As with the graphics cards, the power consumption is the measure of what you have to dissipate in the end also in waste heat. However, we want to go into this in more detail in a while. First, let's look at what the CPU as such picks up via the package. Although the differences between the different model series of the manufacturers are serious in terms of the measured values and the respective design, with the Intel Core i7-8700 we have chosen a CPU in the test, which is already available for most users as extreme case, at least in the "normal" consumer environment.
Prime95 with AVX and "Small FFTs" wins from powerMAX with AVX and the FPU test from Aida64. At least when it is up to the power.
This order remains the same even for the simultaneous measurement of the overall system, at least among the front-runners. Slight shifts with midfield result from different loads (e.g. memory) and the slightly different voltage transformer losses due to a different load change behavior. However, these shifts are rather marginal.
Nevertheless, we have re-listed this difference between the total power consumption and the individually recorded values, because there are already some serious differences. After all, these tests can be used to estimate how much additional waste heat is generated in the system, which cannot be dissipated directly from THE CPU cooling. This is especially important to know if you want to design a water-cooled system and think about the housing ventilation and the test that is most suitable for exploring the maximum.
