Different settings/ - possible, bot not sure, because in theory, the same graphic settings should be used. Although you know better, since you are the author of both reviews
test scene/ - The most logical option, but again, usually using a standard performance test or the same scene. Although...
drivers/ - Possibly, but not that significant. Although, of course, there were cases when a more recent driver gave a decrease in performance.
test system/ - About the same, last time the test system had 13900k, now the absolute gaming flagship is 9800x3d. But do not forget that testing was done at maximum graphics settings in 4K, where the processor does not play a big role. (Memory& storage are great too).
Please forgive me for my stupid tediousness. But this is just my curiosity.
Anyway, great review, as always. A herculean job.
