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).
The AMD Phenom II X4 N950 Quad Core is a laptop CPU clocked at 2.1 GHz. Due to a missing Turbo and no level 3 cache, the performance of the N950 should be only on par with a Core 2 Quad Q9000. Compared to desktop CPUs, the Phenom II laptop CPUs are similar to the desktop Athlon II processors because of the missing level 3 cache. Therefore, the N950 is similar to a low clocked Athlon II X4 CPU produced in 45nm SOI.
The Phenom II includes an integrated memory controller for DDR3 (max. 1333) main memory. It supports MMX, 3DNow!, SSE, SSE2, SSE3, SSE4A.
The AMD Phenom II X4 N930 Quad Core is a laptop CPU clocked at 2 GHz. Due to a missing Turbo and no level 3 cache, the performance of the N930 should be beyond the Core 2 Quad Q9000. Compared to desktop CPUs, the Phenom II laptop CPUs are similar to the desktop Athlon II processors because of the missing level 3 cache. Therefore, the N930 is similar to a low clocked Athlon II X4 CPU produced in 45nm SOI.
The Phenom II includes an integrated memory controller for DDR3 (max. 1333) main memory. It supports MMX, 3DNow!, SSE, SSE2, SSE3, SSE4A.
