The Intel Core i9-9900KS Review: The 5 GHz Consumer Special
by Dr. Ian Cutress on October 31, 2019 10:45 AM ESTCPU 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
The 9900KS performed worse than our 9900K in our Handbrake tests, and we're not entirely sure why. It might be related to the regression we saw with DigiCortex.
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.
Both the 9900KS settings perform identically here, however the Compression test shows a performance regression compared to the standard 9900K. It does make me wonder if there are additional differences between the two chips (such as an internal clock).
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.

Shame you don't complain so much about AMD CPUs unable to reach promised boost clocks as much as you care about Intel power consumption. We get it, you are poor, you could finally afford 8 cores thanks to AMD yet loosing to Skylake refresh crippled by security patches so venting your frustration here. Difficult time to be an AMD fan, especially after the first gen threadripper support drop fiasco, suddenly a new socket and no backward compatibility is not an issue. Don't hate things just because you can't afford them. Fridays for future is up today again, vent your problems there, thanks. Anyway, bye, a private plane is waiting, gonna have a pizza for dinner in Italy to piss off Greta because I can.jonbar - Friday, November 8, 2019 - link
"Skylake refresh crippled by security patches" - you must be kidding, right? It shouldn't have those security holes. Please stop talking shit about poor because people here talk about optimization - the best for the least money at a price point. And please stop bashing AMD's ryzen - it's not bulldozer, without ryzen this shit here would be sold as "Intel i11 Unobtanium Edition" for 1k$ and you, rich boy, would have 6 cores or more only on LGA 2011.Nobody hates a product - I don't like Intel practices - 5% increase per generation to the point. Where my i7 3840qm is 10-15% slower than 7700hq with a 4! generations gap.
Speaking about private planes - nobody gives 1 cent on rich boys approach on tech at this level because, while you can afford stupid - the rest of us have to be smart. Now you can fly eat your pizza:)

wow maxiking... resorting to insults and name calling still ?? still believing all the intel bs ?? still believe intels bs about how much power their cpus use ?? talking like you have money is supposed to impress people ?? good for you.. nice to see you are also arrogant rich spoiled bratMaxiking - Friday, November 8, 2019 - link
How dare you? Where did I name call anyone? If someone is fat and I call them fat or if they smell and I tell them so, it is not an insult, it is called stating a fact.I see you still do not get the TDP does not mean power consumption, it is even stated and explained in the review.
If I were you, I would be more concerned about 1700x, 1800x, 2700x, 3900x TDPs and AMD misleading marketing about boost frequencies because there have been so far 3 bios patches which were supposed to fix the issue and guess what. Nothing has changed. People have to use a makeshift custom power profile created by a geek in order to get closer to the promised boost clocks.
Typical AMD, I give it 3 months till he starts fixing their awful gpu drivers aswell.

calling people poor.. among many other things in previous posts by you.. and yes it is an unsult to call some one fat.. or they smell.. but, i bet you do that because either your selfesteem, and self worth is so low, you have to say things like that to make your self feel better..yet you still cry about ryzen and the clock speeds.. but yet. you STILL refuse to admit the fraud intel calls is tdp spec ?? so what ever maxipadking . go back to your cave...
Maxiking - Sunday, November 10, 2019 - link
Yeah, my self esteem is so low that I regularly visit Mercedes and BMW showrooms only to tell them how they cars are overpriced and my Dacia is cheaper and can perform the same and consuming less gass like you do. If Intel TDP is fraud, so does is AMD's one and their promised boost clocks and video on youtube where they promise you can overclock chips even further with sufficient cooling. What do they mean by that? Ay, and what about the bulldozer fraud?Korguz - Sunday, November 10, 2019 - link
yea sure you do, your the one who is probably poor... you are becoming the worst intel shill on here now.... all you EVER do is talk. if you are so sure amd is committing fraud as you claim, then put your supposed money where your mouth is, and take AMD to court,m or shut upMaxiking - Monday, November 11, 2019 - link
Again, it is you, you and only you perpetuating lies. I never come here first talking **********, I only reply to amdfanboys comments.I do not own any AMD cpu, I do not buy subpar products so I can not take them to court.
Anyway, if you are so sure about Intel wrongdoings, take them to the court. EZ.
Unfortunately for you, it is AMD who lost at court and got caught misleading about that parody on cpu called bulldozer. Claiming to possess 2 times more cores than they actually had.
This is your AMD marketing in a nutshell

QQ more. Deal with it.
Korguz - Monday, November 11, 2019 - link
maxipadking.. you are so full of it... what about the intel lies about its 10nm nodes for the last what.. 6 years being on track ?? what about the lies about their not doing anything wrong to prevent amd feom selling its products ?? among various other things over the years that you so easily for get... you never come here 1st ?? BS actually.. you DO buy sub par products.. intel is sub par now.. but in your intel blindness.. you just dont see it... intels marking has been worse over the years then amd.. deal with that.keep QQing more about it... your good at it..

Maxiking, this is a tech site, not your favourite social network for trolling. Your shameless trolling should be punishable with a ban.
