AMD now has more compute on the top 500 than Nvidia

layperson with no industry knowledge, but it seems like nvidia's CUDA moat will fall in the next 2-5 years. It seems impossible to sustain those margins without competition coming in and getting a decent slice of the pie

But how will AMD or anyone else push in? CUDA is actually a whole virtualization layer on top of the hardware and isn't easily replicable, Nvidia has been at it for 17 years.

You are right, eventually something's gotta give. The path for this next leg isn't yet apparent to me.

P.s. how much is an exaflop or petaflop, and how significant is it? The numbers thrown around in this article don't mean anything to me. Is this new cluster way more powerful than the last top?

A high grade consumer gpu a (a 4090) is about 80 teraflops. So rounding up to 100, an exaflop is about 10,000 consumer grade cards worth of compute, and a petaflop is about 10.

Which doesn’t help with understanding how much more impressive these are than the last clusters, but does to me at least put the amount of compute these clusters have into focus.
