NVIDIA can save power consumption of processors Kal-El with four cores on a single value with Tegra 2, but the speed will increase by five times, although both processors generations are produced on 40 nm technology.
Kal-El processor may be the only ARM-solution on the market with four cores, produced on 40 nm technology. NVIDIA competitors prefer to release their quad-core products on 28 nm technology. In addition, the transition to the architecture Cortex A15 will raise the performance level of dual-core processors up to values comparable with the performance of quad-core solutions with Cortex A9 architecture.
Using 40 nm technology will increase the core area of Kal-El to 80 millimeters, while Tegra generation 2 processors have the core area 49 sq. mm This would make Kal-El's largest processor in the segment.
