A New Breakthrough

The Intel Centrino 2 processor technology family represents the most significant advancement in mobility since the original launch of Intel Centrino processor technology in 2003. Essentially a marketing term, Centrino 2 is used to describe a raft of new technologies including: a handful of new Core 2 Duo processors; a new chipset with a faster front-side bus; a new graphics solution with support for high-definition content and switchable graphics; and updated wireless and wired connectivity. With laptops based on this new technology, you'll experience a breakthrough on all five vectors of mobility:

These computers are equipped to handle everything from robust business to masterful media—and everything in between. Intel Centrino 2 processor technology also includes advancements designed to enhance the mobility experience for both consumer and business users. Both feature a 1066 MHz FSB, high clock speeds, faster DDR2 (800 MHz) compared to the prior generation, as well as DDR3 support (up to 1066 MHz).

So what does this mean for you? In this article, we'll describe the new features and benefits of this advanced technology.

New processors: The processors launching with the new platform are built on the same 45nm Penryn architecture that debuted earlier this year, though the new chips now support the faster 1066MHz front-side bus.

Three of the processors are part of a new class of energy-efficient CPUs designed to enhance battery life, and they are designated with a part number "Pxxx" (think P for "power optimized"). These Penryn chips support a range of power-saving capabilities, from selectively shutting down unused parts of the chip, to a deeper-sleep mode, which allows the laptop to use a negligible amount of power when in standby mode. The energy-efficient CPUs have the added advantage of staying cooler than their more power-hungry counterparts, a development that should bring about even smaller, thinner laptops.

The remaining processors (part number "Txxx" and "Xxxx") prioritize performance. All six processors are priced as follows:

Enhanced network connections: For wireless modules, the platform will include Wi-Fi support with the option of using a WiMax add-on card (both options support the 802.11n standard). With the new wireless add-on card, you'll be able to roam up to twice as far as you could with the company's previous Wi-Fi chip. Intel is heavily marketing WiMax as the high-speed wireless broadband service of the future for laptops and smaller computing gadgets.

On the wired side, support for high-speed Gigabit Ethernet—a feature that's likely to appeal to business users—is standard with Centrino 2.

Faster overall performance: The new Mobile Intel 45 Express chipset increases the frequency of the front-side bus to 1,066MHz, which helps all the components of the system communicate more quickly. It also supports DDR3 memory, which has a higher peak throughput than previous memory technologies. Intel is always reluctant to quantify performance improvements, but company representatives have promised "dramatic" performance gains.

Personal Users

On top of these native components, the Intel Centrino 2 processor technology family adds additional features for consumers. For starters, the system comes equipped with Blu-ray logo-capable playback so you can enjoy your HD movies on-the-go. Another big development available on Intel Centrino 2-based laptops is switchable graphics, which is supported by a new 45 chipset. Intel claims that the mobile GM45 express chipset (pictured below) offers 70% greater performance than its predecessor.

Switchable graphics provides both integrated and discrete graphics on a single notebook, enabling users to easily switch between the two options. This feature, which can be either user-controlled or automatic, delivers greater 3-D performance when needed while providing the option for greater power savings.

Business Users

For businesses, Intel Centrino 2 with vPro technology features built-in maintenance capabilities and enhanced security options that readily integrate with software management solutions. Designed to lower IT costs and improve IT efficiency, Intel Centrino 2 with vPro technology offers a unified approach for administering and protecting computers throughout your organization. With the latest IT management consoles, you can monitor and maintain your laptops over a wired or secure wireless network. Plus, you'll have the ability to deploy patches and updates from anywhere, even if the client computer is powered off. This is increasingly important as companies replace desktops with laptops and need to remotely diagnose, update and repair systems over a wireless network. 

Conclusion

Overall, Centrino 2 has all the hallmarks of a sure-fire hit. Every component of the platform has seen at least modest enhancements designed to increase performance, decrease power consumption, and add functionality. And while it's too early to speak in general terms, our preliminary findings seem to back up at least some of Intel's claims.
