Frequencies reached:
As with every new processor test, our first concern is to check whether the advertised frequencies are actually achieved. To do this, we’re going to use the Cinebench R23 benchmark. Two scenarios will be used: a single-core benchmark and a multi-core benchmark. The idea is to be able to judge the frequency achieved and compare it with what Intel has announced in its slides.
It’s worth remembering that the Boost frequency in the bench is different for each processor. As Intel points out, Max Turbo frequency refers to the maximum frequency attainable by one of the processor cores running a single-core workload. This frequency varies according to several factors: the load, the cooling system and therefore the temperature of your processor. It’s important to keep this in mind, and that’s why we’re reposting the table from the previous page here, before starting our tests.
First, we leave everything in AUTO in the BIOS except the XMP profile, which we load, and we make no other changes in the BIOS.
Testing with the i9-14900K :
Here we go with the toughest of processors, the i9-14900K. As you can see, we opened several windows to check frequency and temperature. The options in our BIOS were left in AUTO, but we’ll come back to this in the power consumption section, as it has a significant impact on consumption.
In single-core mode, cores #4 and #5 can be seen alternating at a frequency of 6000 MHz, in line with Intel’s claims. The temperature of the two cores alternating at 6.0 GHz is 65/66°C. When the 24 cores of our i9-14900K are called upon, the frequency is fixed at 5.7 GHz on the P-Core and 4.4 GHz on the E-Core. The temperature of the hottest P-Core is 90°C, while that of the E-Core is 78°C. Strangely enough, we only reached a frequency of 5.7 GHz for the P-Cores, whereas according to Intel’s documentation, we should be maxing out at 5.7 GHz.
Testing with the i7-14700K :
Here we go with the i7-14700K with the same BIOS settings as above.
In single-core mode, cores #4 and #5 can be seen alternating at a frequency of 5600 MHz, in line with Intel’s claims. The temperature of the two cores alternating at 5.6 GHz is 53/54°C. When the 20 cores of our i9-14700K are called upon, the frequency is fixed at 5.5 GHz on the P-Core and 4.3 GHz on the E-Core. The temperature of the hottest P-Core is 90°C, while that of the E-Core is 75°C.
Testing with the i5-14600K :
Let’s conclude our frequency tests with the i5-14600K model.
Here, there’s no difference between single and multi frequencies, since it will always remain 5.3 GHz. Temperature is around 68°C for P-Core and 57°C for E-Core. Let’s move on to our various tests.
