For example, we can compare the performance of a 32-bit but relatively faster CPU (higher
GHz) to a 64-bit but relatively slower speed. The 32-bit relatively faster CPU provides better
response time but with less throughput than the 64-bit relatively slower CPU. The response
time, or the user perspective performance measurement, can be more qualitative than
