George designs a processor with a clock cycle time of $3331/3$ Pico seconds. Program A executes $7\mathrm{.}5$ billion instruction and program B executes $7$ billion instruction on George$$s system. Program A has a CPI of $(2)$ and program B has a CPI of $(3)$ on George$$s system. Scott is tasked with designing the company$$s next$-$generation processor. He comes up with an idea that improves the CPI of program A & B to $(1\mathrm{.}6).$ The new idea is so complex that the new processor clock speed can only run at $2$ GHz$.$
