AMD Phenom II X3 P840

The AMD Phenom II X3 P840 is a tripple core processor for laptops that clocks with 1.9 GHz. It is based on the desktop Athlon II X3 processors (at a lower clock speed) and therefore features no level 3 cache. The low clock speed and missing level 3 cache leads to a rather slow performance, but enables the use in smaller laptops (14", 15") due to the TDP of 25 Watt. The performance should be on average between a 1.8 GHz and 2.4 GHz Core 2 Duo depending on how many cores are used.

The Phenom II P840 features an integrated DDR3 memory controller (on die).
