AMD Phenom II X4 P920
The AMD Phenom II X4 P920 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. For example in the single threaded CB10 test, the P920 only was as fast as a 1.6 GHz Core 2 Duo Dual-Core. In SuperPi even a 1.3 GHz Core 2 Duo was faster. If all four cores are used, the CPU can be as fast as a 2.3-2.4 GHz Core 2 Duo (e.g. T4500). In CB11.5 even as fast as a Core i3-330M. The Core i7-720QM Quad-Core is also rated at 1.6 GHz, but due to Turbo Boost and a large level 3 cache, the 720QM is noticeable faster (and more power hungry).
As the current Intel Core i3 CPUs, the P920 offers an integrated DDR3 memory controller (up to DDR3-1066). However it is still manufactured in 45nm (SOI process).
