A computer system is using pentium-5 processor with 5 stages in pipeline processing with cycle time of 5ns, whereas another computer system is using pentium-7 processor with 7 stages in pipeline processing with cycle time of 3.75 ns. A program is executing which is containing a loop of 5 instructions in that four arithmetic instructions and a branch instruction which is at the beginning of the loop). There are dependencies in arithmetic instruction but are consecutive. Due to this dependency there are stalls in pipeline. Pentium-5 processor gives 1 stall, whereas Pentium 7 processor gives 2 stalls. Due to branch instruction Pentium-5 processor induces 3 stalls and Pentium- 7 processor induces 5 stalls. According to these statements, which one of the following is TRUE?

(a) Pentium 5 processor will execute the program much faster in steady state.
(b) Pentium 7 processor will execute the program much faster in steady state.
(c) Both will execute with the same speed
(d) None of these
