In a recent statement, Intel has assured users that the upcoming microcode patches addressing the voltage issue in 13th- and 14th-gen Core processors are expected to have minimal performance impact. The company’s internal tests indicate that while there may be minor fluctuations in performance, these are within normal run-to-run variation and not significant enough to be noticeable in everyday use.
Intel’s statement clarifies that unlike previous instances, such as the “Downfall” bug affecting older Core chips—which saw performance reductions of up to 40 percent—the current patches will maintain performance levels close to their original state. Specific tests like 3DMark Timespy, WebXPRT 4, and others showed only minor variations, with a few sub-tests showing moderate impacts. However, the general gaming performance remains largely unaffected, with only a slight exception in some titles.
Additionally, Intel has confirmed that the new microcode will not restrict overclocking capabilities for 13th and 14th Gen Core processors, although users should be aware that overclocking may void system warranties. The company has also extended its warranty program on affected processors to five years.
Intel detailed the voltage bug, describing it as a result of faulty microcode causing incorrect voltage requests, which has led to issues like BSODs in some systems. The latest microcode update aims to limit voltage requests above 1.55V to prevent instability while improving operating conditions for affected processors.
The patch will not be distributed via Windows Update. Instead, users will need to obtain it from their motherboard or PC manufacturer’s support sites. Intel continues to work on further mitigation strategies and will provide additional updates by the end of August.
