2.3GHz Quad Core ? Where did you get that info ?
i3 is dual core with Hyperthreading (2 cores 4 threads)
Hyperthreading is useless with gaming
Integrated Sandy Bridge GPU has poor performance (Intel HD 3000) . Your 1st laptop's integrated GPU isn't supported , that why it can't run without issue
Furthermore , your i3 is pretty old . Don't expect Dolphin to run well with a mere 2.3GHz CPU , not even close
The recommended CPUs for Dolphin :
Desktop : Intel Core i5 4670k @ 4.2GHz
Laptop : Intel Core i7 4700MQ @ 3.2GHz (maximum turbo speed with 4 cores active) which is equivalent to i3 4130 @ 3.4GHz(desktop)
