Used the world over by amateur and professional videographers, Premiere Pro is an important workload for any CPU these days. Our test involves exporting real, in-house footage from one of the videos on our YouTube channel. It is roughly 1GB of 4K footage including an audio track and transition effects, and we export it using the built-in YouTube 4K preset with H.264 encoding. GPU acceleration is enabled just as it would be normally, but the test is very heavily CPU-bound.
We perform a simple transcode using the freely available HandBrake software, which converts a 150-second, 917MB, 4K, MKV video sample to a 1080p MP4 file using the HQ 1080p preset. Our results show strong scaling with increasing threads, which is indicative of high-performance video editing suites, albeit without any GPU acceleration.
This workload involves making a series of adjustments to a set of photographs using ImageMagik - an open-source image processing library - to adjust brightness, contrast, saturation, and gamma. When a favourable balance is found, the changes are then applied to the rest of the images in the set. TIFF files up to 67MB in size are used. We disable GPU/hardware acceleration for this test to place added emphasis on the CPU's capabilities.
