This chipset is designed in such a way that some computing task can be handled by GPU instead of CPU as it happens in traditional chip-sets. Transferring the tasks to GPU will improve the overall efficiency of the chipset.
The AMD Kaveri has 12 cores - 4 cores for CPU and 8 cores for GPU. It is designed to support 4K resolution video output. Since the number of cores is more it is expected to give good batter backup for 9.3 hours.
The company planned to launch nine version of Kaveri chips. Three versions from A-Series, three from ULP and three from Pro SKU. The Prox SKU versions will target commercial applications. As usual AMD compared their chipset with Intel Core i7 and proved theirs is 50% faster in graphics processing. However it seems to be less energy efficient than Intel Core i7. AMD has already tied up with popular OEMs like Acer, Asus, Dell, HP, Lenovo, Samsung and Toshiba.
