Get with a Sandy Bridge laptop

Laptops with Intel's new Core i3, i5 and i7 processors have started shipping to consumers, and include features that bring longer battery life and new levels of graphics and application performance to PCs.

Many performance improvements are enabled by Intel's latest chips, which integrate a graphics processor and CPU in a single chip. The laptops also preserve life of battery like Fujitsu FPCBP80 Battery, Fujitsu FPCBP77 Battery, Fujitsu FPCBP68 Battery, Fujitsu FPCBP63 Battery, Fujitsu FPCBP95 Battery, Fujitsu LifeBook C1320 battery, Fujitsu FPCBP115 Battery, Fujitsu LifeBook C1321 battery, Fujitsu FPCBP152 battery, Fujitsu FPCBP130 battery through chip-level improvements and technologies such as solid-state drives (SSDs), which draw less power than hard drives.

Intel started shipping Sandy Bridge processors for laptops in late February, and laptops are slowly trickling out to replace models with older Intel chips. PC makers including Lenovo, Dell, Hewlett-Packard and Toshiba have already announced laptops based on new Core i3, i5 and i7 processors, with prices starting at US$599.

I was awaiting the release of Sandy Bridge laptops to upgrade my aging Fujitsu LifeBook P8010, which I bought in mid-2008 for a bargain price of $710 off the PC maker's eBay auction store. The LifeBook was powered by the same dual-core Core 2 Duo microprocessor included in the original MacBook Air, and was made using the older 65-nanometer manufacturing process. Intel's latest Core chips are made using the latest 32-nm process, which has improved chip performance while reducing leakage, bringing longer battery life to laptops.

The results were visible in a preproduction unit of Lenovo's upcoming ThinkPad X220 ultraportable laptop, which was loaned by the company for evaluation. The laptop's mundane black-box design was reminiscent of old ThinkPad models, but the machine showed significant graphics, performance and battery-life improvements compared to laptops based on older Intel chips.

Lenovo says the X220 can clock 23 hours of battery life with a nine-cell battery and a spare external battery pack. Power consumption depends on laptop configuration, and the X220's runtime measured anywhere between seven and eight-and-a-half hours on a six-cell battery with a dimly lit screen. That compares favorably to five to six hours of battery life on my trusty old Fujitsu P8010, with a screen even dimmer.

Dell and Toshiba have also touted long battery life as one of the major improvements with their new Sandy Bridge laptops. Dell's Inspiron 15R laptop, which includes a 15-inch screen, provides about 13 hours of battery life with a nine-cell battery. Toshiba said its Tecra R840 laptop, which includes a 14-inch screen, could deliver battery life of up to 11 hours when configured with an SSD.

Some chip-level improvements have also helped improve battery life. Intel for the first time has roped in the graphics processor and CPU on one chip, and one way for chip makers to improve battery life is by pulling in more components inside a single chip. The laptop also consumed less power in sleep mode and did a better job at idling components than my three-year-old Fujitsu.
