Comparing MIPS (or BIPS) for different platforms is useless where instruction sets are so diverse. While you say the E5-2600 is 10.5 times the BIPS of the z196, the reality is they are probably close to the same workload. Consider MVC versus MOV instructions. MVC can move 256 bytes versus 8 bytes for MOV. On the intel, 128 instructions are executed for a single MVC (a loop that increments a counter, if count not reached then loop (4 instructions). 256 bytes / 8 bytes * 4 instructions = 128 instructions needed for the single MVC instruction. Your 10.5 number now becomes 0.08. Neither of these numbers comes close to reflecting a true comparison.
