Consider a $3 \ \text{GHz}$ (gigahertz) processor with a three stage pipeline and stage latencies $\tau_1,\tau_2$ and $\tau_3$ such that $\tau_1 =\frac{3 \tau_2}{4}=2\tau_3$. If the longest pipeline stage is split into two pipeline stages of equal latency , the new frequency is __________ $GHz$, ignoring delays in the pipeline registers.
