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.7-Zip 1805 Compression7-Zip 1805 Decompression7-Zip 1805 Combined

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.

WinRAR 5.60b3

One of our closes tests between an overclocked 2600K and the 7700K at stock is WinRAR. It's a variable threaded test, and doesn't seem to take advantage of any of the newer instructions offered by the 7700K. However, the more cores of the 9700K over having real threads shows a big bonus, as well as the upgraded DRAM.

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.

    You don't need to buy a new computer every year and with an intelligently made upfront investment you can potentially keep your desktop, with minimal or zero hardware upgrades, for a *very* long time

    /news at 11

    If there is any argument that supports this its Intel's consumer/prosumer HEDT platforms.

    The X99 was compelling over X58. The x299 is not even remotely compelling. I still have my old X99/ i7-5930k (6 core 40 lane PCIe3). its still fantastic, but thats at least partially because I bit the bullet and invested in a good motherboard and GPU at the time. All modern games still play fantastically and it can handle absolutely anything I throw at it.

    More a statement of "future proofing" than inherent performance.

    It's always disappointing to see heavily GPU bottlenecked benchmarks in articles like these, without a clear warning that they are totally irrelevant to the question at hand.

    It also feeds into the false narrative that what resolution you play at matters for CPU benchmarks. What matters a lot more is what GAME you're playing, and these tests never benchmark the actually CPU bound multiplayer games that people are playing, because benchmarking those is Hard.

    So if you're a gamer, there is STILL no reason for you to upgrade.

    I have a 2600K system with ASRock mobo

    Now that there is so much hype about the Ryzen 3, is that my best option if I wanted to upgrade? I guess I would need a new mobo and memory in addition to the CPU. Otherwise I can use the same SSD etc.

    Still running my 3770 at stock clocks - "not a worry in the world, cold beer in my hand".

    Added an SSD and upgraded to a 1070 from the original GPU, . Best machine I've ever had.

    I was running my X1950XT AIW at wonder level overclocks with a Pentium M overclocked, and crushing Athlon 64 users.

    It would have been really interesting to see that 7700K with DDR3. I run my 7700K @ 5Ghz with DDR3-2100 CL10 on a GA-Z170-HD3. Sadly the power delivery system on my board is at it's limits. :-(

    But still a massive upgrade from a FX-8320e and MSI 970 mobo that I had before.

    I forgot to add that it's 32GB(8GB x 4) G.Skill CL9 1866 1.5V that runs at 2100 CL10 at 1.5V but I have to give up 1T command rate.

    The GPU that I carried over is the Fury X. Bios modded of course so it's undervolted, underclocked and the HBM timings tightened. Whips the stock config.

    The GPU is next up for upgrading, but I'm holding out for Navi with hardware RT and hopefully HBM. Once you get a taste of the low latency it's hard to go back.

    OpenCL memory bandwidth for my Fury X punches over 320GB/s with single digit latency. The iGPU in my 7700K, is around 12-14GB/s and the latency is... -_-

    There are several things about this article I dont like

    1. In the Game Tests, i actually dont care if one CPU is 50 Percent better when one shows 10 FPS and the other 15. Also I don’t care if it is 200 or 300 fps. So I would change to scale into a simple metric and that is: is it fun to play or not.

    2. Development is not mentioned: The Core Wars has just started and the monopoly of intel is over. Why should we invest in new processors when competition has just begun. I predict price per performance will fall faster in the next years than it did in the previous 10 years. So buying now is buying into an overpriced and fast developing marked.

    3. There is no Discussion if one should buy a used 2600k system today. I bought one a few weeks ago. It was 170 USD, has 16 GB of Ram and a gtx760. It plays all the games I throw at it and does the encoding of some videos I take in classes every week. Also I modified its cooler so that it runs very very silent. Using this system is a dream! Of course one could invest several times as much for a new system that is twice as fast in benchmarks but for now id rather save a few hundred bucks and invest when the competition becomes stagnant again or when some software I use really demands for it because of new instructions.

    Great write-up! Love my 2600k still to this day and solid at 4.6GHz on air the whole time! I do see an upgrade this year though. She's been a beast!! Never thought the 300A Celeron OC to 450 would get beat! haha
  • SirBlot - Monday, July 25, 2022 - link

    I get 60fps SotTR cpu game and render with rtx 3060ti with ray tracing on medium and everything else ultra. 2600k @4.2
