Hello iroxter

 

 

Thank you for contacting Intel Technical Support,

 

 

We received your inquiry and I understand that you are looking for information on the performance degradation. Please accept our apologies for any inconvenience this may be causing. We will be more than happy looking for a solution.

 

 

About the performance, I will like to share with you that on some workloads or benchmarks may be impacted and will vary depending on the microprocessor and platform configuration (hardware and software). While some specialized workloads may see a noticeable performance impact, for most users any impact will be modest.
