Can Gaming Laptops compete with Gaming Desk Top Computers?

How can Gaming Laptops compete with the much larger Gaming desk top computers? I have heard that Gaming Laptops use the APU to provide graphics where Desk Top types usually have a separate dedicated Graphics card(s). I couldn't find a good Youtube video about it. Can anybody give me a link?

  • The big difference between gaming laptop and desktop is power and cooling.  If you have the same gpu in both the desktop and laptop, the desktop model will be stronger able to pull more power and run hotter.

  • So do you believe the much larger size is of a desktop computer is for driving things like bigger fans, bigger electronic components, bigger monitors, big screen TVs, fancy lights, larger power supplies, multiple monitors, and there is no real performance difference to justify the size other than bigger is more impressive and therefore better?
