How do the SPEC CPU benchmarks address the deficiencies of Whetstone, Dhrystone, and Linpack?

What problems do the SPEC CPU benchmarks solve that the Whetstone, Dhrystone, and Linpack benchmarks don't?

A benchmark program to evaluate the performance of a processor spends 80% of its time on floating-point commands and 20% on non-floating point commands. A design team wants to obtain an overall speedup of 40% over the existing run time of this benchmark program by speeding up ONLY the non-floating point commands. What should be the ratio of the non-floating point commands new runtime to that of its old runtime? Select the best answer. This is a trick question! In this scenario, it is impossible to speed up only the non-floating point commands to obtain an overall 40% speedup! 2 0.5 2.5
