Benchmarking Performance: CPU Legacy Tests
Our legacy tests represent benchmarks that were once at the height of their time. Some of these are industry standard synthetics, and we have data going back over 10 years. All of the data here has been rerun on Windows 10, and we plan to go back several generations of components to see how performance has evolved.
All of our benchmark results can also be found in our benchmark engine, Bench.
3D Particle Movement v1
3DPM is a self-penned benchmark, taking basic 3D movement algorithms used in Brownian Motion simulations and testing them for speed. High floating point performance, MHz and IPC wins in the single thread version, whereas the multithread version has to handle the threads and loves more cores. This is the original version, written in the style of a typical non-computer science student coding up an algorithm for their theoretical problem, and comes without any non-obvious optimizations not already performed by the compiler, such as false sharing.
CineBench 11.5 and 10
Cinebench is a widely known benchmarking tool for measuring performance relative to MAXON's animation software Cinema 4D. Cinebench has been optimized over a decade and focuses on purely CPU horsepower, meaning if there is a discrepancy in pure throughput characteristics, Cinebench is likely to show that discrepancy. Arguably other software doesn't make use of all the tools available, so the real world relevance might purely be academic, but given our large database of data for Cinebench it seems difficult to ignore a small five minute test. We run the modern version 15 in this test, as well as the older 11.5 and 10 due to our back data.
x264 HD 3.0
Similarly, the x264 HD 3.0 package we use here is also kept for historic regressional data. The latest version is 5.0.1, and encodes a 1080p video clip into a high quality x264 file. Version 3.0 only performs the same test on a 720p file, and in most circumstances the software performance hits its limit on high end processors, but still works well for mainstream and low-end. Also, this version only takes a few minutes, whereas the latest can take over 90 minutes to run.

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? :)
