The Intel Xeon W-3175X Review: 28 Unlocked Cores, $2999

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.
For our graphs, some of them have two values: a regular value in orange, and one in red called 'Intel Spec'. ASUS offers the option to 'open up' the power and current limits of the chip, so the CPU is still running at the same frequency but is not throttled. Despite Intel saying that they recommend 'Intel Spec', the system they sent to us to test was actually set up with the power limits opened up, and the results they provided for us to compare to internally also correlated with that setting. As a result, we're providing both sets results for our CPU tests.
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.

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.

Future bought the bulk of Purch not too long ago, but if it's same old same old, then I agree.Cooe - Wednesday, January 30, 2019 - link
Until these benches are all repeated in Linux all of these results are wortheless. Nobody would buy these CPU's for a Windows machine, and the 2990WX is totally borked by running in Windows as well.WasHopingForAnHonestReview - Wednesday, January 30, 2019 - link
True but the 2990WX is 1300$ cheaper and gives roughly the same performance. No one is going to buy this intel chip unless they have money to burn.maroon1 - Wednesday, January 30, 2019 - link
Same performance ?! Did you look a the benchmarks ?! w-3175x is cleary winning in majority of benchmarks (and some benchmarks should big advantage for w-3175x)I agree about price, but performance is not same
MattZN - Wednesday, January 30, 2019 - link
It depends on what precise application(s) you are running. But yes, the performance is about the same. Those benchmarks are pretty broken for a host of reasons... windows scheduler nonwithstanding, looking at a bunch of benchmarks doesn't really tell you a whole lot about how a machine will work in your actual environment.All that matters is whether the machine's performance affects your workflow in a noticeable way or not. Nobody is going to justify buying something like this if all they get out of it is a 15 minute faster encoding on a 2-hour job. Imagine that! Let alone a few seconds here and there, or a slightly slower or faster frame rate. For longer jobs you'll notice if something takes half the time. You won't notice if something is 20% slower or 20% faster. You just won't.
Many video encoding workloads are GPU accelerated, for example. Many are run as overnight batches, for example. If you go through all the benchmarks in this article, almost none of them are even remotely relevant to actual use cases. The Blender one maybe, Handbrake, and Adobe Premier and that's just about it. And surprise, surprise, the TR2950X or TR2990WX actually wins some of those.
For example, does anyone actually care how fast 7-zip runs? I sure as heck don't! I zip something up, it's well neigh instantaneous on just about any machine. Encryption? Nobody cares, it isn't a use case that anyone will notice. Office applications like spreadsheets? Come on... that's ridiculous. A 2-core mobile CPU can update a spreadsheet just as fast as one of these behemoths.

It does kinda matter for server-level ctivities. Say you have a SQL dump that you want to backup without using too much transfer. You can't run nightly backups until it's done. Even compressed it's 4GB. I use xz but it's essentially the same as 7-zip. More threads and faster threads can make a significant difference in run time, and in turn this impacts when you can backup or how much data you can handle on the system.I think you may be mistaken about the 20% difference if it effectively means you have to pay 20% more people. The question, as always, is is the price and other costs associated worth the improvement.

Why would you do any of that on this chip that sucks 600W, for all of your listed task a dedicated server chip would be better, you run them in batches over night as said, so the speed really does not matter at that point.This chip here is intended as a workstation work horse, and yes, with the price of the single chip and the expensive motherboards (which we still don't know if they will be available to the end-user directly) makes this an quite pointless platform, except if you are running Adobe Premiere 24/7.
For everything else you are better of with the cheaper AMD and Intel solutions, and you can get multiple systems of those for the price of one of these 3175X systems, split the work load or make them work together and they deliver faster results.

Not everyone has access to full blown server rendering farms. A lot of remote workers or freelancers would render with this "behemoth". Not everyone can blow 10,000 USD to have a bunch of EPYC servers just standing by.Still.. This thing doesnt seem THAT good compared to AMD's (both price, performance and power usage) to justify it.
only the AVX512 benches I guess.
But then.. Zen2 is supposed to double the output of AVX if I remember correctly.
WasHopingForAnHonestReview - Thursday, January 31, 2019 - link
7zip and some specific renders... The time saving isnt much. Its not even close to make this a worthwhile buy. When you take into account the windows scheduler bug fix coming... The amd TR for $1300 is still the obvious winner.eddman - Wednesday, January 30, 2019 - link
"No one is going to buy this intel chip unless they have money to burn."So it's not "No one" then.
I suppose 3D modeling and rendering studios or individuals that have lots of customers will probably be quite ok with buying these. That price is nothing compared to their income. They probably care more about reducing rendering time than saving a few thousand dollars, which they can recoup in probably a week or two.
