pure noob question here but if HF patent is so kul, why they selling it instead of producing?? i mean, not that previous HF chips missed their spec too..
There were no "previous HF chips."
HF only made one chip, and it greatly exceeded spec (400GH spec vs 750GH given enough power).
Then they ran out of money. Their misfortune is providing AM with the opportunity to catch up and dominate the 16nm frontier.
