The new AMD Athlon X4 840 is all about value and should make the transition to FM2+ cheaper, provided you don't need integrated graphics. The chip is a Kaveri-based quad-core clocked at 3.1GHz. It has a max Turbo clock of 3.8GHz and a TDP of 65W. This is only the second Kaveri Athlon to launch ? and unlike the Athlon X4 860K, it's not an unlocked part. It is also somewhat slower than the 860K, which clocks in at 3.7GHz (4.0GHz Turbo), but the 860K is a 95W chip.
