AMD Phenom II X4 P940

The AMD Phenom II X4 P940 is a slow clocked quad-core CPU for laptops. Compared to the desktop Phenom II, the mobile Phenom II X4 offer no level 3 cache and are therefore compareable to the desktop Athlon X4 line. The slow clock speed allows the low powerconsumption (25 W TDP) but may lead to a bad performance in single threaded applications and games. The single thread performance should be between a 1.4 GHz and 1.7 GHz Core 2 Duo processor. If all four cores are used in benchmarks, the performance may reach the level of a Core i3 processor.

As the current Intel Core i3 CPUs, the P940 offers an integrated DDR3 memory controller (up to DDR3-1066). However it is still manufactured in 45nm (SOI process).
