Intel Performance Hit 5x Harder Than AMD After Spectre, Meltdown Patches

The question, especially as new disclosures have stacked up, is how large the impacts would be and how would they change the performance comparison between Intel and AMD? With no fixes applied, across its entire test suite, the CPU performance ranking is:

With the full suite of mitigations enabled, the CPU performance ranking is:

AMD, in other words, now leads the aggregate performance metrics, moving from 3rd and 4th to 1st and 3rd. But the cumulative impact of these patches could result in more tests where Intel and AMD switch rankings as a result of performance impacts that only hit one vendor.
