unsurprisingly the best of Raptor Lake

The chip binning of Raptor Lake processors is coming to an end with the Core i9-13900KS. These processors pre-selected by Intel logically display the best SP scores: average of 108.1, against 101.1 for the previous champion, the Core i9-13900KF.

For several weeks now, Xaver Amberger from Igor’s LAB has been carrying out chip binning on Raptor Lake processors ; a sort that consists of comparing the SP score (Silicon Prediction) of hundreds of chips by installing them on an Asus motherboard. The previous review involved almost 500 processors, from Core i5-13600K to Core i9-13900K. The winner of this first round was the Core i9-13900KF, with an average SP of 101.1. However, a new champion has entered the ring since: the Core i9-13900KS. The opportunity for our colleague to continue his work.

In order to finalize his work, Xaver Amberger recorded the SP scores of 199 copies of Core i9-13900KS. Unsurprisingly, the latest Raptor Lake processor belts the champion’s belt, with an average score of 108.1 and a median score of 108. Hardly surprising, since these chips are the creme de la creme of the Core i9-13900K; copies selected by Intel to be configured at 6 GHz.

Important precision concerning the diagram above: the V/F curve of the P-cores, which is used in the calculation of the SP of the latter, differs for the Core i9-13900KS. You have to subtract about 6 points from the results to put this processor on a par with the other two Core i9s.

No BCLK overclocking for non-K Intel Core Raptor Lake?

Also higher SP scores for E-cores

Note that the E-cores’ SP scores are also up, averaging 90.4 for the Core i9-13900KS, compared to 83.6 and 84.4 for the Core i9-13900K and Core i9-13900KF respectively. In fact, the standard frequencies of the E-cores are identical for the three chips.

The final table for Raptor Lake is available below. Note that these SP values ​​are based on an Asus algorithm: it is not an exact science, and they are only valid for this family of processors. However, do not subtract 6 points from the Core i9-13900KS results in the table below. Indeed, the values ​​are calculated from the SP scores of the P-cores but also of the E-cores, which share the same V/F curves; in short, they are already “global” SPs. To make it clearer, you find a second table with only the SP scores of the P-cores for the three Core i9s.
