The thirteenth generation of Intel’s Raptor Lake processors is unprecedentedly among the best processors on the market, and in particular for gaming in general. The German company Igor’s LAB took care of their overclocking potential in cooperation with MIFCOM. They tested over 480 Raptor Lake series processors and then published their results in the form of a bining report on their overall performance.
Igor’s LAB, in cooperation with MIFCOM System-Integrator, tested 480 Raptor Lake series processors in terms of OC potential, and the Intel Core i9-13900KF achieved the best result.
ASUS ROG Maximus Z790 Extreme motherboard review – It’s great, but twice as expensive as the Intel Core i9-13900K
Intel during the production process performs its own bining data before sending the processors for sale. They evaluate every processor they make and implant it with data on their estimated V/F curve. It stores the relationship of the minimum voltage to each frequency for a given core. Each motherboard, based on this curve, knows what voltage must be supplied for a given core frequency, and some companies, such as ASUS, use a specialized mathematical formula Silicon Prediction (SP) to determine the quality of the processor. The higher the value, the logically the processor is better. Igor’s LAB used this method in its study. Together with MIFCOM, they used the ASUS ROG Maximus Z790 Extreme motherboard to generate accurate data for each of the Raptor Lake processors.
Corsair Dominator Platinum RGB 7200MHz CL34 DDR5 RAM test – What performance with Intel Core i5-13600K?
The above figures show that Core i9 processors have the highest potential in terms of overclocking as well as the overall quality of the silicon wafer. The winner of the test was the Intel Core i9-13900KF processor with the highest average SP score of 101.1 points – where exactly 164 processors were tested. At the same time, even the worst used Core i9-13900KF processor had a score of 91 points. The Intel Core i9-13900K processor, whose main difference is that it has an iGPU, achieved an average score of 99.6 points, which is about 2% lower than the Core i9-13900KF. Interestingly, however, the single highest score was achieved by the Core i9-13900K with SP of 114 points, but it does not provide stability on a larger scale.
NVIDIA GeForce RTX 4090 – Performance Test on AMD Ryzen 7 5800X3D vs Intel Core i9-13900K in Graphics Spaces
The results of the Core i7-13700K and Core i7-13700KF processors were very close to each other. The former obtained an average SP score of 82.9, and the latter 83.5, where the difference between them does not exceed 1%. Similar to the Core i9-13900KF processor, the non-iGPU version fared better in the overall tests. It is also worth noting that the iGPU version also achieved a one-off SP score of 96, while the Core i7-13700KF peaked at a maximum SP of 90. This may indicate a slightly lower quality of units with integrated graphics compared to much more stable versions of the processor. without iGPU.
Intel XeSS vs. NVIDIA DLSS – We Test Image Upscaling Techniques in Shadow of the Tomb Raider and HITMAN 3
The situation is different for the Core i5-13600K and Core i5-13600KF. In this case, the model with integrated graphics achieved an average SP score of 81.8 points, and the model without iGPU 78.5 points. As in previous processors – the model that lost in the overall test average also achieved the single highest SP score of 96 points. It is also worth noting that despite having a sample that scored high, the Core i5-13600KF model also scored the lowest score of all processors at 58 points, which is rather poor news for customers. This means that the production level model without iGPU has some minor problems with its wafers, so in this case it is worth choosing a model with iGPU.
Which processor to buy? What to choose in the price range from PLN 400 to PLN 4000? Better Intel or AMD? Processor Buying Guide
It is worth noting that the report from Igor’s LAB is much more extensive than just a general comparison of processors. In it, they show a thorough comparison between Performance and Efficient cores and test them independently of each other. On page Igor’s LAB see their full report. The final conclusion of the bining data is that Intel has significantly held back on the performance of the Core i9-13900K processors, so as to be better able to promote their latest Core i9-13900KS processor, which offers a core clock of 6 GHz right out of the box. After all, based on the data, the best processor for OC is the Core i9-13900KF model.
