A massive design flaw and security vulnerability has been found in Intel CPUs. This design flaw not only effects security, but performance as well. The affected processors require an update to the OS on both the Windows and Linux side. Once you apply this fix a performance drop of 5-30% can be observed.
One the security side of things it is pretty bad. An affected processor could have the contents of its kernel memory accessed, this is where your passwords, logins, etc are stored.
This could be seen as a big win for AMD, who processors (so far) have not been affected by this problem. The problem is at the x86 level, so AMD might not be out of the woods yet, we will let you know if anything comes of it. But if AMD’s processors remain safe a 5-30% performance drop can really change benchmarks and how AMD processors look compared to Intel counterparts.
The guys over at Phoronix have done some benchmarks on Linux pre and post-fix, you can see those results below.
