Power, Temps, Overclocking

Information technology's important to mensurate power consumption with something that stresses all cores and I've institute Corona works well for providing accurate results, so these load figures are based on the Corona criterion after a unmarried pass and I'm reporting the maximum logged issue. This is full arrangement draw and I'm using a Cabac Power-Mate to measure from the wall draw.

When it comes to power draw the Core i7-8700K is certainly on the loftier side only it's not as farthermost as what we saw from the Skylake-X CPUs. The 7800X for example was not only slower in every single test but it besides pushed total organisation draw 17% higher. Compared to the 1800X, the 8700K did increase system consumption past 18% so Intel isn't quite every bit efficient considering they've had to increase frequency quite aggressively in order to keep pace with AMD's 8-core Ryzen 7 processors.

Still overall I'm impressed with what Intel has been able to achieve here, the 8700K looks very solid all-round. With that let's see how this affair overclocks...

Overclocking

If you delided the 7700K you could become 5.0 GHz out of it, maybe 5.i GHz. With very little effort I pushed my 8700K chip to 5.two GHz and here it was 100% stable. I could even boot into WIndows at v.3 GHz and run a few tests but it will crave effectively voltage tuning for 100% stability and we didn't have as well much time to play around with overclocking and then I settled for five.2 GHz.

Still, this is a mighty impressive result and it means the 8700K is at present able to match the multi-core score of the 1800X in Cinebench R15 while devastating the single thread effect. That said, you can of course overclock the 1800X as well and this allows information technology to remain alee in productivity workloads.

Speaking of which, this is how the overclocks change Corona'due south results. The 1800X was only two seconds quicker to completion than the 8700K at 5.2 GHz. The overclock meant that the 8700K was able to complete the chore 15% faster. That said, the 1800X saw a 20% improvement once overclocked.

The Ryzen 7 1800X overclock increased system power draw past a whopping 42% and this was the verbal same increase seen from the 8700K besides, though it never provided anywhere virtually that kind of functioning proceeds and then as usual efficiency goes out the window when you overclock.

Temps

I haven't had a adventure to build my new Core i7-8700K examination system all the same merely I will in the next week or then and that will be my new GPU testing machine. For at present I'm using the DeepCool Captain 240EX RGB, it's all all-in-one liquid libation with a 240mm radiator. It's a decent solution though the Noctua NH-D15 air-cooler has been reported to deliver slightly better temperatures on an overclocked 7700K for example. That said, the D15 is most as good every bit air-coolers get.

Anyway, with a room temperature of 21 degrees the 8700K idled at 25 degrees. Stressing both the CPU and FPU caused the temps to hit 84 degrees while only stressing the CPU saw temps max out at 60 degrees.

Once overclocked to v.two GHz, we reached inside six degrees of the TjMAX while running the CPU stress examination, peaking at 97 degrees briefly. Plain a delid would help tremendously for those seeking farthermost overclocks, and/or a more extreme cooling solution.
