MagyarAMD Phenom II X3 P840 vs AMD Phenom II X3 P820 vs AMD Phenom II X3 N870
AMD Phenom II X3 P840
► remove from comparisonThe 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 P820
► remove from comparisonThe AMD Phenom II X3 P820 is a tripple core processor for laptops that clocks with 1.8 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 1.7 to 2.3 GHz Core 2 Duo depending on how many cores are used by the application. Therefore, the CPU is located in the entry level in 2010.
The Phenom II P820 features an integrated DDR3 memory controller (on die).
AMD Phenom II X3 N870
► remove from comparisonThe AMD Phenom II X3 N870 is a tripple core processor for laptops that clocks with 2.3 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 2.1 GHz Core 2 Duo (CB10) or even slower (SuperPi). Compared to a modern Core i3-330M, the N870 stays nearly always 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).
