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.

    Tell that to AutomaticTaco, his posts read like a shill mission atm.

    How is the 2600X beating the 2700X in Ashes ?
    How is the 1800X beating the 2700X in AES?
    2700x results are too low in some areas.

    Did I just fu*king downgrade by purchasing the i9 9900K when I have the i7 8700K? Like WTF? Some gaming results show the i7 is beating the i9. Like what is going on here? The i9 should be ahead of both the i7 8700K, and 8086K in all gaming tests considering it has 2 extra cores. Once again WTF is going on here with these results? They are inconsistent and make no sense!

    @Ian / Anandtech: With the high premium over the MSRP for a 9900K, the difference vs. an 8700K is easily $ 200 as of now. So, here a suggested comparison that even stays in the Intel family: A comparison of a system with the 9900K with the (obligatory) high-end air cooler (so, another $ 100) vs. an 8700K based system at the same price point. Both with the identical graphics card (1080 GTX or 2070), but with the money saved with the 8700K then spent on delidding, a nice liquid cooler AND really fast DDR4? I believe that latter could really make a difference: While Intel's memory controller specifies rather slow DDR4 RAM, it's well known that one can effectively make use of much faster DDR4 RAM, and that has been shown repeatedly at least for the 8700/8700K. So, in a dollar-for-dollar matched comparison, would the 9900K then still be the king of the hill? I, for one, doubt it.

    I have to recall my own comment, after checking prices at Newegg and Amazon. The current Intel 14 nm shortage has now also driven 8700/8700K prices far above their MSRP. This invalidates the performance/price = value equation my comment was based on, although the 8700K is still notably less than the even more overpriced (and out of stock) 9900K. Right now, building an Intel i7 rig is really questionable, unless one really, really wants (thinks one needs) those last few fps in some games and has plenty of money to burn. Assuming one uses the same video card, a Ryzen 2700 (or 2700x) setup with 16 GB of fast DDR4 RAM is cheaper, and if overclocking is on your mind, spend the difference to an 8700 (K or not) on a good liquid cooling setup.

    For gaming, what it effectively does is push the "on the same budget" equation firmly into the camp of buying a 2700X and using the saving to get a better GPU. Only time this wouldn't apply is if someone does not have any kind of budget limit, but that has to be a tiny and largely irrelevant minority.
  • SaturnusDK - Tuesday, October 23, 2018 - link

    If you're planning to have a decent GPU and game at 1440p or higher then absolutely no Intel CPUs, at any price point, at the moment makes sense to buy. The 2700X is less than $300 at the moment, about half the price of a 9900K, and the 2600 is $160 at the moment, about half the price of a 8700K. Both AMD CPUs match or is only marginally behind the respective core/thread Intel equivalent at double the price.

    Under the Mozilla Kraken label you have a power consumption graph.

    "Intel Core i9 9900K: The fastest gaming CPU"

    Uh, really Intel? Looks like that's the 9700K.
  • The Original Ralph - Saturday, October 20, 2018 - link

    Looks like all this might be a moot point for awhile: Amazon hasn't started shipping, Newegg is not only stating "out of stock" but "NOT AVAILABLE" and B&H photo is showing availability date as "JAN 1, 2010" - i kid not. Suspect there's an issue with intel deliveries
