A security researcher has created a tool to allow the extraction and analysis of AMD’s Platform Security Processor firmware.

There’s a clear winner when AMD and Intel go head to head in performance comparisons in Linux with all Spectre, Meltdown, Foreshadow, and other fixes applied. Intel loses a lot of performance in these comparisons.

Intel has disclosed a new set of speculative execution security issues that can leak data from CPUs under certain circumstances. How serious a problem they represent as a practical matter is still under debate.
