well life is full of technicalities;
comparing the G4400 and the I5-5200u reveals they are both close in power as per passmark.com ratings
comparing the GT 820m and the Gt1030 OC is a simpler process. the 1030 is much more powerful and capable video card
technical between the difference of the card can be found at gpuboss.com
so yes the g4400/1030 is a clear winner here even though the 5200u is a perfectly capable processor, comparing a desktop and a laptop at this point and in a lot of cases is pointless a desktop is general even with similar processor and video chipset less power than a desktop because of power consumption requirements a laptop has compared to what a pc can output.
