Frequencies reached:
As with every new processor test, our first idea 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.
Remember that the Boost frequency in the bench differs according to the processor. As Intel points out, when we talk about Max Turbo frequency, we are talking about the maximum frequency achievable by one of the processor cores running a single-core (mono-threaded ) 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.
The first step is to select the ‘ Intel Default Settings Performance ‘ profile in the BIOS and activate the XMP I profile. We’ll start by using Intel’s recommendations for this frequency test.
Test with the Core Ultra 9 285K :
Here we go with the beefier of the two processors we received, the Core Ultra 9 285K. As you can see, we’ve opened several windows to check frequencies, temperatures, working cores and power consumption. We’ll start with a Single Core run of Cinebench R23.
We can see that two Performance cores are working alternately, core #0 and core #1, and that they easily reach a frequency of 5700 MHz, as indicated by Intel on its slides. Let’s see what happens when we launch a Multi Core run.
All the cores come into action. The Lion Cove P-Cores reach 5400 MHz and the Skymont E-Cores 4600 MHz. Power consumption is 205 watts, measured at the processor’s two power connectors, and the temperature of the hottest core is 66°C. Let’s get on with our various tests.
Test with the Core Ultra 5 245K :
Let’s move on to the Core Ultra 5 245K. Same principle, we start with a Single Core run.
You can see that one of the cores, Core #1, is running at 5200 MHz. Let’s see what happens when we launch a Multi Core run.
Here we can see that the Lion Cove P-Cores reach 5000 MHz and the Skymont E-Cores 4600 MHz. As far as temperature is concerned, the hottest core is at 54°C.
