The AMD Threadripper 2 CPU Review: The 24-Core 2970WX and 12-Core 2920X Tested
by Ian Cutress on October 29, 2018 9:00 AM ESTHEDT 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
Our encoding tests seem to be very memory dependent as the core count is increased, and the increased core-to-core traffic doesn't help either.
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.
Intel wins on compression, AMD wins on decompression.
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.

You would be far to limited with RAM to run 60 VMs on that system. I've got 80 on dual Dell 7425's with dual 24 Core Epycs and 512GB RAM and I'm already getting RAM limited.Again I wouldn't install ESXi on these. Use Win 10 and Workstation for your test/dev and you will have a more agile system. If you don't need it for testing that day you still have Windows. FYI I'm VMware Admin.

All depends...in my home lab environment (which lets me test things at will and do whatever I want as opposed to at work where even the lab is more locked down) . For me, the Threadrippers would be great...but extreme overkill. I actually use old FX8320's which I bought when they were dirt cheap and DDR3 RAM was cheap too. The free version of ESXi works fine for me too. For my purposes the threadrippers would be really cool but more expensive than they would be worth.Icehawk - Monday, October 29, 2018 - link
I would love one of these high cores boxes for our test lab, using W10 and VM on my desktop is very limiting for me (work rig is 7700 & 32gb) - one of these would let me put plenty of resources onboard. Currently my lab runs off a G6 Dell server which is totally fine but if I could get myself a new, personal, lab I'd want a TR rig since it can host a lot more RAM than Intel's option.odrade - Tuesday, October 30, 2018 - link
Hi I completely agree with you.With security enhancement moving to sandbox/VM (Application Guard, Sandboxed Defender in 19H1) virtualization scenario will be more prevalent beyond developper or test scenarios.
One major disappointment is that after 12+ months since GA there is no support for nested virtualization for TR/TR2 ?, Ryzen ? Epyc ?.
This issue seems to be general and not limited to hyper-v (KVM, etc..).
This is strange since EPYC made is way through Azure or Oracle Cloud catalog.
During Ignite 2018 there was a demo with an EPYC box (VM or Server).

You could ask for HyperV over here:https://windowsserver.uservoice.com/forums/295047-...
But such features are often buggy in their initial implementations:

https://www.reddit.com/r/Amd/comments/8ljgph/has_t...
It wouldn't surprise me if they ran into too many problems to want to push out a solution. And Intel has had issues here too - most recently L1 Terminal Fault relating to EPT:

If people buy enough of them, and there is a performance benefit or it otherwise becomes a feature differentiator, support will doubtless be developed. Chicken and egg, I know.

Hi,Thanks four your inputs.
This feature is handy if you want to build advanced lab scenarios while preserving your work environment or avoid the hassle to use dual boot.
Maybe this feature will be enabled with the 2019 Epyc / TR iteration.
And if the the socket and compatibility promises is kept by AMD refreshing
my setup will do it and put those extra pcie lanes to use (upgrading storage as well).
At least the 7mm process will help to kept the power compatibility in line.

For the chart on the last page, the "12-core Battle" it would be interesting to see a "similar price battle" of like the 9900k vs 7820X vs 2920X. I suspect the 9900k would hold up rather well especially once it returns to its SRPmapesdhs - Monday, October 29, 2018 - link
A battle for what? If it's gaming, get the far cheaper 2700X and using the difference to buy a better GPU, giving better gaming results by default (some niche cases at 1080p, but in general the 9900K is a poor value option for gaming, except for those who've gone the NPC route into high refresh displays from which there's no way back, ironic now NVIDIA has decided to move backwards to sub-60Hz 1080p with RTX).Blindsay - Monday, October 29, 2018 - link
Definitely not for gaming lol. It is for a home server (unraid)PeachNCream - Tuesday, October 30, 2018 - link
That's a lot of compute for a home server. Home servers (outside of those used for the development of professional skills or to test software outside of a setting where there are office usage policies) serve very limited useful purposes. They're mainly a solution looking for a problem or just fun to mess around with. I have an old C2D E8400-powered desktop PC with 8GB of RAM that I just recently put online as a local file, media, and internal web server connected via a cheap TPLink PCI (non-e) wifi card. There's nothing that the kids and I have done to it yet that brings it anywhere close to its knees. Even streaming videos from it to three other systems at once is a non-issue and all of those files are stored on a single 1TB 5400 RPM 2.5 inch mechanical HDD. TR is extreme overkill for a toy server at home. Literally any old scavenged desktop or laptop can act as a home server.
