The AMD A8 4500M is a processor from the Trinity generation that was introduced in the second quarter of 2012. It’s equipped with four cores that are clocked at 1.9GHz- with the option of going up to 2.8GHz with Turbo Core- and integrated Radeon HD 7640G GPU which is capable of supporting Direct X 11 and is also faster than the Intel HD Graphics 4000 found in the Ivy Bridge processors. When compared to an Interl Core i3, the A8 4500M offers slightly less when it comes to performance, but it is also better suited for day-to-day work, like office work.
