We tested a total of 12 CPU’s, starting with 4c/4t models (Core i5 7600K) and up to 10c/20t models (Intel Core i9 7900X). Unfortunately, we did not have a Coffee Lake Core i3 for this review, so we only tested the new Core i5 and Core i7 versions, namely Intel Core i5 8600K and the Intel Core i7 8700K. For those who are curious how high the Core i5 8600K can be overclocked for daily use, we tested it both at stock frequency and overclocked at 5100MHz. Please keep in mind that in our tests COre i5 8600K ran at 4.3GHz on all cores, while Core i7 8700K ran at 4.7GHz on all cores, so testing the Core i7 at 5GHz would have not made too much sense.

For Intel Core i5 7600K and Intel Core i7 7700K we used an AORUS Z270 Gaming 9 motherboard, while the LGA 2066 processors were tested on the MSI X299 Raider. The AMD Ryzen 7 1800X, 1700X, 1700 and Ryzen 5 1600X were tested on the AORUS X370 Gaming 5. For all the CPU’s we used the latest BIOS available on the manufacturer’s website.

We used a GSkill TridentZ 16GB DDR4-3200 CL16 memory kit for all platforms except X299, where we used a GSkill TridentZ RGB 32GB DDR4-3200 CL14 kit. All CPU’s were cooled with a Noctua NH-D15, equipped with a factory fan, powered by a Seasonic P1200 power supply.

We used the best GTX 1080 implementation we had in the lab, namely the Zotac GTX 1080 AMP Extreme, along with the WHQL Forceware 384.94 driver. Windows 10 Pro x64, with all the upgrades up to date, was installed on a 1TB Samsung 850 Evo SSD. We only use updated operating systems, benchmarks and games.

The system was tested on the HSPC Top Deck Station open test bench, with ambient temperatures around 28 oC. We have tried to get a complete set of tests to answer the questions of a wider range of readers. Thus, we have both synthetic tests and real applications, as well as a series of overclockers benchmarks.

    Wow … how nice ! Another day , another tale ! The review in english is nicer because the new graphs used . Thank you for the built effort !

    Thanks for the review and the effort 🙂

    Thank you guys!

  4. squawker a scris pe:

    Very fine review, showing all main aspects of Intel’s last launch.
    Keep up the excellent job!

  5. horse a scris pe:

    thank you very much, would it be possible to run some 4k benchmarks in future reviews ?

    Thanks once again

  6. Monstru Post author a scris pe:

    As more and more people will adopt 4K we will begin using it in our tests.

  7. Cesar a scris pe:

    Why are the temperatures so high on the 8600K? Even though it works with less threads it’s hotter than an 8700K? It doesn’t make any sense. Can someone explain this??

  8. Monstru Post author a scris pe:

    Cesar – the temperatures are lower on 8600K. You are probably looking at the overclocked temperatures (5.1GHz with 1.35v).

  9. J.Nicolae a scris pe:

    Very nice OC at 1.35v. This is the trend, for Intel.

  10. Dench a scris pe:

    thank you! too excited now for that 8700k. wonder how it will do with just a cheap aio considering these went to 5.2/5.3 on air. it’s a brand new day!

    I don’t get it, i checked a few tech websites and numbers are all over the place.
    I want a CPU for content creation, power consumption and render times are important as it will run for hours a day.
    Now, if i look at your charts it seems ryzen 1800x is a bit slower or the same as 8700k but consumes 43W more and gets hotter.
    If i read tomshardware review it seems 1800x, even when overclocked consumes less power than stock 8700k.
    Checked other websites like guru3d,pcworld and the usual tests in handbrake or cinebench put 1700x and 1800x faster than 8700k and some the other way around.
    What is wrong here ? What are the real numbers ?
    Also, what’s the cpu usage in those benchmarks like handbrake or photoshop for different cpu’s ?

    Hi Sierra,

    when it comes to real apps, my advice is to always look at something that is similar to what you will use the CPU for. Because Photoshop is one thing, and 3DSMax is a totally different thing, handbrake is one thing and Premiere is another and so on. So basically, try to find the websites with the test that uses the same tech (encoding engine, rendering engine) as what you will use the CPU for. There are no absolutes here.

    Second, I cannot speak for other websites, I can only speak for our methodology, where the vCore is fixed, RAM runs at the same clocks with same vDDR and so on. And in our tests, 1800X draws more power generally speaking . We test in Prime, and we test using the last version, that also really supports the new AMD architecture.

    As I said, I can only speak for my self, and with our conditions, our settings and our benchmarks these are the results.
