The Apple tablets use the A8X chip and 64-bit A7 chip. The Qualcomm’s Snapdragon 805 is superfast on Android Tablets.
The more RAM size in a tablet, the faster and interactive it will be. The best RAM size is 2GB but at least 1 GB of RAM is adequate for an Android tablet. 2 GB RAM size is the minimum for windows 8.1 tablets.
For an educational tablet it should have at least 8gb internal/phone storage.
This is a useful place to store downloads, videos, photos, assignments. etc. Therefore the minimum size should be 16GB and we suggest 32GB to be ideal.
