AMD Phenom II X2 X640 BE

The 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.
