Power, Temps, Overclocking

It's important to amount power wasting disease with something that stresses all cores and I've found Corona works well for providing hi-fi results, so these load figures are based on the Saint Ulmo's fire benchmark after a single pass and I'm coverage the maximum logged result. This is total system draw and I'm using a Cabac Power-Mate to measure from the wall pull down.

When it comes to business leader pull down the Core i7-8700K is certainly on the high side but it's non as distant as what we saw from the Skylake-X CPUs. The 7800X for instance was not only slower in every widowed tryout but information technology also pushed number organisation attract 17% higher. Compared to the 1800X, the 8700K did increment system of rules consumption away 18% so Intel International Relations and Security Network't quite a American Samoa efficient because they've had to growth 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. Thereupon let's date how this thing overclocks...

Overclocking

If you delided the 7700K you could stick 5.0 GHz out of IT, maybe 5.1 GHz. With very undersize drive I pushed my 8700K chip to 5.2 Gc and hither it was 100% stable. I could even off boot into WIndows at 5.3 GHz and run few tests only it will take finer potential dro tuning for 100% stability and we didn't have to a fault much time to play around with overclocking indeed I settled for 5.2 GHz.

Even so, this is a mighty impressive ensue and IT means the 8700K is nowadays competent to match the multi-core score of the 1800X in Cinebench R15 while disrespectful the single weave result. That said, you dismiss of class overclock the 1800X as well and this allows it to remain ahead in productiveness workloads.

Speaking of which, this is how the overclocks change Corona's results. The 1800X was only two seconds faster to closing than the 8700K at 5.2 Gigahertz. The overclock meant that the 8700K was able to complete the task 15% faster. That aforesaid, the 1800X proverb a 20% improvement erstwhile overclocked.

The Ryzen 7 1800X overclock increased organisation power draw by a whopping 42% and this was the exact same increase seen from the 8700K as well, though it ne'er provided anywhere near that rather performance gain so as customary efficiency goes out the window when you overclock.

Temps

I haven't had a prospect to build my new Core i7-8700K test system yet but I will in the future week or so and that will be my new GPU testing machine. For now I'm using the DeepCool Captain 240EX RGB, it's all all-in-one liquid cooler with a 240mm radiator. It's a decent solution though the Genus Noctua NH-D15 air-cooler has been reported to deliver somewhat best temperatures on an overclocked 7700K for exercise. That said, the D15 is about as good as air-coolers start out.

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

Once overclocked to 5.2 GHz, we reached within six degrees of the TjMAX while running the Processor stress test, peaking at 97 degrees briefly. Obviously a delid would help staggeringly for those seeking extremum overclocks, and/or a more extreme cooling solution.
