Battery Improvements

Battery improvements also come with Intel's TurboBoost 2.0 technology, where idle cores can be powered down to preserve battery life. The feature is also designed to deliver better performance, and certain cores can be clocked up depending on the need for speed.

The X220 laptop's performance improvements were evident in the quick Windows 7 boot time, which took 20 to 30 seconds. Mundane tasks such as antivirus did not affect the speed of other Windows applications or video running simultaneously.

Intel's integrated graphics processor in the dual-core Core i5 chip was also able to handle full high-definition graphics, which is an improvement compared to Intel's previous generation of 32-nm Core processors based on the Westmere architecture, which were released last year. The X220 came with a 12.5-inch IPS display and delivered vibrant colors without high-definition images stuttering. The old LifeBook at best could handle standard-definition video, and some laptops from last year based on the Westmere Core i3 processors often stuttered when playing full 1080p video with applications running in the background.

Intel has highlighted some additional graphics features on select laptops available through its latest Core processors, such as Quick Sync to quickly convert high-definition video into a format suitable for smartphones, and Wireless Display (Wi-Di) to wirelessly stream high-definition content from laptops to TVs.

With Sandy Bridge, Intel's core strength is the CPU, but it has also come a long way in delivering better graphics, which shows in the X220. Intel's graphics processors are good for viewing Blu-ray video and for casual gaming, but for intense gaming, users would perhaps need to buy a laptop with a separate GPU.

But on graphics Intel still lags competitor Advanced Micro Devices, which earlier this year released processors from the Fusion family, which also integrate a CPU and graphics processor on a single chip. Fusion chips integrate support for Microsoft's DirectX 11, which is a collection of APIs (application programming interfaces) to deliver more realistic images in Windows 7. Sandy Bridge chips integrate an older version of DirectX, and will catch up on DirectX 11 only next year.

Based on the improvements in Sandy Bridge, I'm tempted to upgrade my aging laptop, which now has a half-cracked screen panel. But it is even more tempting to hang on a little longer to upgrade to laptops with Core processors due next year, which will be based on Intel's latest Ivy Bridge microarchitecture. Ivy Bridge chips will be made using the 22-nm manufacturing process, which could bring more battery life and performance to laptops. Ivy Bridge laptops will have DirectX 11 support and integrate interconnect technologies such as USB 3.0 and Thunderbolt, which could help transfer HD videos from laptops to external storage devices in a matter of seconds.

As tempting as it may be, there is little reason to wait to upgrade laptops, said Dean McCarron, principal analyst at Mercury Research. Chips keep improving in performance, and battery life in laptops such as Hp Pavilion ZV6000 battery(Hp zv6000 battery), Hp Pavilion DV1000 battery(Hp dv1000 battery), Hp PF723A battery, Hp PM579A battery, Hp Pavilion DV4000 battery(Hp dv4000 battery) , Hp Pavilion ZE2000 battery(Hp ze2000 battery) will just keep getting better, so people should upgrade laptops when necessary, McCarron said.

I also had a fleeting thought on whether to ditch the laptop and switch over to a tablet. But I need a laptop for the keyboard and to run specific applications that may not run on tablets.

The X220 will become available this month starting at about US$899, Lenovo has said.
