It's no surprise that Windows 7 is getting good reviews and praise as the operating system is proving itself to be a rock solid platform. It seems as the news is only getting better as Microsoft and Intel showed off how Windows 7 when paired up with Intel's new processor line will increase battery life for laptops, according to

The two companies worked together to help develop technologies that will allow for sustained performance while improving battery life in the next generation of Intel processors.

"The dramatic leap in battery life appears tied to a technology known as Windows 7 timer coalescing, a technical term for minimizing the time in which the processor enters a high-performance, full-power state. In the past, different applications have called for the processor's performance at varying times, requiring the CPU to ramp up performance and then down again, frequently. By synchronizing the timers, Intel managed to boost battery life tremendously. Intel executives said they also expect to take more advantage of this technology in future platforms."

The bottom line is that when comparing two identical laptops one with Windows XP SP2, the other with Windows 7, the Windows 7 machine was able to last 1.4 hours longer than the XP machine while playing a DVD. This was based on current products and did not include Intel's upcoming i5/i7 processors line.

The extended battery life will benefit the consumers and Intel claims that its upcoming line of i5/i7 processors will be able to expand on the battery life improvements by implementing the new technology. AMD has also stated that they will offer the new technology too in their processors in the future.
