With all the hype of quad core processor going on and with numerous devices have been displayed at MWC running the latest Tegra3 quad core processor from NVidia it’s about time we take a look at the chipset and find out what makes it so powerful and battery efficient.
NVidia first introduced the new processor last year under the code name project Kal-El that will be featuring four cores along with 42 GPU units that will boat impressive 3D performance.
Then Last September NVidia made an announcement regarding the Kal-El processor that it will be featuring a new 5th core called the companion core that will be handling all the day to day task of the phone.
The 5th core will be a low power core running at 500 MHz and will handle all the less processor intensive tasks such as keeping your twitter feed updated, keeping your email updated and handling all the misc. tasks.
The remaining four cores will be powered down to conserve the battery. As a result the battery life of the devices running the Tegra3 will be tremendous because according to the NVidia the 500 MHz companion core hardly takes any power and the battery life will be better than what you would have expected from the dual core devices.
5th Core Is Now Known As VSMP core
Now NVidia has trademark the fifth core as the VSMP core and names their entire architecture as the 4-PLUS-1 architecture and in the future when you will be reading about the tegra3 processor, you will be coming across the 4-PLUS-1 architecture a lot.
Now most of the user might ask that, what is the point of having a quad core device if the fifth low power core is handling all your tasks and most of the time the major players are sleeping.
Well the four major cores will only be used when you are about to run any graphic intensive task which requires lot of processing power such as games or watching any kind of HD videos on your device.
The devices will need that kind of horsepower because the quad core devices are coming with HD display and high resolution. To compute such high resolution and to run full HD videos without any hiccups you need those four cores to work together.
Even during web browsing the page load times are decreased letting you surf the web very efficiently and smoothly.
To this high performing efficient processor add the latest version of android, Ice cream sandwich and you get an amazing package because Android 4.0 is highly energy efficient and also manages the background task very efficiently thus making sure that the Fifth core or the ninja core even works much more less.
So all in all NVidia have produced a very efficient chipset that is able to provide the computing powers that can rival the processor that is found in budget notebooks and netbooks.
To compete with NVidia’s energy saving 4-PLUS-1 architecture Samsung have tried designing their own energy efficient Exynos chipset from ground up. Samsung are thinking of employing a quad core design that employs two high performance cores that runs at 1.5 GHz and the remaining two cores will be running at 800 MHz
The quad core Exynos chipset will be featured in Galaxy S3 and only after its release can we tell which is better whether NVidia’s Tegra3 or Samsung’s Exynos
