The biggest highlight of the top-of-the-line Intel Core i9 Raptor Lake, i9-14900KS and i9-13900KS, is their boost reaching 6 GHz without the need for overclocking. Now with Intel’s requirement for the new power profile, these CPUs could be severely affected, with the possibility of the latest SKU delivering a maximum clock rate below 5 GHz.
For context, enthusiast Raptor Lake processors, more specifically the 13th and 14th generation Intel Core i9 (among other SKUs such as the i7), were experiencing performance problems due to the high energy consumption released by the motherboards.
This needed to be corrected and almost all of Intel’s partner manufacturers have already released a new BIOS that features the profile recommended by the owner of the processors, who even gave an ultimatum for all other manufacturers to also comply by May 31st.
Impacto na performance do Core i9-14900KS
These changes cause the Core i9-14900KS, for example, to lose performance in several tasks due to a lower boost. The video below shows how the CPU in question behaves with the “performance” power profile, which still delivers better results than the “Intel Baseline”.
With this configuration, the CPU delivered around 5 thousand points less in Cinebench R23 compared to the SKU in the extreme power profile in the multi-thread test.
Performance loss also happens in games. In Shadow of the Tomb Raider, in the game’s own benchmark, there was a loss of 25 FPS in average performance. Something similar also happens in F1 23, Horizon Zero Dawn and Cyperpunk 2077, games that also recorded a loss of more than 20 FPS on average, depending on the scene.
Considering that the performance profile used in this video delivers 307A of current, and Intel’s new power profile reaches 249A, the performance drop will be even greater, with these Core i9 Raptor Lake CPUs delivering even less performance at lower frequencies.
It is worth noting that the Intel Core i9-14900KS operates with maximum boost on performance cores at 5.2/5.4 GHz, with 5.1 GHz as a minimum, with the performance profile. This, consequently, causes the processor to operate at lower temperatures due to lower energy demand, the only benefit of this situation.
