CPU Information
Model 240e, with OEM part number AD240EHDK23GQ and box part number AD240EHDGQBOX, is a low power version of Athlon II X4 240 CPU. This processor was released in October 2009 together with a group of other energy-efficient Athlon II microprocessors. Built on the same Rana core as other members of Athlon II X2 family, the 240e runs at 2.8 GHz and features 1 MB level 2 cache per core. With Thermal Design Power (TDP) just 45 Watt, this processor is a perfect fit for low-power systems, like HTPC or always-on office computers. As a comparison, the best dual-core AMD desktop CPU with 45 Watt TDP, based on older K8 microarchitecture, was
Athlon 64 X2 5050e. The 5050e runs at 2.6 GHz and has twice smaller L2 cache. As a consequence, model 240e has 15% - 50% better performance than the 5050e.
