> Geek­bench 3 sin­gle-core test

This tests the ca­pa­bil­ity of a sin­gle pro­ces­sor core. Many more com­mon tasks on a Mac will only use a sin­gle core at a time. In­tel’s Turbo Boost tech­nol­ogy comes into play here. In­dex score (higher is bet­ter) iMac Pro 10-core 3GHz Late 2017

> Hand­brake video en­cod­ing

We transcode a Blu-ray–qual­ity video file into H.264 for­mat us­ing Hand­brake to test the multi-core pro­ces­sor per­for­mance, which pushes all cores to max­i­mum out­put. Du­ra­tion (lower is bet­ter) iMac Pro 8-core 3GHz Late 2017

> TomB Raider at 5K (5120x2880)

For a real-world gam­ing test, we use the bench­mark­ing tool in the game Tomb Raider, with the graph­ics set­tings set to High and the dis­play res­o­lu­tion set to 5120x2880 pix­els. Frames per sec­ond (higher is bet­ter) iMac Pro 8-core 3GHz Late 2017

> BlackMagic Disk Speed test Read

Us­ing BlackMagic’s Disk Speed Test app, we get a read­ing for the fastest speed the ma­chine can read files from its built-in stor­age, mea­sured in megabytes per sec­ond. Trans­fer speed (higher is bet­ter) iMac Pro 8-core 3GHz Late 2017
