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.

    I love the price of $488 stamped all over each of the test results, while over here in UK I see price of £599 and newegg quotes $580. Even your linked amazon has it at $580. And conclusion is awesome with: "At $488 SEP, plus a bit more for 'on-shelf price'..." Since when is extra 100 bucks a bit more? :D

    What was the actual vcore for your overclocks?

    I7-9700k.... an I7 that isn't hyperthreaded.... let's totally muddy the waters now Intel.... Guess they had to save some feature for the I9's $100+ surcharge...… Good grief.

    How pointless is reviewers comment: "... World of Tanks gives the 9900K some room to stretch its legs..."?
    Difference between two chips in discussion is between 712fps and 681fps! Not even Neo from Matrix could note the difference.

    How pointless is discussing top of the line CPU gaming performance in 720p in any game??

    How pointless is marketing 8C/16T CPU for gamers???

    Not sure whether this has been pointed out yet, but the Threadripper prices need to be updated. For example, the 1920X is now well under $500 as advertised even on AMD's website and the 1900X goes for $350 on Newegg.
  • dlum - Tuesday, October 23, 2018 - link

    For me, listing the long-obsolete prices for AMD processors (still initial, long-outdated MSRP for 1920x $799 - whereas a simple amazon search confirms it's now for just over half of that ($431)) is clearly disrespectful and shamefull practice for a reviewer.

    It's very sad such dishonest practices found their way to Anandtech and they are so prominent here.

    Probably that's also why no one answers nor fixes those clearly misleading figures.

    (Maybe that's the cost of being able to read such anyway valuable reviews for free :)

    Well, to be fair, I'm sure the editors didn't dig this deeply through the comments. They're busy people.

    Also, I think I heard something mentioned before about their graphs having some semi-automatic mechanism for listing prices and the like. I don't remember exactly, but it probably has something to do with pulling MSRP data and it's difficult to change given the way the templated graphs are generated from the benchmarks.

    I imagine it was done something like this for consistency across the site as well as not biasing prices according to specific vendors. Given the first reason, I don't know why it'd be difficult for individual editors to customize/tweak certain aspects, but maybe that needs to be revised to be more flexible. As for the second reason, there are clearly reasonable solutions, like finding the *current* MSRP (rather than the release MSRP), or selecting the lowest/median/average price among a pool of selected retailers.

    Anyway, it doesn't make much sense to me to characterize this as an instance of dishonesty, but rather a technical detail that's important enough to invest the time in it's improvement.

    Meh. Intel owner could simply delidd and approach these kinds of performance.
    Resolution above 1080p, AMDs parts have better value.
  • zodiacfml - Wednesday, October 24, 2018 - link

    Made the comment without reading the review. The difference is a lot smaller than I expected where the only useful difference is in Ashes where AMD usually dominates due to sheer core count.
    I'd be fine with that 6 core CPU from AMD.
