FUD Zilla heard AMD is planning to release the Athlon II X4 615e sometime later this quarter. This quad-core chip will be clocked at 2.5GHz and is expected to end up with a 45W TDP.
The name is Athlon II X4 615e is based on Propus without L3 cache, and its quite impressive that a 2.5GHz quad-core can run at quite low 45W TDP. The CPU has 4x512KB L2 cache and gives quite good performance.
This CPU will top and replace the current 45W low power leader, Athlon II X4 610e that works 2.4GHz. AMD also has 25W dual core Athlon II X2 2x0u CPUs but these guys have the top frequency of a rather unimpressive 1.8GHz.
