Intel today announced its flagship Core i9-13900KS desktop processor, a special edition model of the 13900K. The 13900KS is the world’s first desktop processor where he reaches a maximum turbo frequency of 6.0 GHz right out of the box.
The main difference between the 13900K and the 13900KS is that the maximum turbo clock speed has increased by 200MHz, from an already impressive 5.8GHz to 6.0GHz. This is achieved through binned silicon, ensuring that only the best parts are used to build his 13900KS. The 13900KS has a higher base power limit of 150W compared to the 125W of the 13900K and the maximum turbo limit is the same at 253W, but the 13900KS has the Extreme Power Delivery profile which raises the power limit up to 320W to help achieve higher clocks support. speed.
Intel’s claims are perfectly valid, but some conditions are required to reach that clock speed. Intel claims the 6.0GHz figure can be reached without overclocking, which could be maxed out on a standard consumer motherboard using a standard AIO liquid cooler, but Intel’s test video shows the 13900KS was shown to reach that figure only on two P cores. A brief period during the 7-Zip benchmark.
This means that not only are we not hitting 6.0 GHz on all P cores, but the consistency with which we can achieve that number with just two cores varies depending on a number of factors.
Aside from that, the 13900KS is exactly the same as the 13900K in all other specs such as E-core clocks and cache count. However, being binned silicon, the 13900KS should perform better under exotic cooling for extreme overclocking. But if that’s not your use case, you’d be better off using the 13900K instead.
The 13900KS is available now for $699.
