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.

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.

    You missed out on what Userbenchmark would add. Luckily most of us know the answer is "nothing".

    I'm now pretty convinced that you're a Deicidium sockpuppet.
  • Spunjji - Monday, May 11, 2020 - link

    Oh for crying out loud. The first two posts in the comments wasted on a feckless simpleton blubbering that this site doesn't do the exact same things every other site does.

    Guess what laddoo - that's the point.

    Bit disappointed with the CPU selection used in this article.

    Thought it might be interesting to see how it fares against the 1600AF or R5 3600. Different CPUs which people might be considering if they're worth the extra.
  • amrnuke - Thursday, May 7, 2020 - link

    Exactly. I'd have loved to see it up against the i3 9100F, 9400F. Comparison to the 3600 and 1600AF would be very welcome given the 1600AF's price range and 3300X vs 3600 would be very interesting from a gaming standpoint.
  • DanNeely - Thursday, May 7, 2020 - link

    None of those CPUs are in Bench, so Ian doesn't have any of them to test. The original 1600 is present for the older benchmarks, but not the newer ones. I wouldn't expect many CPUs to be run on the new ones until all of them are finished and ready to go in order to minimize the amount of time spent dis/reassembling test systems.
  • flyingpants265 - Thursday, May 7, 2020 - link

    Bench is terrible, it's missing way too many options. Most common problem I run into is when I'm trying to compare an older card (7870 or gtx660 or something) to a newer card, and they are just missing from the list. Just needs to be expanded and improved.
  • 0ldman79 - Thursday, May 7, 2020 - link

    That's because the data sets don't overlap.

    They were run with different CPU, OS, etc...

    I'd like for there to be a checkbox that says "these aren't scientific, you can compare incomplete, incorrect data at your own risk" etc, but there's a reason they aren't in the same listing; they're not the same.
  • Zizy - Friday, May 8, 2020 - link

    The problem is that such data is often very misleading. By far the most important issue: there are many drivers touting >10% speedup in game X. You might as well guess which GPU is faster if they end up very close over many generations. Heck, simple "the new GPU has X% more CU and Y% higher frequency vs old one" is likely to lead to a better estimate than trying to correct for all that mess.
  • regsEx - Thursday, May 7, 2020 - link

    Worst part in the test is the RAM. That set of 3200C14 memory is very expensive - $160. That making entire build pointless. For that money you can get 32 GB kit with 6-core Core i3 10400.
  • b0rnslippy - Thursday, May 7, 2020 - link

    Oh Ian doesn't have them in Bench.. How convenient for Ian. Ehem, "Dr" Ian, sorry.
