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.

Again, AMD's 16-core Zen 2 hardware is breezing past Intel's 18-core Skylake-Refresh family. Even with the added frequency that Cascade Lake will bring, it would be hard to see it able to topple AMD here.

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

As a variable threaded workload, WinRAR also probes memory performance. Both the 3700X and 3800X beat the 3950X here.

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.

AES Encoding

Our AES benchmark seemed a bit off - I would suggest we're being memory limited here but the Ryzen 9 3900X scores a lot higher over the 3950X. More investigation needed.

    That's typically the main problem: minimum frames. Across most benchmarks, Intel can maintain significantly higher minimum frame rates for 144Hz and up. Obviously these metrics are going to be very game-dependent and settings-dependent, but the data are very clear: Intel's higher frequencies give it a significant advantage for minimum frames.

    165hz monitord have existed for a while now. 240hz monitors exist from a number of vendors.

    The reason this is okay is the same reason a lot, or most, car engines advertise a.b liter engines when in reality it’s about a.(b - 0.05). It’s a generally accepted point of court precedents, or maybe in the laws themselves, that you can’t sue for rounding, unless it’s an unreasonable difference from the reality. So if you want to sue AMD, expect to be laughed out of court.

    Problem most probably relies on using High performance profile. When I use it with my 2700X, idle cores are nearly never parked and therefore there's no room for CPU to get Max Turbo on a single core. When I change it to balanced profile, I most idle cores are parked and I get beyon Max Turbo easily - to 4450Mhz. Anandtech should try this.

    I think that's me too nathanddrews. I mostly play WoW and though I haven't seen any actual benchmarks, I'm pretty sure that the 9900KS will outperform the Ryzens. WoW just scales with clock speed past like 4 cores.
  • SRB181 - Friday, November 15, 2019 - link

    I've often wondered what people are looking for when cpu's get to this point. I'm absolutely positive the 9900ks will outperform my current CPU (1950x), but I'm getting 78 fps at 4k60 in WOW set to ultra (10) in the graphics. Not being a jerk, but what exactly do you notice in gameplay with 9900ks that I would notice/see?
  • prophet001 - Monday, November 18, 2019 - link

    I don't have a 9900 I've just seen how WoW behaves with various processors and my own personal experience. I have an old extreme processor x299 chipset with a 1080 GTX. It's highly CPU bound. Even though the processor is 4 core hyper threaded, it won't get past like 45 FPS in Boralus. I know it's not GPU bound because I look at the GPU load in GPU-z and it's like 40% load. I can turn render scale up or down and doesn't really make a difference on my computer.

    That, along with other people's research, leads me to believe that WoW is highly CPU bound but more specifically, core clock speed bound. People that get 5GHz get much more out of the game than people that leave their CPUs at stock clocks.

    prophet001 there must be something else going on with your system, as i type this i am sitting in Boralus harbor, right above where the ship from SW docks looking out towards the mountain, with the ship from SW coming into dock on the left. i am getting a minimum of 65 FPS as i spin in the spot. im running a Asus stix, 1060 gaming, with a i7 5930K @ 4.2 ghz. @ 1080P in other zones, i have seen as high as the 180s.... cpu and GPU utilization is 30-40% and a solid 25% respectfully.
    maybe there is something else with your system that is causing this ?
  • Qasar - Monday, November 18, 2019 - link

    should also mention, thats with pretty much max on the graphics options.

    Wrong answer...;) AMD has only ever said "Max single core boost", emphasis on the word "max," which evidently must be translated for the benefit of people mindlessly trying to pick it apart because the meaning of "max" ever eludes them!...;) Really, I've seen all kinds of stupid come out on this one. AMD does not say, "guaranteed single core boost of 4.7GHz" because it's not guaranteed at all--it is the "max" single-core boost obtainable--not the "only" single-core boost the CPU is capable of! Uh--I mean, I'm embarrassed I actually have to explain this, but *any single-core boost clock above the base clock of the cpu* is a *genuine boost of the core* and "max" of course means only the very maximum single core boost clock obtainable at any given time, depending on all of the attendant conditions! So, take a situation in which all the cores boost to 4.5Ghz, 4.6GHz or 4.3Ghz--every single one of them is providing the advertised single-core boost! And yes, people are indeed seeing 4.7GHz *maximums*--but not all of the time, of course, since "max" doesn't mean "all of the time every time," does it,? In their zeal to defend an otherwise indefendable Intel--people have completely butchered the "max" single core boost concept (well, Intel people have butchered it, I should say..;)). Gee--if the only boost these CPUs ever did was 4.7GHz, then none of them would be "max," would they--they'd be the *normal clock* and the damn CPU would be running at 4.7GHz continuously on all cores!...;) I mean, is it possible for people to wax anymore stupid on this subject than this? "Max" absolutely does not mean "all the time every time"--else "max" would have no meaning at all. Jeez--the stupid is strong @ Intel these days...;) Also, it's interesting to note that with fewer cores and a slower clock AMD processes data *faster* than Intel even though the Intel CPU has more cores and a higher clock--so please, the confusion over "max single core boost clocks" from AMD is just plain dumb, imo. It's plain enough--always has been. Multicore CPUs do not exist merely to see to what GHz a *single core* might reach @ maximum! Jeez--we graduated from single-thread thinking long years ago...;) (Or, rather, some of us did.)
