CPU Performance: Encoding Tests

With the rise of streaming, vlogs, and video content as a whole, encoding and transcoding tests are becoming ever more important. Not only are more home users and gamers needing to convert video files into something more manageable, for streaming or archival purposes, but the servers that manage the output also manage around data and log files with compression and decompression. Our encoding tasks are focused around these important scenarios, with input from the community for the best implementation of real-world testing.

All of our benchmark results can also be found in our benchmark engine, Bench.

Handbrake 1.1.0: Streaming and Archival Video Transcoding

A popular open source tool, Handbrake is the anything-to-anything video conversion software that a number of people use as a reference point. The danger is always on version numbers and optimization, for example the latest versions of the software can take advantage of AVX-512 and OpenCL to accelerate certain types of transcoding and algorithms. The version we use here is a pure CPU play, with common transcoding variations.

We have split Handbrake up into several tests, using a Logitech C920 1080p60 native webcam recording (essentially a streamer recording), and convert them into two types of streaming formats and one for archival. The output settings used are:

  • 720p60 at 6000 kbps constant bit rate, fast setting, high profile
  • 1080p60 at 3500 kbps constant bit rate, faster setting, main profile
  • 1080p60 HEVC at 3500 kbps variable bit rate, fast setting, main profile

7-zip v1805: Popular Open-Source Encoding Engine

Out of our compression/decompression tool tests, 7-zip is the most requested and comes with a built-in benchmark. For our test suite, we’ve pulled the latest version of the software and we run the benchmark from the command line, reporting the compression, decompression, and a combined score.

It is noted in this benchmark that the latest multi-die processors have very bi-modal performance between compression and decompression, performing well in one and badly in the other. There are also discussions around how the Windows Scheduler is implementing every thread. As we get more results, it will be interesting to see how this plays out.

Please note, if you plan to share out the Compression graph, please include the Decompression one. Otherwise you’re only presenting half a picture.

WinRAR 5.60b3: Archiving Tool

My compression tool of choice is often WinRAR, having been one of the first tools a number of my generation used over two decades ago. The interface has not changed much, although the integration with Windows right click commands is always a plus. It has no in-built test, so we run a compression over a set directory containing over thirty 60-second video files and 2000 small web-based files at a normal compression rate.

WinRAR is variable threaded but also susceptible to caching, so in our test we run it 10 times and take the average of the last five, leaving the test purely for raw CPU compute performance.

AES Encryption: File Security

A number of platforms, particularly mobile devices, are now offering encryption by default with file systems in order to protect the contents. Windows based devices have these options as well, often applied by BitLocker or third-party software. In our AES encryption test, we used the discontinued TrueCrypt for its built-in benchmark, which tests several encryption algorithms directly in memory.

The data we take for this test is the combined AES encrypt/decrypt performance, measured in gigabytes per second. The software does use AES commands for processors that offer hardware selection, however not AVX-512.

    better then the typical Intel.. overpriced, and not much gained

    How many folks with GTX1080s would be using either of these CPUs tested (even if they were for sale)? :) Reply

    Someone that decided to start gaming, or changed to a game that required more graphics power so bought a graphics card. Maybe a kid whose parents bought a computer, or a hand-me-down computer. Even I have been gaming and building computers a long time and I have upgraded the graphics card on my computers several times around the middle of that system's lifetime (I keep them pretty long). I have friends that play WoW and needed to upgrade.There are plenty of situations.

    Have you seen gaming benchmarks with low end CPUs vs high end CPUs when both have the same high end graphics card?

    wrong power consumption test ...

    Ryzen 5 2500X get DDR4 2933 (1.3 V) vs coffe lake DDR4 2667 (1.2 V).

    (for Ryzen 5 2500X clock up ram freq to 3200, or downclock to 2667)

    ty and sorry for my eng.

    another intel biased review . Why didint youput the price of the i5-8600k like in other reviews??
    maybe because you know that it costs the same as amd 2700 ??? tired of LIARS.

    The statement by Pajuk is actually not correct - the i5-8600k costs $288.96 boxed, the Ryzen 7 2700 229.99 - both at Newegg - so it's not the same price but $60 more. Reply

    you help me even more, this LIARS in anadtech are as bad as tomshardware. Reply
