What is the difference between a graphics subsystem and an integrated graphics card?

Question

Iron

There are 2 processors
ark.intel.com/ru/products/52209/Intel-Core-i5-2500...
ark.intel.com/ru/products/82932/Intel-Core-i7-5820...
One has graphics subsystem and the other does not.
If there is no built-in video card, then we can connect a monitor to a discrete video card.
Then what role does the graphics subsystem play in the processor if the built-in one has its own resources?
And, if the processor does not have a graphics subsystem, how much am I losing? for games.
ps correct me if something is not correctly described.

Answer 1

You have confused some terms. Discrete is the external one. the graphics core in generations (intel) is also different. Get to grips with the terms.
