im a bit lost at cpu speed regarding laptops...

youve got the hq versions and the U versions , and without letters behind ity(eg i7 6700 hq , i5 6300U and i5 6500)

how do i compare them whats faster? any generation differences?

1) Small gains per generation. Maybe 5 to 10%.

2) CPU FREQUENCY

3) Number of cores/threads

Passmark can help: https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-6500U+%40+2.50GHz

This reads as:
a) two physical cores
b) each cores is hyperthreaded (another thread of code can add roughly 30% more processing)
c) 1651 score for single thread (higher is better)
d) 4359 total processing

*The SINGLE THREAD score is the most important score. It's better to have fewer, faster cores than to have more, slower cores because most programs can only use a few cores so the faster the better.

Only the more EXPENSIVE laptops have an Intel CPU with at least four cores.

I ignored the SUFFIX, however if you have any interest in very LIGHT GAMING then investigate what the best GPU is.

AMD APU's can be better but tend to have weaker CPU but stronger GPU, so that's ONLY recommended if you need the GPU enough to justify the slower CPU.

Intel iGPU's are the same. A newer 6th gen may have better than 5th gen.

In both cases, some laptops may be bottlenecking the GPU with slower system memory (DDR3/4) so adding another stick can help (to put in Dual Channel).

Again, this really only is worth discussing if light GAMING is a must on an inexpensive laptop.
