Benchmarking Performance: CPU Encoding Tests
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
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.
Again, trading blows with the 8700K, but falling behind a little bit.
WinRAR 5.40
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.
The 8086K takes another benchmark sitting behind the 8700K.
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.
Under AES encoding we get literally identical results.
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.

It seems like the only good reason to buy this processor would be for the preferential binning - it's kind of like a manufacturer official version of Silicon Lottery.xpto - Thursday, June 14, 2018 - link

well i know and few more that anatech are and clear long time amd support and cant make test without raise amd gpus and cpus someway better.sad...
but we are not idiots
its clear that both 6-core cpus 870k0 and 8086 are much better cpus than amds 8-core ryzen 2700x. that is clear fact
2700x is 8-core and still loose 3dmarks what is historical.. bcoz never bfore cpu that own more cores LOOSE cpu wich have less them.
its tell clear that ryzen 2700x is weak and also mem problem show it.
2700x cant handle high timing and hertz,
2700x is better and really shod be for mathematic apz,but as i say ITS 8-CORE CPU.
still it loose many test.
and for thouse importants games and 3dmarks its loose and clear.
when intels ALSO 8-core cpu guess 9700k release we really see how bad 2700z is.
i can say that 8-core 2700x loose clear for intels 9700k 8-core cpu.
ok..then 6700k vs 8086 cpu
well its clear that 8086 is better than 8700k,bcoz 8086 is hand picket cpus and oc'd better than 8700k.
so its mean 8086 ov'c higher,running lower heat ...exmaple all 8086 ov'd easily 5ghz, many 8700k not. only best.. and i took 24/7 use.
sure if you get good 8700k its different,but if different is example anatech saying 75$ that i can get good cpu i pay it for joy!
if you want best gaming rig buy:
asus hero x
2x8gb 4000mhz cl17 mem
8086 or 8700k cpu and ocäd it about 5ghz
buy more nvidia gtx 1080 ti
then u have gaming rig that amd cant beat near 2 years...think about it...
gtx 1080 ti is old shit and amd vega only few month old still no chance.

I wasnt expecting much out of the 8086k over the 8700k... but this is truely underwhelming. Only a single core turbo boost? I was expecting all the boost tiers to be higher. And same tdp....so there goes it doing anything more at stock.I wasnt going to buy one anyway....so i guess it doesnt matter. I completely agree that intel could have and should have done more.
