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.
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.

TSMC will do the job for AMD, and in March/April, we should be seeing AMD release the 3700X and/or 3800X that will be hitting the same clock speeds as the 9900k, but with a better IPC.BurntMyBacon - Friday, October 19, 2018 - link
I am certainly happy that AMD regained competitiveness. I grabbed an R7 1700X early on for thread heavy tasks while retaining use of my i7-6700K in a gaming PC. That said, I can't credit them with everything good that comes out of Intel. To say that Intel would not have released an 8 core processor without AMD is probably inaccurate. They haven't released a new architecture since Skylake and they are still on a 14nm class process. They had to come up with some reason for customers to buy new processors rather than sit on older models. Clock speeds kinda worked for Kaby Lake, but they need more for Coffee Lake. Small, fixed function add-ons that only affect a small portion of the market probably weren't enough. A six core chip on the mainstream platform may have been inevitable. Going yet another round without a major architecture update or new process node, it is entirely possible that the 8-core processor on the mainstream platform was also inevitable. I give AMD credit for speeding up the release schedule, though.As to claims that the GF manufacturing is responsible for the entire 1GHz+ frequency deficit, that is only partially true. It is very likely that some inferior characteristics of the node are reducing the potential maximum frequency achievable. However, much of the limitations on frequency also depends on how AMD layed out the nodes. More capacitance on a node makes switching slower. More logic between flip-flops require more switches to resolve before the final result is presented to the flip-flops. There is a trade-off between the number of buffers you can put on a transmission line as reducing input to output capacitance ratios will speed up individual switch speeds, but they will also increase the number of switches that need to occur. Adding more flip-flops increases the depth of the pipeline (think pentium 4) and increases the penalty for branch misses as well as making clock distribution more complicated. These are just a few of the most basic design considerations that can affect maximum attainable frequency that AMD can control.
Consequently, there is no guarantee that AMD will be able to match Intel's clock speeds even on TSMC's 7nm process. Also, given that AMD's current IPC is more similar to Haswell and still behind Skylake, it is not certain that they next processors will have better IPC than Intel either. I very much hope one or the other ends up true, but unrealistic expectations won't help the situation. I'd rather be pleasantly surprised than disappointed. As such, I expect that AMD will remain competitive. I expect that they will close the gaming performance gap until Intel releases a new architecture. I expect that regardless of how AMD's 7nm processors stack against Intel's best performance-wise, I expect that AMD likely bring better value at least until Intel gets their 10nm node fully online.

"To say that Intel would not have released an 8 core processor without AMD is probably inaccurate."It's technically inaccurate to say they would have never made any kind of 8-core processor, sure, but nobody's saying that. That's a straw man. What they are saying is that Intel showed no signs whatsoever of being willing to do it until Ryzen landed at their doorstep.
To be clear, the evidence is years of Intel making physically smaller and smaller quad-core chips for the mainstream market and pocketing the profit margins, followed by a sudden and hastily-rescheduled grab for the "HEDT" desktop market the second Ryzen came out, followed by a rapid succession of "new" CPU lines with ever-increasing core counts.
You're also wrong about AMD's IPC, which is very clearly ahead of Haswell. The evidence is here in this very article where you can see the difference in performance between AMD and Intel is mostly a function of the clock speeds they attain. Ryzen was already above Haswell for the 1000 series (more like Broadwell) and the 2000 series brought surprisingly significant steps.

" What they are saying is that Intel showed no signs whatsoever of being willing to do it until Ryzen landed at their doorstep."Intel released an 8 core what? 3 years before Ryzen. Sure, it was one of their super expensive Extreme procs, but they still did it. They were slowly ramping up cores for the HEDT market, while slowly bringing them to more normal consumer prices. 3 years before Ryzen, you could get a 6 core i7 for $400 or less. A year before that it was like $550-600. A 1-2 years before that, a 6 core would be $1000+. 8 cores were slowly coming.
What Ryzen did was speed up Intel's timeframe. They would have came and came at a price point that normal consumers would be purchasing them. If I had to guess, we're probably 2-3 years ahead of what Intel probably wanted to do.
Now would Ryzen exist, if not for Intel? Core for core, AMD has nothing that can compete with Intel. So...ramp up the core count. We really don't see Intel going away from a unified die design, so that's the best way AMD has to fight Intel. I'm personally surprised AMD didn't push their MCM design years ago. Maybe they didn't want to cannibalize Opteron sales, bad yields, I don't know. Must have been some reason.

Rofl, delusional poster is delusional. And anyone who bought a 2700X sure as shit doesn't need to do anything to "defend their purchase" to themselves hahaha.evernessince - Saturday, October 20, 2018 - link
Got on my level newb. The 9900K is a pittance compared to my Xeon 8176. I hope you realized that was sarcasm and how stupid it is to put people down for wanting value.JoeyJoJo123 - Friday, October 19, 2018 - link
>I think far too much emphasis has been placed on 'value'.Then buy the most expensive thing. There's no real need to read reviews at that point either. You just want the best, money is no object to you, and you don't care, cool. Just go down the line and put the most expensive part for each part of the PC build as you browse through Newegg/Amazon/whatever, and you'll have the best of the best.
For everyone else, where money is a fixed and limited resource, reading reviews MATTERS because we can't afford to buy into something that doesn't perform adequately for the cost investment.
So yes, Anandtech, keep making reviews to be value-oriented. The fools will be departed with their money either way, value-oriented review or not.

Don't be *too* harsh. They're paying the premium to cover lower-level chips which may be barely making back the cost of manufacturing, thus making them a good deal. (Of course, that also helps preserve the monopoly/duopoly by making it harder for others to break in...)Spunjji - Monday, October 22, 2018 - link
Yeah, to be honest the negatives of idiots buying overpriced "prestige" products tend to outweigh the "trickle down" positives for everyone else. See the product history of nVidia for the past 5 years for reference :/
