One of the interesting elements on modern processors is encoding performance. This includes encryption/decryption, as well as video transcoding from one video format to another. In the encrypt/decrypt scenario, this remains pertinent to on-the-fly encryption of sensitive data - a process by which more modern devices are leaning to for software security. Video transcoding as a tool to adjust the quality, file size and resolution of a video file has boomed in recent years, such as providing the optimum video for devices before consumption, or for game streamers who are wanting to upload the output from their video camera in real-time. As we move into live 3D video, this task will only get more strenuous, and it turns out that the performance of certain algorithms is a function of the input/output of the content.
All of our benchmark results can also be found in our benchmark engine, Bench.
7-Zip 9.2: link
One of the freeware compression tools that offers good scaling performance between processors is 7-Zip. It runs under an open-source licence, is fast, and easy to use tool for power users. We run the benchmark mode via the command line for four loops and take the output score.
WinRAR 5.40: link
For the 2017 test suite, we move to the latest version of WinRAR in our compression test. WinRAR in some quarters is more user friendly that 7-Zip, hence its inclusion. Rather than use a benchmark mode as we did with 7-Zip, here we take a set of files representative of a generic stack (33 video files in 1.37 GB, 2834 smaller website files in 370 folders in 150 MB) of compressible and incompressible formats. The results shown are the time taken to encode the file. Due to DRAM caching, we run the test 10 times and take the average of the last five runs when the benchmark is in a steady state.
WinRAR requires a good memory base, so we see the quad-channel processors heading up the pack. The high IPC of the Core i7-8700K also does well.
AES Encoding
Algorithms using AES coding have spread far and wide as a ubiquitous tool for encryption. Again, this is another CPU limited test, and modern CPUs have special AES pathways to accelerate their performance. We often see scaling in both frequency and cores with this benchmark. We use the latest version of TrueCrypt and run its benchmark mode over 1GB of in-DRAM data. Results shown are the GB/s average of encryption and decryption.
HandBrake v1.0.2 H264 and HEVC: link
As mentioned above, video transcoding (both encode and decode) is a hot topic in performance metrics as more and more content is being created. First consideration is the standard in which the video is encoded, which can be lossless or lossy, trade performance for file-size, trade quality for file-size, or all of the above can increase encoding rates to help accelerate decoding rates. Alongside Google's favorite codec, VP9, there are two others that are taking hold: H264, the older codec, is practically everywhere and is designed to be optimized for 1080p video, and HEVC (or H265) that is aimed to provide the same quality as H264 but at a lower file-size (or better quality for the same size). HEVC is important as 4K is streamed over the air, meaning less bits need to be transferred for the same quality content.
Handbrake is a favored tool for transcoding, and so our test regime takes care of three areas.
Low Quality/Resolution H264: Here we transcode a 640x266 H264 rip of a 2 hour film, and change the encoding from Main profile to High profile, using the very-fast preset.
High Quality/Resolution H264: A similar test, but this time we take a ten-minute double 4K (3840x4320) file running at 60 Hz and transcode from Main to High, using the very-fast preset.
HEVC Test: Using the same video in HQ, we change the resolution and codec of the original video from 4K60 in H264 into 4K60 HEVC.
For HandBrake video encoding of large frames, there is a bump with the new Ryzen-2000 series processors over the previous generation, however there is still a gap up to the Core i7-8700K. The Core i5-8400 puts in a good showing here, above all but the best Ryzen parts.

Oh, I'm actually curious about your experience with all the systems.I'm still running my i7 2700K at ~4.6Ghz. I do agree I haven't felt that it's a ~2012 CPU and it does everything pretty damn well still, but I'd like to know if you have noticed a difference between the new AMD and your Sandy Bridge. Same for when you assemble the 2700X.
I'm trying to find an excuse to get the 2700X, but I just can't find one, haha.
Cheers!

The the once in a lifetime chance to largely keep your CPU name (2700K => 2700X) should be all the excuse you need.YukaKun - Monday, April 23, 2018 - link
That is so incredibly superficial and dumb... I love it!Cheers!

YukaKun, your 2700K is only at 4.6? Deary me, should be 5.0 and proud, doable with just a basic TRUE and one fan. 8) For reference btw, a 2700K at 5GHz gives the same threaded performance as a 6700K at stock.And I made a typo in my earlier reply, mentioned the wrong XEON model, should have been the 2680 V2.

For daily usage and stability, I found that 4.6Ghz worked best in terms of noise/heat/power ratios.I also did not disable any power saving features, so it does not work unnecessarily when not under heavy load.
I'm using AS5 with a TT Frio (the original one) on top, so it's whisper quiet at 4.6Ghz and I like it like that. When I made it work at 5Ghz, I found I had to have the fans near 100%, so it wasn't something I'd like, TBH.
But, all of this to say: yes, I've done it, but settled with 4.6Ghz.
Cheers!

(an old thread, but in case someone comes across it...)I use dynamic vcore so I still get the clock/voltage drops when idle. I'm using a Corsair H80 with 2x NDS 120mm PWM, so also quiet even at full load; no need for such OTT cooling to handle the load heat, but using an H80 means one can have low noise aswell. An ironic advantage of the lower thermal density of the older process sizes. Modern CPUs with the same TDP dump it out in a smaller area, making it more difficult to keep cool.
Having said that, I've been recently pondering an upgrade to have much better general idle power draw and a decent bump for threaded performance. Considering a Ryzem 5 2600 or 7 2700, but might wait for Zen2, not sure yet.

No, it might have to do with the fact that the 8350K has 1.5x the cache size and beastly per-thread performance that is also sustained at all times—so it doesn't have to switch from a lower-powered state (which the older CPUs were slower at), nor does it taper off as other cores get loaded, which is most noticeable on the the things Samus mentioned, ie. "boot times, app launches and gaming". Boot times and app launches are both essentially single-thread tasks with no prior context, and gaming is where a CPU upgrade like that will improve worst-case scenarios by at least an order of magnitude, which is really what's most noticeable.For instance, if your monitor is 60Hz and your average framerate is 70, you won't notice the difference between 60 and 70—you will only notice the time spent under 60. Even a mildly overclocked 8350K is still the one of best gaming CPUs for this reason, easily rivaling or outperforming previous-gen Ryzens in most cases and often being on par with the much more expensive 8700K where thread count isn't as important as per-thread performance for responsiveness and eliminating stutters. When pushed to or above 5 GHz, I'm reasonably certain it will still give many of the newer, more expensive chips, a run for their money.

Memory prices? Memory prices are still pretty much the way they've always been:-- faster memory costs (a little) more than slower memory
-- larger memory sticks/kits cost (a little) more than smaller sticks/kits
-- last-gen RAM (DDR3) is (very slightly) cheaper than current-gen RAM (DDR4)
I suppose you can wait 5 billion years for the Sun to fade out, at which point all RAM (or whatever has replaced it by then) will have the same cost ($0...since no one will be around to buy or sell it)...but I don't think you need to worry about that.

You didn't write anything about price there... All you've said is that relative pricing for things is the same it has always been, and that's no surprise.The $$$ cost of any give stick is more than it was a year or two ago. 2x8gb DDR4-3200 G.Skill Ripjaws V is $180 on Newegg today. It was $80 two years ago. Clearly not the way they've always been...
