Back in 2002 a lecturer for Computer Systems Engineering explained to me why the GHz race was ending (did end). Apparently the engineers were running into issues with clock propogation through the chip. As the leading edge of a clock propagates through a chip at say 10Ghz the wavelength is below 10mm. Thus before the falling edge the signal would have only travelled 5mm. Different travel paths and instruction times was leading the engineers to impossible asynchronous errors. It was predicted that with modern chip design would peak at 5GHz.
They never quite got that high but he was close nontheless.
