Intel’s thirteenth Era Raptor Lake processors are a few of the greatest CPUs for gaming. There is no doubt about it. Nevertheless, have you ever ever puzzled which chips overclock the perfect? German publication Igor’s Lab (opens in new tab) has examined as much as 480 Raptor Lake processors and revealed the binning information on the silicon high quality you may count on from every processor tier.
Intel does its little bit of binning earlier than sending the Raptor Lake processors off to the retail market. Throughout manufacturing, the chipmaker evaluates every chip and implants a singular V/F curve into every one in every of them.
The V/F curve homes the info for every core relating to the minimal voltage corresponding to every frequency. The V/F curve, totally different for every SKU, tells the motherboard how a lot voltage is required for a specific frequency. Some motherboard producers, similar to Asus, make the most of these V/F curves to find out the standard of the processor and the chip’s overclocking potential.
Asus constructed a characteristic into the model’s ROG Maximus-and Strix-branded motherboards known as Silicon Prediction (SP), which makes use of a mathematical formulation to evaluate silicon high quality based mostly on the processor’s V/F curve. It leads to a easy quantity that tells you the way good the processor is.
Logically, the upper the quantity the higher because it correlates to a greater processor. Igor’s Lab’s methodology is easy. The information outlet sticks the Raptor Lake processor contained in the Maximus Z790 Hero, boots up the system, goes contained in the BIOS, and data the SP worth for every pattern.

The info exhibits that the Core i9 fashions comprise the highest quality silicon out of all of the Raptor Lake Ok-series chips. The Core i9-13900KF was the perfect overclocker, with a mean SP of 101.1 out of 164 examined samples. Even the worst Core i9-13900KF had a rating of 91 factors. The Core i9-13900K, which comes with the iGPU, was only a hairline behind the KF counterpart. The processor had a mean SP of 99.6 factors, lower than 2% behind the Core i9-13900KF. What’s attention-grabbing, although, is that the Core i9-13900K had the perfect SP rating out of the lot, with 114 factors.
The Core i7-13700K and Core i7-13700KF had been fairly shut relating to silicon high quality. The delta between the 2 common SPs was lower than 1%. Much like the case of the Core i9-13900K and Core i9-13900KF, the KF variant of the Core i7-13700K has a slight edge relating to overclocking.
On the subject of the Core i5-13600K and Core i5-13600KF, it was the exact opposite. The common Ok-series mannequin had the next common SP (81.8) when in comparison with the KF mannequin (78.5). So we’re taking a look at a 4% distinction. Surprisingly, the Core i5-13600KF additionally had the worst pattern out of all of the examined Raptor Lake elements, with a specific pattern scoring simply 58 factors.
For the typical client, silicon high quality isn’t a giant promoting level because you usually decide up a processor in response to your wants. For instance, in case you want built-in graphics, you’d purchase a $599 Core i9-13900K, or in case you don’t need the iGPU, the Core i9-13900KF sells for $574, saving you $25 which you can put into one other element on your construct. Nevertheless, for severe lovers, the Core i9-13900KF has higher possibilities of hitting the next overclock, similar to 6 GHz, like Intel’s soon-to-be-released Core i9-13900KS, which can retail for $699.
