Thank you RealSteelH6,
it's good to add this CPU-RAM configuration, I myself want to run similar build but with i3-8100 and 64GB.

Code:

It surprises me to see i5 8600K and i7 8700K so close in decompression.

Get down get down get down get it on show love and give it up
What are you waiting on?

I'm also surprised, it almost looks like that HT has zero benefits there and the score just is lower because of the slower clock speed.

As far as I understand those additional 6 threads should have delivered ... something, perhaps the 32MB dictionary is the reason, most of the RAM accesses are outside the LLC (last level cache) i.e. non-cached which stalls the process.
In the i7-8700K the memory usage is 2648MB whereas in your case 1324MB, maybe the 6 virtual threads are accessing RAM without cache help.

By the way, I wrote to Igor asking him to consider adding third value, namely, MAX of the runs, to no avail:

The 8600K was benched with 18.05, which is way faster at decompression than 16.04. Everyone needs to be on the same version for the comparison to be relevant.

Number of threads also changes how memory is used because 7-Zip's bench is essentially spawning another test, using it's own dictionary allocation, with each thread.

Here are my numbers but this is with an early segfault bugged R7 that is getting sent to AMD today so Im sure there were segfaults during the benchmark. Ill be installing my 2700x and submit that later tonight after the benchmark and of course dealing with my memory timings on the new CPU.

Just ran the bench on my primary signature system with both 16.04 and 18.05 to illustrate the differential:

16.04


18.05

Many thanks Blameless, didn't notice neither the version difference nor that Igor did make major improvements, for so long the 7-zip decompression stayed the same.
