Intel Fixes Critical Performance Bug in 13th and 14th Gen Processors: Warranty Extension and Microcode Update 0x12B Announced

The official press release

Intel Core 13th and 14th generation processor models based on the 8P + 16E “Raptor Lake” silicon are prone to an infamous bug that caused their performance and stability to deteriorate over time due to overvoltage response by extending the warranty on affected processor models and releasing a series of CPU microcode updates packaged in UEFI firmware updates for motherboards, through PC OEMs and motherboard vendors , with the last microcode update as 0x12B There is good news: Intel has extensively tested the affected processor models and confirmed that the 0x12B microcode solves this problem.

The Verge recently interviewed Intel spokesman Thomas Hannaford on this topic, who said that the company had identified four situations that caused processors to slow down irreversibly and that the company had proposed changes for stable processors before the contamination occurred. If the processor is unstable (ie has started to degrade), the firmware update is of no use and you should simply replace the processor under warranty. Intel has extended the warranty to even the first purchase of affected processor models. “Yes, we confirm this is the cause and it has been resolved”Intel spokesman Thomas Hannaford tells The Verge.
