ENGLISH Review + new charts – Intel Core i7 8700K & Intel Core i5 8600K – Coffee Lake + AORUS Z370 Ultra Gaming

Power consumption and temperatures

 
When it comes to power draw and temperature, we can see that Intel really managed to brush up the ole’ 14nm process and they did a mighty fine job too. Because of that, Core i5 8600K takes as much power as 7700K, even if it has 2 extra cores, while Core i7 8700K manages to have a lower power draw compared to Ryzen 5 1600X or Core i7 7800X, even if it has the same number of cores and operates at higher clocks.

A bad news for extreme overclockers – Intel is still using badger fat between the IHS and the die. However, the Coffee Lake CPU’s actually perform pretty well when it comes to core temperature, with 65 oC for 8600K at 4300MHz and 70 oC for 8700K at 4700MHz. Of course, when we bump up the voltage, 8600K can get as hot as 92 oC (5100MHz, 1.35v), which is does not come as a surprise, taking into consideration that we used an air-cooler with a single fan (Noctua NH-D15), with a stock CPU ( no delid), in a pretty hot ambient.

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

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

      Thanks once again

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

      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).

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

      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.
      http://www.tomshardware.co.uk/intel-coffee-lake-i7-8700k-cpu,review-34037-12.html
      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.
