What does X2 RM-72 Dual-Core mobile processor mean?

X2 dual core is from AMD and competes against Dual core duo from Intel.

they are next generation of processors from respective comapnies and

their core microarchitecture provides more efficient decoding stages, execution units, caches, and buses, reducing the power consumption of Core 2-branded CPUs, while increasing their processing capacity.

I think they all are 64 bit therefore they support more memory natively hence better for memory hungry applications, they certainly help high def gaames, movies, music etc. Even though high def depends more on how powerful is your graphics card, it helps to hold entire movie or game in the main memory for faster access.

here are couple links for more information:

The Turion X2 is AMD's most current dual core processor, intended to compete with Intel's Core 2 Duo.

The name RM-72 refers to a specific 2.1GHZ model in the Turion X2 family.

Generally speaking, AMD processors are run slower and is less efficient than Intel Core 2 Duo's, as most review sites point out:

So if you have a choice, opt for a Intel Core 2 Duo laptop instead.

Most mainstream laptops have at least 2.2 Ghz which is all you require for general multitasking.

If you are into heavy apps like Photoshop or video encoding, a 2.6 Ghz Core 2 Duo may be a better solution.
