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.

    The issue is that it's not informed. It's codswallop.

    You're talking about the article.

    Considering it shows the $120 AMD offering comprehensively beating the old i7-7700K, and says the current Intel budget offerings will be slower, and recommends the AMD processors, I find this comment rather brain dead.
  • WaltC - Thursday, May 7, 2020 - link

    One question I had is why AT chose to use the 2600 instead of the 3600...? Makes no sense to me, as the 3600 runs at 65W and the 3600X runs at 95W--just like the 2600--only the 3600 is appreciably faster--but costs the same! 3600 is MIA. No question but that the review benchmarks clearly demonstrate the superiority of the AMD offerings, but we already knew that. I see the omission here--deliberate--of the 3600--while including $425 Intel 6c/12t offerings--as surely an apology for Intel's inability to compete. Such is not needed, really. Apologizing in subtle ways for Intel is, I think, a pretty poor way to write a review on CPUs Intel cannot at the present time compete with--the 3100/3300. Getting right down to it--there was no need to include *any* 6c/12t CPUs here, right? Should have been comparisons only with Intel/AMD 4c/8t cpus, exclusively, imo. Selection of CPUS for *this review* didn't make any objective sense that I could see--beyond the obvious, of course (at least you didn't forget and leave the 3100/3300 out...;))

    I'm guessing the omission of the 3600X has something to do with, at the time I read this, they hadn't even finished all the benchmarks for the 3100. You know, the one in the headline. I don't think it's a conspiracy, just a time constraint.
  • crimson117 - Thursday, May 7, 2020 - link

    They didn't rerun the 2600 for this, they used existing benchmarks.

    They haven't ever benchmarked the 3600 previously, so it's not listed here. They do have the 3700X, however, which is essentially the same performance as a 3600 (except in heavily threaded workloads): https://www.anandtech.com/bench/product/2520?vs=25...
  • MDD1963 - Thursday, May 7, 2020 - link

    I saw other testers on Youtube use the 3600, and, the 3300X was VERY surprisingly close to it's performance...; the 3300X's clearly quite strong threads and lack of inter -CCX -RAM latency issues are reaping benefits!
  • BenSkywalker - Thursday, May 7, 2020 - link

    The choices they use to compare are utterly bizarre. A three and a half year old Intel i7 and last generation Ryzen parts....?

    Legitimately, this review is useless if you are shopping *today*, not just from a team red versus team blue, but where this processor sits in today's market, no clue after reading this. One of my friends was looking for a budget gaming build and I was looking at a 3200G/B450 setup, how does this compare? Instead let's assume people have a time machine and are cross shopping two gen old Ryzen and three green old Intel parts....?

    The charts aren't bad, they are terrible. Have an old i7 in there for reference, ok, put current Ryzen 3 and i3 inn there and if you don't have enough time *only* include them.
  • rabidpeach - Friday, May 8, 2020 - link

    bro, they try to make a point with the reviews. if you want this comparison you use the cpubench feature of this website and compare any chip they tested on any of the tests they have. it's an actual feature not a bug. the point of this article and tests is to show entry level amd 100 price point is as powerful as 3 year old flagship-ish intel for the mainstream. it shows against the zen and zen+ hexacores that it catches up to them in many situations despite lacking in cores. this shows you amd is not just throwing cores at intel anymore. they have ipc too! ok any more spoon-feeding? would you prefer a spork?
