Before running our tests, we were believing the Athlon X4 845 should present lower performance than the FX-4300 and the A10-7870K, because of its lower clock and cache memory.

However, it seems like the new Excavator architecture, with the Carrizo cores, reached a good balance of performance and power, being actually faster than the FX-4300 and the A10-7870K in some tests, including games. Besides that, it uses less power, which is always welcome.

So, we concluded that the Athlon X4 845 is a CPU with excellent cost/benefit ratio, and even if it is not the right choice for a high performance computer, it is an excellent option for a budget PC for work and gaming.
