Multimedia, Compression and Semi-Synthetic Benchmarks
x264 is a free software library for encoding video streams into the H.264/MPEG-4 AVC format. x264 FHD measures how efficient a system is in encoding H.264 video and produces results in frames-per-second. H.265/HEVC video encoding is the future of video able to compress significantly larger resolution videos including 4K and make streaming a possibility. The 8700k ran the x264 FHD benchmark at an average of 47.36 frames per second.
x265 is an open-source implementation of the H.265 standard and x.265 HD benchmark tests the CPU’s ability to process an HEVC video. This benchmark is run by the processor alone. With its additional 2 cores and 4 threads, the 8700k averaged 27.67 FPS. For comparison, I’ve added results from previous generations.
The 7-zip benchmark shows a rating in MIPS (million instructions per second). The rating value is calculated from the measured speed, and it is normalized with results of Intel Core 2 CPU with multi-threading option switched off. So, if you have modern CPU from Intel or AMD, rating values in single-thread mode must be close to real CPU frequency. There are two tests, compression with LZMA method and decompression with LZMA method. Once the total passes reach 100, the score is taken. The 8700k hit 38449 MIPS (million instructions per second) after 100 passes. 100 passes took about 19 minutes.
WinRAR is a file archiver utility for Windows, developed by Eugene Roshal of win.rar GmbH. It can create and view archives in RAR or ZIP file formats and unpack numerous archive file formats. The chart shows a generational increase from the 6700k, to the 7700k and the 8700k being the fastest at 19270 KB/s.
HandBrake is a free and open-source video transcoder, originally developed in 2003 by Eric Petit to make ripping a film from a DVD to a data storage device easier. Essentially, it can convert video to almost any modern format. HandBrake is available for Linux, macOS, and Windows. The workload video file is a ~6.27 GB, 3840 x 1714, 73.4 Mbps, 24fps, H.264, .mov video file that is transcoded to a ~1480 MB, 1920×858, ~17.1 Mbps, 24fps, H.264, .mp4 video file. The 8700k encoded the file in 4 minutes and 8 seconds. This was a few seconds slower than the 7700k, but much faster than the 5820k and 6700k.
