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.

So what happened here? It looks like Intel's play with frequencies made this throttle more often. At least that the only explanation I can find for 8700k ending up better in so many tests.Tkan215215 - Monday, June 11, 2018 - link
As always its called milking and wallet ripper they know people still Buy them anywaybug77 - Monday, June 11, 2018 - link
I wasn't expecting this to be a cost-effective part, but rather a collector-oriented one.But mostly worse than a standard part is surely unexpected.

I don't think it's worse as much as the silicon lottery exists regardless of it. In other words, even among speed binned parts some OC better than others. And that's true for both the 8086K, the 8700K or any others.just4U - Wednesday, June 13, 2018 - link
I agree bug,I'd be very interested in this processor if it brought something to the table to justify it's cost. The 4790K did with a better thermal design. They could have added a kick ass cooler, or a factory delid and redo for better thermals. Something .. anything besides a small bump in clocks.

It might be milking, but I kind of have a hard time believing that. They're only making 50,000 of them, and only at about a 21% markup over the 8700k. But they're flat out giving away 16% of the chips. I doubt Intel is going to milk much money beyond their regular business from this. It's the companies 50th anniversary year, so I'm going to guess it's just positive fanfare and a collector's item related to that and it happening to be an anniversary for a well known processor at the same time.Old_Fogie_Late_Bloomer - Monday, June 11, 2018 - link
I enjoy hating Intel as much as the next guy but this is a good point.Revenue from 41,914 8086Ks: $17,813,450
Revenue from 50,000 8700Ks: $17,500,000 (at $350 apiece)
The remaining $313,450 doesn't really feel like a lot of money when you factor in binning the chips and dealing with all the other overhead of the promotion, especially since Intel isn't getting all of that money anyway.

This was actually not the revenue but the PROFIT you blind people with easily effed brains. The production cost for this chip was probably less then 20 bucks. The processor in your phone is probably more hi-tech, has more transistors, more cores, and was made on more advances factories with 10nm litho being all sold below $25.mkaibear - Tuesday, June 12, 2018 - link
What are you smoking?His maths is bang on, although he neglects the cut the retailer will be taking off the top for that. They aren't making that much profit off each chip.
SanX - Tuesday, June 12, 2018 - link
They aren't making that much profit off each chip? If they aren't making huge profits then all mobile chip factories lose money by selling the same transistor count processors like the one in Apple or Samsung phones for just $25
