I had bet that matmult would be in transformer-optimized hardware costing a fraction of GPUs first class in torch 2 years ago with no reason to use GPUs any more. Wrong.

I think they’re referring to hardware like TPUs and other ASICs. Which also exist, of course :)

Sure but GPUs literally have MMA engines now
