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.

    keep in mind Pajuk, the prices Anandtech quotes.. are US dollars i think.. Reply

    Really would have liked to have seen more Intel 4c/4t and 4c/8t cpu's for comparison, like 4690k, 6700k or 7700k. I'm curious how my 4790k stacks up to amds zen+ 4c/8t cpu but from the others tested its hard to say. Reply

    AMD's CPU naming scheme is a bit of a mess now. Used to be that Ryzen 7 = 8c/16t, 5 = 6c/12t, 3 = 4c/4t but now we have 4c/8t parts mucking up the 5s. IMO they should reorder their lineup by core and thread counts by moving current Ryzen 3 to 1, and 4c/8t CPUs from Ryzen 5 to 3.

    End result: Ryzen 7 = 2700/X, Ryzen 5 = 2600/X, Ryzen 3 = 2500X/2400G, Ryzen 1 = 2300X/2200G.

    Not really, given that the Ryzen 5 1400 and Ryzen 5 1500X are 4C/8T parts from just after the initial Ryzen launch, so in essence it was messed up to begin with. Also, if we're splitting hairs, Intel used to have HT in its i3 and i7 CPUs... Reply

    Yeah.

    We don't talk about Intel's lineup and naming scheme... or lack thereof. Down that path lies madness. Reply
