We have already talked on several occasions about the stability and degradation problem suffered by the 13th and 14th generation Intel Core processors, also known as Raptor Lake and Raptor Lake Refresh. After several microcodes that supposedly fixed the problem, Intel finally released microcode version 0x12B with which, now, they promised to solve the problem that they themselves called Vmin Shift.
Motherboard manufacturers such as MSI, Gigabyte or ASUS have already published BIOS versions with this update, but it seems that the first performance tests show that, contrary to what Intel promised, there is a notable decrease in the performance of the motherboards. processors.
This has been shown by the first users who were able to test these BIOSes with a Core i9-13900K. Specifically, in the Chiphell forums you can see that the Cinebench R15 score drops by around 7%. The user attributes this to the voltage and status restrictions applied by the new patch.
We will have to wait to carry out more tests and check if this decrease is generalized or something specific. It seems that what is most affected is single-core performance, so it would only be relevant for core- or IPC-dependent applications, such as games.
