AMD Phenom II X2 N640 vs AMD Phenom II X2 X620 BE vs AMD Phenom II X2 N660

AMD Phenom II X2 N640

► remove

The 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 X620 BE

► remove

The AMD Phenom II X2 Dual-Core Mobile X620 BE (Black Edition) is a dual core processor for laptops that clocks with 3.1 GHz. Due to the missing level 3 cache, the architecture is similar to the desktop Athlon II X2 (Athlon II X2 255). The performance should be similar to a 2.8 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 X620BE is easy to overclock.

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.

The AMD Phenom II Dual-Core Mobile N660 is a dual core processor for laptops that clocks with 3 GHz. Due to the missing level 3 cache, the architecture is similar to the desktop Athlon II X2 (Athlon II X2 250 - Regor).

The performance should be similar to a 2.8 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 N660 is only as fast as an entry level Core i3-370M in synthetic benchmarks.

As a difference to the Core 2 series, the Phenom II offers an integrated DDR3 memory controller on the processor die.
