This CPU, like the Core i7-7000, does not have an open multiplier compared to the Core i5-7600K and also has a significantly lower base clock. Also with this CPU, an overclocking over an increase BCLK by certain factory specifications was made uninteresting. The few MHz that you could possibly gain are not worth all the effort in the end.
If the ex-factory fixed base clock is quite a tranquil 3.5 GHz. so the CPU manages at extreme loads on all cores, at least to 3.9 GHz Turbo Core per core. Let's look at how the CPU behaves under different loads.
Core Voltages (Vcore)
However, before we get to the power consumption and the resulting temperatures by converting it into waste heat, we first compare the core voltage (Vcore), which should not be confused with the VID adjustable in the BIOS (which is always higher). What we measure here are the real voltage values provided by the converters for the CPU.
Power consumption is low enough to provide the same voltages for both gaming and FPU torture loop doe. Only Intel's Power Thermal Utility manages to reduce the voltage in which the power dissipation is at least slightly more concentrated.
Normal Load: Gaming
We determine the gaming load as usual and measure an average of 42 to 43 watts for the entire CPU, which is a good value. You can also see that only up to 32 watts are required for the computing units, because the difference to the total power consumption is distributed over the rest of the CPU.
In contrast to the increase in temperatures, we have already seen a smaller increase in power consumption values, so that the losses due to leakage currents after heating can increase to up to 1.4 watts.
The temperatures rise to varying degrees depending on the position of the respective readout sensor, but stabilize already after approx. 18 minutes. Interestingly, for the first time, the value returned as a GPU diode is the highest at the end.
Heavy Load: Torture (Floating Point Unit)
At the next run we let the CPU calculate again, so that a measurably higher power consumption of up to 49 watts results. Losses from leakage currents as warming rise also remain in the same frame as gaming. The values for the IA Cores and the rest are, as usual, much lower.
Temperatures are also rising significantly, and once again everything already written for the gaming scenario applies. With up to 61°C, however, everything is still very easy to shear and can be cooled even with simpler air coolers.
Maximum Load: Intel Power Thermal Utility (100%)
The last time we start PTU with 100% load to push the CPU to the edge of the given possibilities. Here, too, there is a significant increase, as 72 to 73 watts of power are still absorbed (and converted into heat). Interestingly, the further losses due to higher leakage currents after heating do not exceed the 1.5 watt limit compared to the cold CPU.
With the temperatures, we can see that the CPU diode, which was once so hot, now remains significantly cooler and even significantly below the average temperature for all cores, while the readout value for the CPU package, as always, flanks the peak values.
Intermediate conclusion
The smallest CPU in the test is the most economical and efficient in proportion, which is certainly not only due to the chip quality. The chosen clock is much closer to the so-called sweet spot of the CPU, which always recommends the four-core when it comes to smaller and perhaps also difficult to cool projects, in which the power dissipation of the components is kept as low as possible Should.
