This processor utilizes the Raptor Lake Refresh architecture and is selected from premium silicon batches for superior overclocking potential and out-of-the-box performance. Intel has increased the maximum boost frequencies of the Performance (P) cores to 6.20 GHz and the Efficient (E) cores by 100-200 MHz, using the Thermal Velocity Boost technology. For context, the i9-14900K's P-cores have a maximum boost of 6.00 GHz. Historically, similar Special Edition processors, such as the i9-13900KS and i9-12900KS, were priced around $740, suggesting a similar price point for the i9-14900KS.
