well, if it is cheap, laptop or desktop, you really should not expect much from it.
while it is true that in 3 years time you will probably replace even your monitor, the thing is, you can get better performance by buying selected parts without replacing your case, monitor, etc. unlike a laptop that you basically replace everything.
and yes, mobile gpu/cpu's are slower due to thermal issues. imagine that heat source (gpu) with a gigantic cooler, try cramping that same heat source and cramp it into a laptop body. so they have to tone things down to compensate, otherwise it might melt
