Respected frequencies:
As with every new processor test, our first idea is to check if the advertised frequencies are actually reached. To do so, we will use the Cinebench R23 benchmark. Two cases will be used: a single core bench and a second one in multi core. The idea is to be able to judge the frequency reached and thus, to compare with what was announced by Intel in its slides.
Remember that the Boost frequency in bench is different depending on the processor. Be careful, as Intel points out, when we talk about Max Turbo frequency, it is the maximum frequency that can be reached by one of the processor’s cores executing a single-core workload(mono-thread). This frequency varies according to several factors: the load, the cooling system and therefore the temperature of your processor. This is a notion to keep in mind. Here are the frequencies we should reach on a single core during our run under Cinebench R23.
First step, we leave everything in AUTO in the BIOS except the XMP profile that we load. We do not make any other changes in the BIOS.
Test with i9-13900K:
Here we go with the strongest processor, the i9-13900K. As you can see, we opened several windows to check the frequency and the temperature. The options in our BIOS have been left in AUTO but we will talk about it again in the power consumption section because it has a significant impact on them.
In single core, we can see that the #4 core reaches a frequency of 5500 MHz when it should be at 5.8 GHz. We had already noticed this problem during the test with the 12900K and it does not seem to be resolved yet. We asked EVGA again to find out what the problem was and if there was a particular option to activate. In the BIOS, cores 4 and 5 are set to 5.8 GHz.
When the 24 cores of our i9-13900K are used, the frequency is fixed at 5.5 GHz on the P-Core and at 4.3 GHz on the E-Core. As for the temperature of the hottest P-Core, it is 73°C and on the E-Core 59°C. Let’s not forget that we are equipped with a 480 mm custom cooling loop and that it is currently very cool in the lab.
