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.

Benchmark Underestimates MacPro 12 CPU 24 Thread GFLOPS

I ran the benchmark on MacPro 2010 with 2 x 6Core x 3.33 GHz CPU.
Activity monitor refleted only 16 out of 24 CPU virtual threads.
16 GFLOPS using 100% CPU utilization (Single Core)
182.6 GFLOPS using 1000% CPU utilization (Multiple Core)
12 CPU Cores (24 CPU Virtual Threads) should be closer to 384 GFLOPS

As close to malware as I've seen yet...

Downloaded this and, like others, couldn't get past the ad demanding subscription. So I did a force-quit of the app.

To my surprise (and anger) I used an uninstaller program to delete this app and discovered ... wait for it ... the app and all the cruft they installed was a WHOPPING 925 MBs!!

No idea what kind of crap they're downloading, but this should be removed from the app store and pronto.

Program wont even load/preview without automatically pushing a subscription trial. The trial has no closing action, and will create an always running, undeleteable app in your dock. Zero stars was not an option
