Fourth representative of the Athlon II four core range, the Athlon II X4 645 adds 100 MHz to the clock in comparison to the 640. This quad-core, then, is clocked at 3.1 GHz, which is enough to see its performance level increase a little more than 1% on the 640.

This keeps it just a little above the Intel Core i3 540. This also has two cores but at a clock of 3.06 GHz.

PROS

  • Low energy consumption
  • All-round processor at ease with most activities

CONS

  • Faster (but more expensive) CPUs are available for gaming
  • No Turbo mode

CONCLUSION 3/5

A quad-core CPU that offers performance levels at times lower than dual core models. It is nevertheless a good performer in applications that are adapted to the use of several cores.
