Most of the new tablet PCs uses Mali 400 or Tegra 3 GPU for 3D acceleration of games and videos. Mali 400 is from ARM, this is older GPU when compared to tegra 3, there is newer version of Mali GPU available but still most of the tablet makers prefer Mali 400 hardware. Tegra 3 is from NVidia which is known for graphic cards. Tegra 3 is quad core CPU; here we are comparing only GPU capabilities of both the hardware’s.
Here are comparisons of Mali 400 and Tegra 3:
