Alice designs a 2 GHz processor where two important programs, A and B, take one second each to execute. Each program has a CPI of (1.5). Elena is tasked with designing the company's next-generation processor. She comes up with an idea that improves the CPI of A to 1.1 and the CPI of B to 1.4. But the idea is so complex that the processor can only be implemented with a cycle time of 0.6 ns. Does Elena's new processor out-perform Alice's processor on program A? How about on program B?
