Intel’s fix for the Raptor Lake issues may reduce performance by 6.5%, but there’s more to it than that

It’s no secret that Intel has been experiencing major problems with its 13th and 14th generation desktop processors for almost a year now, which has slowly eroded some of its best processors – especially the Core i9-13900K and Core i9-14900K – in terms of performance. And now there’s a new instability update that seems to slow speeds even further.

Users have been testing Intel’s latest BIOS patch, which should fix the instability on Intel’s 13th and 14th generation processors. However, user twfox on the Chiphel forums has noted a 6.5% drop in the Core i9-13900K in Cinebench R15’s single-core performance. In the Cinebench R23, the Core i9-14900K dropped about 2% in its multi-core performance score, putting it behind the AMD Ryzen 9 7950X.
