Intel Core i7-640UM vs Core M-5Y71 vs i7-5500U user experien

[kalahukassa]

You can find the CPU specification for an anylyse from Intel's ark.intel.com and this is very interesting comparison.
or compare

From the user point of view it would be interesting to know how many seconds less/more is difference in real life use.
Listing technical differencies doesnt serve the cause.

For sure M-5Y71 is 28% faster Maximum Turbo Frequency and 100% faster Maximum Memory Bandwith will cut down some seconds specially in memory and CPU intensive programs, but the question is how many seconds or minutes faster/slowlier the job will be for an user?
And how many sconds it will be cut off for non intensive programs?

Also GPU is different model; i7-640UM HD Graphics to M-5Y71 HD Graphics 5300, where base and maximum frequency has almost 100% faster.
What is the benefits for the users and how many seconds it will cut down from the previous CPU experience.

If i7-640UM is compared for i7-5500U where the base frequency is double faster and Turbo Frequency is 3 Ghz, and GPU frequencies are same as Core M, what is the benefits for the user and how she will see that benefit on i7-5500U?

Should I end up to conclusion that i7-640UM is more or less as fast as 4 years younger M-5Y71 because of the same base frequency and slighly slower Max Trubo frequency?
Can I say that it will not speedup my work allmost at all?

Can I end up to conclusion that i7-5500U is minimum 100% faster than i7-640UM because of 100% faster CPU base frequency?
Can I say that it will do processes 50% faster than older CPU?

And please keep the thread clear and do not bother to reply if you can not provide any valid information, including guessing.
