Frequently Asked Questions

Which Intel® processors are affected?

For each security advisory, affected processors are identified at the Security Center under that specific advisory.

How do I apply microcode updates to my system?

Microcode updates are typically included with operating system (OS) updates from your OS vendor. End users do not have to take any special actions to apply these mitigations other than ensuring that your system OS and drivers are up to date. Contact your OS vendor for information on which OS versions incorporate the latest microcode.  Microcode requirements can be found on the Security Center for each specific advisory.

How do I update the microcode?

Intel always recommends running the latest microcode for your system by using an updated BIOS or by OS loading of microcode updates if supported by the platform. See the Security Center for each advisory with the latest details on what options are available. This is especially true when mitigating potential side-channel cache exploits.

What should I do if I’m running a Linux distribution?

Contact your operating system vendor for the latest information.

Software and workloads used in performance tests may have been optimized for performance only on Intel microprocessors.

Performance tests, such as SYSmark and MobileMark, are measured using specific computer systems, components, software, operations and functions. Any change to any of those factors may cause the results to vary. You should consult other information and performance tests to assist you in fully evaluating your contemplated purchases, including the performance of that product when combined with other products. For more complete information visit www.intel.com/benchmarks.
