Can this difference affect power management & performance?

MacBookPro8,2 probably has dual-GPU, which is why you see GPU PM profile for Vendor 1002 (ATI).
The extra profile data probably has no effect when you don't have an AMD/ATI GPU, but probably best to avoid MacBookPro8,2 unless you have matching hardware.

You can check hardware specifications for Apple hardware at everymac.com.

I have the same CPU of 8.2 but HD 3000 only. Can this affect anything?

Since MacBookPro8,2 is dual GPU (Apple proprietary GMUX) and your laptop is Intel only, you should probably not be using MacBookPro8,2.

MacBookPro8,1 is a better choice.

Even if my laptop has the same identical CPU model -i7 quad core QM- as 8.2 ?

CPU is not the most important criteria.
Often times, the dual GPU SMBIOS causes problems for single GPU hacks.

So, choosing smbios based on GPU is more important than the CPU similarities or generation or number of cores?
i mean, isn't choosing smbios like Macbook Pro 8.2 -which has identical CPU- for my hack is like a real macbook pro 8.2 with a failed/disabled AMD gpu?

No idea what you mean by "is masking a real macbook pro 8.2 with a failed/disabled AMD gpu?".
