Why is it so mutch harder to make a 22nm cpu than a 28nm gpu?
CPU: Amd x3 720BE, GPU: XFX 7850 2gb, RAM: Kingston Hyper X 8gb ddr3 , MB: Gigabyte GA-990FXA-UD3,
Case: Cooler Master 690 II Advance, PSU: Chieftec CFT-650-14CS
Well, officially, it's because the equipment in small scale design is very specialized. Changing from 28nm to 22nm, or even 27mm, requires complete changeover in the die setting equipment. Which is expensive.
