exynos Samsung launches low power quad core CPU for smartphones and tablets

Samsung has launched the Exynos 4 Quad application processor for smartphones and tablets, which is the first in the industry to use the High-k Metal Gate (HKMG) low-power process technology.

Samsung has launched the Exynos 4 Quad application processor for smartphones and tablets, which is the first in the industry to use the High-k Metal Gate (HKMG) low-power process technology.

 
The 1.4GHz quad-core processor is based on the ARM CORTEX A9 architecture, offering higher performance, such as full high-definition 30fps video, but at 20 percent less power cost than previous models, such as the Exynos 4 Dual. This is due to the use of 32nm HKMG technology, dynamic voltage and frequency scaling, and hot-plug functionality for switching on and off individual cores.
 
The Exynos 4 Quad has the exact same form factor of the Exynos 4 Dual, making it pin-to-pin compatible, which means mobile device designers can incorporate it into existing designs.

“The quad-core processor offers phenomenal multitasking abilities surpassing any single or dual application processor. Since all the cores must share a single battery, the power management and efficiency in the limited battery capacity are indispensable for mobile computing devices,” said Taehoon Kim, VP of System LSI marketing at the Device Solutions division of Samsung. “Given the diverse functionalities consumers are demanding from their mobile devices today, the Exynos 4 Quad meets those high-performance needs while keeping power consumption very low.”
 
The chip is already in production and will see its debut in the next Galaxy smartphone, which will be announced in May. Samples have also been sent to other handset manufacturers.
