The Performance Index 64 app is designed to compare your Mac with other macOS devices and evaluate performance and efficiency of different configurations.

Since we are talking about a 64-bit system, we took the very first 64-bit computer designed by Apple as a conventional unit - the legendary Power Mac G5 first introduced by Steve Jobs in June 2003.

Powered by the PowerPC processors, the Power Mac G5 was so effective and energy efficient that in autumn 2003 a group of enthusiastic students introduced the System X supercomputer, combined with 1100 of such desktops. This supercomputer became a real technological breakthrough, taking third place in the TOP-500 rating.

Nowadays, such a result would be impossible. If we would have combined a similar configuration of 1100 top 64-bit desktops, the resulting supercomputer wouldn’t even be included in the TOP-100 of the world ranking.

With the help of our application you can find out how much of the legendary Power Mac G5 your Mac contains. Then, you can compare your Mac with the powerful Mac Pro powered by Intel and Macs with the new Apple M1 chip.

Poor programming, and they hide the true cost

This program only tells you how much you are up for per month after you have run it. Then if you decide you do not want to proceed the program will not let you exit, the Mac wont restart until you close the program, the program refuses to close. I had to hard reboot my M1 to get this program to go away. Not happy at all it forced me into a hard reset and not happy they hide the true cost behind "in app purchases" DO NOT SUPPORT THIS POOR PROGRAMMING OR HIDDEN PRICING
