After skimming the article, I'm confused -- where exactly is the headline being pulled from?

If you look at the table toward the bottom, no matter how you slice it, Nvidia has 50% of the total cores, 50% of the total flops, and 90% of the total systems among the Top 500, while AMD has 26% of the total cores, 27.5% of the total flops, and 7% of the total systems.

Is it a matter of newly-added compute?

> This time around, on the November 2024 Top500 rankings, AMD is the big winner in terms of adding capacity to the HPC base.

Said table is titled for "Accelerated Supers" (i.e. only ones with GPUs) so the numbers can't be applied to the Top500 as a whole like that. Combining numbers from the summaries at the bottom of the table titled for "All Supers", Nvidia is more like 38% of Top500 FLOPS as they don't have any non-accelerated systems in the list.

Knowing all of that it still leaves unexplained whether AMD has the needed ~70% of non-accelerated compute (assuming FLOPS) to clear the bar for the headline. It seems unlikely to me... but the article doesn't actually have enough data to be sure one way or the other.

That's a good point.

That said, I assumed the context of the article was specifically on the topic of AMD GPUs, and not, say, Epyc processors, so if so, it's ultimately irrelevant.

(Also, there are just over 3 exaflops across non-accelerated supers; AMD would need > 2/3 of the remaining share in order to surpass Nvidia on that front as well.)
