Core I7 Laptops Make The Others Bite The Dust

Sept. 25, 2009 - PRLog -- Utilizing the Clarksfield quad core CPUs with 45nm technology you will see performance like never before and in early 2010 32nm dual core CPUs will become available for new Core i7 laptops.

Core i7 laptops will ship with 3 versions of the CPU:

   * 1.6 GHz i7-720QM
   * 1.73 GHz i7-820QM
   * 2.0 GHz i7-920XM

The Core i7 CPUs utilize Turbo Boost technology which is dynamic overclocking. This lets the Core i7 laptop to enhance performance of a specific core drastically. The 1.73 GHz version can as a result enhance one of it’s cores to 3.06 GHz. With this functionallity the Core i7 can adapt to any given situation in accordance with performance requirements. It can increase one core or turn cores of depending on the number of applications being executed at any given moment and whether the programs are single or multi threaded. This is a very good feature in the Core i7 laptops since it will help decrease power expenditure from the battery.

The Core i7 for laptops also supports Hyper Threading like the Core 2 quad CPUs but the Core i7 multitasks over 8 threads instead of 4 allowing for better spreading of tasks accross the cores.

The Core i7 has been tested by PCPro. They simply commented: "It is very, very fast". In their application benchmark the Core i7 laptop was based on the 1.73 GHz CPU and the specs of the hardware were very mediocre, but it still scored 1.59 which is very close to 1.64 scored by the extreme Dell Precision M6400 Covet in the very same test.

PCPro also tested the Turbo Boost functionallity by first loading one core to it’s limit and true enough the clock speed rised to 3.06 GHz and power expenditure to 58W. They carried on to load a second core to full resulting in clock speeds dropping to 2.8 GHz while power consumption rose to 70W. Adding loads to the remaining cores will simply result in further decrease in the overall clock speed while power consumption peaks out at 74W.

It is possible to really stretch battery lifetime in a Core i7 laptop with the combination of Turbo Boost and Windows Vista Power Saver. {PCPro managed to squeeze 3½ hour out of a typical 4,800 mAh battery by leaving the Core i7 laptop idle, but when they pushed it to it’s limits, the battery only lasted 46 minutes|A typical 4,800 mAh battery can last 3½ hours with the Core i7 laptop in idle mode according to PCPro, but the battery is completely drained after 46 minutes if they push the CPU to it's limits}.

A Core i7 laptop trashed all benchmarks and beat just about all the records at LAPTOP, when they tested a state-of-the-art rig based on a 2.0 GHz version.
