AMD Phenom II X3 P840 vs AMD Phenom II X3 N830

AMD Phenom II X3 P840

► remove

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).

AMD Phenom II X3 N830

► remove

The AMD Phenom II X3 N830 is a tripple core processor for laptops that clocks with 2.1 GHz. It is based on the desktop Athlon II X3 processors (at a lower clock speed) and therefore features no level 3 cache. The performance should be on average on par with an old Core 2 Quad Q9000. The lack of a Turbo Boost / Core function and level 3 cache and the slow core clock limit the performance of the CPU. In single threaded applications, the performance is only as fast as a 1.8 GHz Core 2 Duo (CB10) or even slower (SuperPi). Compared to a modern Core i3-330M, the N830 stays nearly always clearly below (except in the CB11.5).

The Phenom II feature an integrated DDR3 memory controller on die (maximum DDR3-1333) and is manufactured in 45nm SOI (Core i3-330M 32nm).
