch pad and mouse buttons new quick-launch buttons. Like the EEA PC 900, it offers a choice of Windows XP and Linux operating systems have a valid reason for 12GB (20 GB in the Linux version) solid-state disk drive of the space.

Although the EEA was the first consumer NETBOOK on the market, competition has not been idle. Hewlett-Packard now has the excellent 2133 Mini-Note, Dell is working on a NETBOOK style laptop, MSI and often delayed Wind gaining buzz as a PC EEE-killer. Now, priced at $ 600, EEA PC suddenly is in the same category as the budget include laptops, which offer faster processors and much larger hard disks, but not the portability and the battery life of the EEA. To keep pace with competition, Asus will have to double on price or performance in future versions of the EEA PC, or risk being squeezed out of a market almost single-handedly created.

The new Eee PC is slightly larger than the first 9-inch version, the EEA PC 900, and our review had a glass black finish, rather than white, plastic pearlized search for three previous Eee PC we reviewed. The EEA PC is still incredibly small, roughly the size of a paperback trade, a size which, until recently, was only available in high-priced ultra-portable or even more expensive UMPCs.

The touchpad now has two mouse buttons, as opposed to the rocker-type left / right move on previous models of computers Eee. The touchpad also contends the gesture control (similar to the MacBook Pro and Air) introduced for the first time on the EEA PC 900. Images can be pinched and unpinched with the thumb and forefinger to zoom in and out, and two fingers can be used to scroll up and down Web pages.

The keyboard, with its small size UMPC key is still difficult to use for periods spent, but we do like the new line of rapid launch buttons that sit above the keyboard to turn off the display, scroll different screen resolutions, the transition of power between modes of economy and the launch of Skype.

The display is the same 8.9-inch on the EEA 900, with a decent 1024×600 pixels native resolution, which is much easier to use than the 800×480 pixels resolution of the original 7-inch Eee PC.

The SD card slot offers a good opportunity to strengthen the hard drive space, so you can insert your own flash memory, adding the construction 12GB (4 Go east on the motherboard, and there is a chip 8 GB SSD as part of a group User accessible on the merits of the system. It is still not a lot of space for files and applications (and less than 20 GB per elsewhere that the Linux version identical supplies - your premium to skip the cost of a license XP).

The EEA PC 901 is the first laptop, we have our hands on the new Intel processor Atom, specially designed for small, low-power NETBOOK style devices such as this. While the pre-hype has Atom CPU running faster, cooler, using less energy, and even pick up your dry cleaning, the reality is somewhat less impressive. The 1.6GHz Atom is actually a little slower than Eee PC 900, which has the most Celeron M 900 MHz CPU, and much slower in our multitasking test. On the other hand, the atom-powered Eee was faster than the old 7 inches Eee PC (which has the same Celeron) and much faster than HP VIA-powered Mini-Note 2133. We also saw significantly improved scores battery, and low energy consumption is a major outlets for Atom-powered products. Intel is already expected to work on a new generation of dual-core chips Atom May improve performance while multitasking.

The Asus Eee PC 901 has operated for 5 hours and 15 minutes playing our video battery drain test, which is one of the best scores battery life, we have seen a laptop in a category. It is thanks largely to the EEA energy efficient, using the new Intel processor Atom and a solid-state disk drive. The system will also automatically underclock the CPU while running on battery power (although you can force it to run in high performance through a mode of application system tray).

Asus covers its laptops with one standard, one year parts and labor warranty, and offers online on the Web and assistance toll-free telephone number. The company Web site includes technical assistance should the driver downloads and a brief FAQ, but lacks useful features such as user forums or the opportunity to interact in real time with a technician.

The good: Much-improved battery life; new mouse and quick-launch buttons; still highly portable and reasonably priced.

The bad: New Atom CPU is slower than previous Celeron Eee PC, slightly bigger than the Eee 900; price is creeping up to the full-size laptop range.

The bottom line: The long-awaited Asus Eee PC 901 is the best version of this inexpensive Netbook yet, but it’s facing increased competition from the likes of HP, Dell, and MSI.

After a delay of more than a month because of problems related to the integration of graphics and wireless licenses, Intel will launch the platform Centrino 2 during a demonstration in San Francisco. A number of PC vendors, including Hewlett-Packard, Lenovo, Toshiba and Fujitsu, are preparing a series of new notebooks to coincide with the release of Centrino 2, formerly code-named Montevina.

While Intel hopes to take its share back-to-school retail with Centrino 2, the new mobile platform is also an important launching the business in IT services are beginning to explore new laptops, so ‘buy and sellers try to distinguish their notebooks of the competition.

At its debut Centrino 2 July 14, only some of the new chip sets and processors will be available at launch, which will delay the lowest range that rely on Intel own integrated graphics card. Laptop computers using discrete graphics from ATI or NVIDIA will be available in due course. A spokesman for Intel said that all products are shipping in volume and all processors and chip sets will be available by early August.

The launch of Centrino 2 is also at a time when consumers and buyers are companies yearning for more mobility when it comes to computers. Intel This is the fifth version of its mobile platform and it comes at a time when notebook shipments and revenues continue to exceed desktops, which makes each new mobile platform more important than the last .

Advanced Micro Devices has also launched a new mobile platform called Puma, which beat Intel in the market thanks to the delay. While Intel and AMD are pursuing consumers, who are currently driving the PC market, Centrino is more oriented buyers of large companies, while Puma is designed for small and medium-sized companies looking for a little Cheaper notebook.

In addition to new processors, graphics and support for both Wi-Fi and WiMax, the new platform is likely to offer new security and management functions through the company vPro technology. (The spokesman for Intel declined to provide details on updates vPro before the official launch.)

It is already well known on 2 and Intel Centrino thus providing the platform to encourage buyers. Firstly, Centrino 2 is the first mobile platform to use the company to 45 nanometers Penryn microprocessors, and reports indicate that chips have clock speeds ranging from 2.4 GHz low-power models at 2.8 GHz or better for the world’s largest processors. The platform will also support DDR3 (double data rate 3) memory.

Deployment Intel dual-core processors first and follow that with quad-core chips later.

The transition from 65 nm to 45 nm-Intel chips can provide a platform should not only increase battery life in notebooks, but also means that this new generation will be more energy efficient and not as hot as the previous generation of laptops. Indeed, a blog Intel has revealed that many new notebook processor will run at 25 watts compared to the old 35-watt models.

The new Centrino platform will also enable OEMs to get more creative with their notebook designs and give them another opportunity to add features and different technologies.

“It is an opportunity for Intel to sell both the enterprise and consumer customers, but the launch of Centrino has a lot of what the business guys want, as vPro,” said John Spooner, an analyst at Technology Business Research. “This launch is a nod to the business side of the house and this is a great opportunity to refresh for OEMs and their business notebook lines. It is also an opportunity to show new innovations. ”

For example, HP announced a number of new laptops in June that are likely to use the Centrino platform 2. Among these models is the EliteBook HP, with a magnesium alloy, 14.1-inch screen and reported 15 hours of battery, which offers robust feature in a book of 4.7 cases much lighter than others injured semirugged blocks Notebook or on the market.

On the networking side of the platform, Intel offers a technology called Eco Peak, which will support technology Wi-Fi, including the most recent 802.11 Draft N standard, as WiMAX. For now, Wi-Fi is more important than WiMax networks are still being developed in the USA, although the technology is beginning to gain presence overseas, notably in Asia.

For Intel, the launch of Centrino 2 is the last major announcement before it unveils its new microarchitecture Nehalem its Developer Forum in San Francisco in August. The Nehalem chip will not appear in the company of mobile platform, code-named Calpella, at least until 2009.

SE-Explorer is a simple dual-pane file manager that offers tabs for folder browsing as well as several built-in viewers including XML structure view, image browsing, integrated audio playback with playlist support, hex view and more. The program also includes a file search feature that is similar to the old file search under Windows XP.
