This combination of clock speed and core count would put it head and shoulders above any other processor on the market, so the demonstration was more than a little surprising. It now turns out that Intel forgot to mention an important detail: the 5GHz processors were overclocked, a lot, using chilled water coolers capable of handling thermal loads of up to 1.77kW.
