Benchmarking Performance: CPU Office Tests
The office programs we use for benchmarking aren't specific programs per-se, but industry standard tests that hold weight with professionals. The goal of these tests is to use an array of software and techniques that a typical office user might encounter, such as video conferencing, document editing, architectural modelling, and so on and so forth.
All of our benchmark results can also be found in our benchmark engine, Bench.
Chromium Compile (v56)
Our new compilation test uses Windows 10 Pro, VS Community 2015.3 with the Win10 SDK to combile a nightly build of Chromium. We've fixed the test for a build in late March 2017, and we run a fresh full compile in our test. Compilation is the typical example given of a variable threaded workload - some of the compile and linking is linear, whereas other parts are multithreaded.
This is another case where I think our improvised testbed is playing a bigger part, and I'd like to eventually re-run this on my standard testbed. Especially as compiling heavily hits more than just the CPU.
GeekBench4: link
Due to numerous requests, GeekBench 4 is now part of our suite. GB4 is a synthetic test using algorithms often seen in high-performance workloads along with a series of memory focused tests. GB4’s biggest asset is a single-number output which its users seem to love, although it is not always easy to translate that number into real-world performance comparisons.
Like CineBench, the Core i7-8086K does will on the synthetic single threaded test.
PCMark8: link
Despite originally coming out in 2008/2009, Futuremark has maintained PCMark8 to remain relevant in 2017. On the scale of complicated tasks, PCMark focuses more on the low-to-mid range of professional workloads, making it a good indicator for what people consider 'office' work. We run the benchmark from the commandline in 'conventional' mode, meaning C++ over OpenCL, to remove the graphics card from the equation and focus purely on the CPU. PCMark8 offers Home, Work and Creative workloads, with some software tests shared and others unique to each benchmark set.
Here the 8086K does eek out a win over the 8700K, although just barely.

They used to but Intel coolers are so bad that no one used them so instead of making one that was usable for the k CPU's they just stopped including them. At least the other guys include them still and 2 of the 3 are actually usable as coolers. Personally I would rather have some sort of cooler included so at least would be up and running if the high end air or water cooler was om back order or waiting on shipping at least can get the system built and running.Flunk - Monday, June 11, 2018 - link
The ones they sent out with the older -K series processors were a joke. My i5-2500K came with a cooler that couldn't even cool it within Intel's specs running stock in a cold room.mkaibear - Tuesday, June 12, 2018 - link
I'm still using the one which came with my 4790K and it works fine, and the one my 2500K came with also worked fine when I had it, even at 30C ambient temps in the middle of summer.Probably an installation error there Flunk.
(yes, I bought K series processors and never overclocked them, for both of these my intention was to downclock them for reduced heat and noise but never got round to it with the 2500K and the 4790K didn't really downclock very well so I couldn't be bothered!)

Absolutely incorrect. I installed tons of the stock Intel coolers on i5s and i7s and they work as specified for the stock settings of the CPUs plus were normally very quiet.SirMaster - Monday, June 11, 2018 - link
"K" CPUs con't come with heatsinks or fans... Neither does the 8700K or 8600K or 7700K, etc.Matthmaroo - Monday, June 11, 2018 - link
It’s been a while for you , I see - K series cpus have no coolerMemo.Ray - Monday, June 11, 2018 - link
Memo.Ray - Monday, June 11, 2018 - linkAs I mentioned in my comment in the other article a couple of days ago:
Intel managed to give away 8086 "binned" 8700K (AKA 8086K) and still make some money on top of it. win-win situation :D

And you miscalculated because you used the i7 8700 cost not the 8700K cost. They made maybe $300K on them.You know I have never seen anyone complain about say a 40th anniversary version of a car.

If it were more similar to the 4790K with a better thermal design (think devils canyon..) it's something I'd be interested in over the 8700K. It's not tho… and doesn't even come with a specialty cooler that might peak interest.. but rather "NO COOLER" at all.. I dunno..I think Intel missed the boat with this one.

Who *actually* thought, after so many years of Intel not giving coolers with it's "K" model variants, that this one might come with a bundled cooler? :)
