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.

    No. Official AMD support and motherboard manufacturer support are two different things. As stated in the article.

    I misread the paragraph below it, but in general it's weird for AMD to put out a diagram quite that misleading. The ASRock AB350 was ~$120 when I bought it and is ASRock supported for the 3900X -- surely a decent percentage of boards can support most Zen 2 processors barring power constraints for the 16 core if a cheap budget build can?

    Not true the AM$ socket will support all Ryzen chips however not all features are available on all boards such as gen 4 as this is a specific development that was not available when the 1 series launched, also the limitation is on the power system of the board not in AMDs specs

    "CHIPSET FEATURES: Note that not all processors are supported on every chipset, and support may require a BIOS upgrade. See your motherboard manufacturer’s website for compatibility"

    I have a 3 series running in my A320 media pc in my lounge updated the bios and it works fine however i suspect if i tried a 3900 it would not have the power circuit to support it, the other issue is the bios chips in some of the older boards cannot store enough information to allow all the chips to be used, so strictly speaking the issue is with the board supplier.

    I'm still stuck on the i5-6600K which I built back in 2016. Thought it would serve me well for many years to come given the state of Intel and AMD at that point in time, and that my previous i5-2400 lasted me a good number of years while still being competitive. Now barely four years later it's obsoleted by a 100 dollar CPU lol.

    It's far from obsolete, even if it's regularly beaten. I'm still using my Sandy-E processor when I'm unopposed to simultaneously running a space heater -- it's just a question of whether you need the latest and greatest.

    Actually looking that the performance of these 4 cores chip, I can't wait to see an APU with it. Even the 4 core APU will be great for every day usage, without a graphic card. I just hope they give the 4 core version a decent graphic option, rather than a Vega 6.

    A very good review, quite in line with the others. Ryzen 3 3300X is a nasty game-changer.

    Please stop running tests that appeal to less than 5% of your audience (and I think I'm being generous here). Crysis on cpu? Who cares? What does it prove I can do today? Dwarf fortress?? WTF? Quit wasting your time and ours. AI ETH tests? What for (farms do this now)? How many tests do you need that show NOTHING to any of us?

    People should get the point. You are irrelevant at some point if you keep posting crap nobody cares to read. Ask toms hardware :) Oh, wait, you guys are toms. ;)

    How about testing 20 games at 1080p where everyone plays. :) Is it too difficult to ask a few pros to make a script for photoshop/premier/AE to test under AMD/NV (cuda vs. OpenCL or whatever is faster on AMD)? It is almost like you guys seek benchmarks that nobody could possibly find useful IRL.

    "provide a good idea on how instruction streams are interpreted by different microarchitectures."
    Your PHD project tells me how these cpus will run in WHICH PRO APP? Why not just test a PRO APP IRL? Bah...fake news. Not sure why, AMD wins everything right now. Why hunt for fake tests that mean nothing? How many people use Agisoft instead of PhotoshopCC for $10 a month?

    Still ripping at crap modes nobody would actually use. Again tells us nothing about what we REALLY do usually. Only a retard uses FAST settings in handbrake for anything but a 15fps training vid.

    "We are currently in the middle of revisiting our CPU gaming benchmarks" and upgrading to 2080ti. Can't happen soon enough, please make sure you test games that sell over 1mil ON PC or don't bother. If the sell poorly or are poorly rated, there is no point in testing them. Test what people PLAY, at settings people really use. 720p low shows what to a person who will NEVER play below 1080p? Oh wait, I just described 99% of your audience, as I'm quite sure they haven't played 720p in ages. So much wasted testing. Stop testing 4k and test more 1080p/1440p (1440p still almost useless, wake me at 10%).

    "Some of these new benchmarks provide obvious talking points, others are just a bit of fun. Most of them are so new we’ve only run them on a few processors so far. It will be interesting to hear your feedback!"

    Please quit wasting your time. It feels like all your benchmarks are "for fun" as I'm not much smarter after coming here. Off to a site that tests a dozen games and some real world stuff some of us actually use (techpowerup for example...games galore, 10 REAL games tested). THIS is how you give a well rounded idea of a cpu/gpu perf. YOU TEST REAL STUFF, instead of your PHD crap or agisoft junk. People use adobe, and play games that SELL. This isn't complicated people.

    Might as well jump off the roof with your cpu and tell us how fast you hit the ground. Just a useless as your benchmarks. Are they benchmarks if nobody uses them? Or is it just more "fun" crap tests that tell us nothing useful? If you are NOT helping me make a more informed decision (useful info) about buying the reviewed product, you have failed. A good review is chock full of useful info related to how we actually use the product, not a bunch of crap nobody cares about or use IRL.

    The devs make 3K a month from it. This is not exactly played by the world if it pulls down $35K a year. Why even bother testing this crap? Are we all going to go back to pixel crap graphics tomorrow? Heck now. Wake up. Those games (and the shite monitors we had then) are why I needed lasik...ROFL.

    "Only a retard uses"
    And that's about where I realised you weren't really making a comment so much as farting into a piece of voice recognition software.
  • Meteor2 - Tuesday, August 4, 2020 - link

    I wonder if even one single person ever read that comment
