AMD Phenom II X2 X640 BE vs AMD Phenom II X2 N640 vs AMD Phenom II X2 P650
AMD Phenom II X2 X640 BE
► remove from comparisonThe AMD Phenom II X2 Dual-Core Mobile X640 BE (Black Edition) is a dual core processor for laptops that clocks with 3.2 GHz. Due to the missing level 3 cache, the architecture is similar to the desktop Athlon II X2 (Athlon II X2 260). The performance should be similar to a 2.9 GHz Core 2 Duo (because of the larger Cache of the Core 2 series in this clock range). Due to the missing multiplicator lock, the X640BE is easy to overclock (if the BIOS supports it).
As a difference to the Core 2 series, the Phenom II offers an integrated DDR3 memory controller on the processor die. It is manufactured in 45nm SOI and specified with 45 Watt TDP.
AMD Phenom II X2 N640
► remove from comparisonThe AMD Phenom II Dual-Core Mobile N640 is a dual core processor for laptops that clocks with 2.9 GHz. Due to the missing level 3 cache, the architecture is similar to the desktop Athlon II X2 (Athlon II X2 245 - Regor).
The performance should be similar to a 2.7 GHz Core 2 Duo (because of the larger Cache of the Core 2 series in this clock range). Compared to current Intel Core-i processors, the Phenom II N640 is only as fast as an entry level Core i3-350M in synthetic benchmarks.
As a difference to the Core 2 series, the Phenom II offers an integrated DDR3 memory controller on the processor die.
AMD Phenom II X2 P650
► remove from comparisonThe AMD Phenom II Dual-Core Mobile P650 is a dual core processor for laptops that clocks with 2.8 GHz. Due to the missing level 3 cache, the architecture is similar to the desktop Athlon II X2 (Athlon II X2 240e - Regor). Compared to the similar Phenom II N620, the P650 is specified with a lower TDP of 25 versus 35 Watt.
The performance should be similar to a 2.6 GHz Core 2 Duo (because of the larger Cache of the Core 2 series in this clock range). Compared to the current Intel Core-i processors, the Phenom II is only as fast as a Core i3-330M in synthetic benchmarks.
As a difference to the Core 2 series, the Phenom II offers an integrated DDR3 memory controller on the processor die.
