Old Windows 7 and Windows 8 machines will be the most impacted.
In every case, your computer will take a performance hit – though it will not be noticeable for most users.
The real performance impact comes with CPU-intensive processing, such as 3D modeling, complex financials, encryption, and servers. The biggest hit, up to 30%, will be to servers running payment gateways, such as PayPal and credit card processing. And you might feel this when making online transactions.
The exact nature of this vulnerability is not public information, as the manufacturers and software publishers do not want to expose the important technical information that would provide an attack vector until all patches have been published and widely installed. Intel, AMD, ARM, and Qualcomm CPU’s are all affected.

As of this writing, Intel has already been hit with three class action lawsuits, and we expect to see more.
