Tegra 4 GPU vs others
Tegra 4 sports same fabrication technology like its competitors, taking the size of transistor down to 28nm, making them power-efficient even at higher clocks by large margin from Tegra 3’s 40nm fabrication. Tegra 4 GPU is a powerhouse, it packs 72-core graphics on chip, and is six times as many GPU cores as Tegra 3, 20x boost from the Tegra 2. Tegra 4 Graphics performance can beat Apple A6 GPU but not A6X.
