what does mean that 2557M in for example Intel® Core™ i5-2557M Processor
(3M Cache, up to 2.70 GHz) Please...

Just intel constantly pumping out more mobile processors. They just lower the voltages or clock it 100mhz or so higher in order to justify selling them.

That should tell you everything you need to know about the processor, Its an ultra low voltage model, designed for ultrabooks or very thin notebooks.

When it says 3mb cache its referring to the level 3 cache, which is a small very fast form of memory found in the processor of the computer. Instead of having to be constantly fetching the data from the primary memory unit (hard drive), it copies it into the cache, in which it can retrieve at a much faster rate than from the HDD. The larger the cache, the more information can be copied to it, resulting in faster processing speeds.

When it says up to 2.7ghz, it is referring to the front side bus X the CPU multiplier. Normally the higher the better, but their is many factors that have to be taken into account in order to determine the actual performance of the processor (such as hyperthreading, or the architecture it is based upon)
