Integrated graphic

This is some story about integrated graphic processor in north bridge or center processor. Not every day people will think integrated graphic is good and important. Most people will use another PCI-E graphic card to boost 3D graphic performance or video processing, why do we still need to have an integrated graphic?

I once thought that it was a wasteful use of resource to assign more silicon die area for this dumb device, especially when I saw intel integrate those graphic processing unit into their center processor. But I do realize that there is a fact nowadays, graphic card getting more easy to malfunction as the power consumption of it increase over time but their heat sink remain the size of about 2 PCI slot.

I have never seen a CPU malfunction so far, but I do getting few chances to know or witness the malfunctioning of modern graphic card. Therefore I guess modern 3D graphic card required better heat dissipation, such as proper air circulation and more clear space for air, this is what unlikely to occur on most desktop or laptop design.

I experienced a malfunction of a graphic card before, at the moment I really needed the computer to do some important task for me. Thank to the integrated graphic, and fortunately thing was done in time. And I realize, having integrated graphic isn't a bad idea because modern 3D graphic chip just isn't very reliable.
