The actual frequencies:
As with every new processor test, our first idea is to check if the announced frequencies are actually reached. To do this, 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 in order to have a frequency of 4000 MT/s in 14-15-15-35 for our memory kit. We do not make any other changes in the BIOS.
Test with the i5-13600KF:
We continue with the i5-13600K and its 6 P-Core/8E-Core. In single core, we can see that the core #0 reaches a frequency of 5100 MHz but strangely the other cores also remain at this frequency. It seems that it is the AUTO settings of our BIOS that remove the limits of Intel since the temperature is correct. The temperature of the requested core is 49°C.
When all the cores are used, the frequency is always 5.1 GHz for the P-Core and 3.9 GHz for the E-Core. Finally, we will not complain since the temperatures are excellent with the hottest P-Core at 73°C and the E-Core at 60°C.
Now that we know our processor is fully operational, let’s see how the performance compares to the Z790 chipset.
