the article almost seemed machine-generated to me; did it actually
say anything that we didn't already know (basically, that avx-512
in skylake/purley can perform double the vector rate of avx(-256)?

yes, strange indeed.  in fact, if the article is about vectorization,
one could easily argue that the GPU model for vectorization (since surely
a SM has to be considered a vector core) is in some ways working out
better than the accretion of SIMD hacks in x86_64...
