|The CPU doesn't have any integrated graphics. The CPU is one of the aforementioned IC,s, the big one on the motherboard with a fan on it. Thats the CPU. The rest is the whole computer.|
Integrated graphics do not free up anything, in fact they take more of the main memory for its own use. The purpose if integrated graphics on the motherboard is that it is cheaper, you don't have to buy a separate video card. The chip-set is doing exactly the same thing with or without integrated graphics.
You don't get integrated memory except in some laptops and the cache memory that is incorporated into the CPU.
