The chips are capable of exchanging data at a terabyte a second, Otellini said during a keynote speech. The company hopes to have these chips ready for commercial production within a five-year window. Intel uses its twice-yearly conference to educate developers on its long- and short-term plans. Over three days, hardware developers and partners get a chance to interact with Intel employees and take classes on new technologies.
