Before we compare online gaming between tablets and mobile phones, it is instructive to look at how these two technologies are developing.
First, in terms of computing power, they are both getting very much more powerful. The latest generation of smartphones have 1.6 GHz eight core processors, which by any standard is very impressive. At the time of writing, there were no tablets with eight core processors, though we do know that they are in development.
Second, in terms of display technology tablets and smartphones are converging. The trend is for tablets to get smaller whilst the latest smartphones tend to have larger displays. The largest smartphone display is 6.1 inches, the Ascend Mate from Huawei, the Samsung galaxy Note II has a 5.5 inch display, and there are several smartphones with 5 inch displays. On the other hand the sizes of tablets are getting smaller; tablets with 7 inch displays are particularly popular.
With less than one inch separating the two technologies, it is becoming increasingly difficult to say in general terms which is the best for online gaming. Ultimately it comes down to user preferences. There is a huge difference between playing online games on a 10 inch iPad and on an iPhone with a 3.5 inch display, but the difference in the online gaming experience between a 6 inch phone and a 7 inch tablet is not very much.
It also depends on the types of games you play. If you play big immersive multiplayer games then you are likely to favour a tablet, and probably a large one, but if you play online casino games at www.iphonecasino.com.au such as roulette, blackjack and slots, then there is little to gain from having a large display but a great deal to gain from the added convenience of a mobile phone.
