In the fall, I plan to use my desktop mainly for internet, movie and school works. In general, I see that the mobile process ha bigger L2 cache and was wondering if that will greatly affect my usage performances? Will I notice the differences? Thanks for all your help!
You won't see any difference with Internet, movies, or basic programs like microsoft office(I'm not sure what you use for school) The performance difference between those processors are very minimal, and those types of programs aren't processor bound, most any processor will run them at the same speed.
The desktop will be faster simply because it is a desktop.
There are many factors that will cause the laptop to be considerably slower. And it will get slower as you load more apps onto it.
This is a false statement. A desktop will not be faster simply because it is a desktop. It comes down to the parts. Most desktops will have a faster hdd. In this case it has more ram as well. But toss a SSD drive into a laptop and you shall see.
Also a laptop or any system for that matter does not get slower as install more apps. I'm assuming you ment install apps and not loading up mulitple apps. Either way it is simply not true.
