Power, Temps, Overclocking

It's important to mensurate ability consumption with something that stresses all cores and I've found Corona works well for providing accurate results, then these load figures are based on the Corona benchmark subsequently a single pass and I'm reporting the maximum logged event. This is full organisation draw and I'grand using a Cabac Power-Mate to measure from the wall draw.

When information technology comes to power draw the Core i7-8700K is certainly on the loftier side just it's not as extreme equally what we saw from the Skylake-X CPUs. The 7800X for case was not only slower in every single test simply information technology also pushed total system draw 17% higher. Compared to the 1800X, the 8700K did increase organisation consumption past xviii% so Intel isn't quite as efficient because they've had to increase frequency quite aggressively in order to continue pace with AMD's 8-cadre Ryzen 7 processors.

Still overall I'm impressed with what Intel has been able to reach hither, the 8700K looks very solid all-round. With that permit's run into how this matter overclocks...

Overclocking

If you lot delided the 7700K you could get 5.0 GHz out of it, maybe 5.1 GHz. With very picayune endeavour I pushed my 8700K flake to 5.2 GHz and hither it was 100% stable. I could even boot into WIndows at 5.3 GHz and run a few tests but information technology will require 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 5.2 GHz.

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

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

The Ryzen vii 1800X overclock increased arrangement ability depict by a whopping 42% and this was the verbal same increase seen from the 8700K likewise, though information technology never provided anywhere near that kind of performance proceeds so as usual efficiency goes out the window when you overclock.

Temps

I haven't had a take chances to build my new Core i7-8700K exam organization all the same but I will in the adjacent week or so and that will be my new GPU testing machine. For now I'm using the DeepCool Helm 240EX RGB, information technology'due south all all-in-1 liquid libation with a 240mm radiator. It's a decent solution though the Noctua NH-D15 air-libation has been reported to evangelize slightly better temperatures on an overclocked 7700K for case. That said, the D15 is near equally 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 acquired the temps to hit 84 degrees while simply stressing the CPU saw temps max out at 60 degrees.

Once overclocked to v.2 GHz, nosotros reached within half dozen degrees of the TjMAX while running the CPU stress examination, peaking at 97 degrees briefly. Manifestly a delid would assistance tremendously for those seeking extreme overclocks, and/or a more extreme cooling solution.
