It’s no secret that Intel has been experiencing major issues with its 13th and 14th-gen desktop processors for nearly a year now, which has been slowly tanking 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 be dropping speeds even more.
Users have been testing out Intel’s latest BIOS patch, which is supposed to fix instability on Intel’s 13th-gen and 14th-gen processors. However, user twfox on the Chiphell forums has noticed 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% of its multi-core performance score, putting it behind the AMD Ryzen 9 7950X.
