Phenom II X3 N870 is a triple core mobile CPU based on the Champlain Core and therefore related to the Athlon II X3 Desktop Series.
It features 3 cores, clocked 2.3GHz and the fastest supported memory is DDR3-1333.
Its performance is average and decent enough to run most games at high settings fluently, if paired with the appropriate GPU, obviously. However, the most demanding games will require reduced settings to be played optimally.
