i have laptop lenovo ideapad 110-171KB , with internal GPU intel(R) HD Graphics 620 and external GPU AMD Radeon(TM) R5 M430 .

otherwise my processor is intel core i5-7200U 2.5GH up to 2.7GH with 2 cores .

i need to upgrade this processor with 4 cores and at least 3.6GH 

is it possible ?!

You need to ask Lenovo what processors are compatible with their BIOS.  Then, you can select from those.

BUT....  Your processor is soldered to the motherboard, so you cannot upgrade it.
