Your company is trying to choose between purchasing the Opteron or Itanium 2. The benchmark performance of two processors can be found in Figure 1.17. Suppose you have analyzed your company's applications, 15% of the applications are similar to art, and 85% similar to lucas. a) What is the weighted geometric mean of SPECratios for this mix of applications for Opeteron and Itanium 2? If you were choosing based on SPECratio, which would you choose? b) What is the weighted average of execution time for this mix of applications for Opeteron and Itanium 2? If you were choosing based on execution time, which would you choose? Your company is trying to choose between purchasing the Opteron or Itanium 2.
