Rick Sanchez improved his portal gun program so that it only requires $90$ thousand instructions of MIPS assembly code instead. He also got tired of his super$-$computer running at a measly $7\mathrm{.}99$hz with a CPI of $1\mathrm{.}8,$ so he devised a method of improving it$.$ After stealing crystallized core processing units from the Zigerians, he found a method of giving his computer a new clock speed of $15\mathrm{.}99$hz$,$ but it dramatically reduces his throughput so that his CPI is $3\mathrm{.}7.$
