Cinebench is an application which renders a photorealistic 3D scene to benchmark a computer’s rendering performance, on one CPU core, all CPU cores or using the GPU. We run the test using the all-core CPU and single-thread CPU modes.
Cinebench R15 at stock clock speeds with varying numbers of cores enabled from 1 to 18.
Cinebench R15 with the Core i9 overclocked to 4.6GHz.
Handbrake is a free and open-source video transcoding tool that can be used to convert video files between different codecs, formats and resolutions. We measured the average frame rate achieved for a task of converting a 6.27GB 4K video using the Normal Profile setting and MP4 container. The test stresses all CPU cores to 100% and shows an affinity for memory bandwidth.
7-Zip is an open source Windows utility for manipulating archives. We measure the Total Rating performance using the built-in benchmark tool. The test stresses all CPU cores to 100% and shows an affinity for memory bandwidth.

The summary here is very straightforward as Core i9-7980XE is a monster performer. Provided your software is highly threaded and can use a good part of the 18 cores the new CPU is a winner at stock clocks. If you overclock the CPU it moves the goalposts clean out of sight. 18 cores beat the 16 cores of Threadripper at stock clocks but when you crank up the speed it makes the competition simply unfair.
If you look at performance per core in Cinebench single thread we can see Kaby Lake i7-7700K continues to hold the crown with its superior clock speed however the i9-7980XE kicks Threadripper all over the park.
