Sell your iPad today at tradelectronics Sydney for best offer! IPad 4 doesn’t look the same from outside, and the shell, screen and even size and weight are the same as iPad 3. The biggest change is that the external interface is changed from 30 needles Dock that has been used for many years to 9 pins Lightning, and second is its core : the processor is upgraded from A5X to A6X.

• The iPad 4 A6X (and A6) have all turned to Samsung’s new 32nm LP HKMG process, with core area reduced to 123 square millimeters, almost the same as the original A5, but still 27% larger than the A6.
• Both A6X and A6 use two Swift CPU kernels designed by Apple itself.
• The main frequency of A6X reaches 1.4 GHz, which is 40% higher than that of the first two generations, but only 7.7% higher than A6.

High-definition screens, backlights and 45nm processors all make the iPad 3 quite warm. The iPad 4 screen remains unchanged, but the processor technology is more advanced. It can also enter a low-power state faster under the same load, sometimes cooler.
But after all, CPU and GPU are more powerful, and long-term high load will still be relatively hot. Running “Infinite Sword 2” for one hour, the hottest places on the back were 39.1 and 39.9 degrees Celsius respectively, while the apple logo on the back was at 34.4 and 35.7 degrees Celsius respectively, and the hottest places on the back were at 39.1 degrees Celsius and 39.9 degrees Celsius. Although the difference is not obvious, it is clear that iPad 4 is still “hot” and it is best to avoid playing games for long periods of time, especially when placed on the legs.
