Benchmarks: Our analysis explained

> 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
