Is this true? That's pretty damning.
- Laaas 9y agoIt's not really a lie, but technically the Ryzen architecture doesn't have 256-bit instructions internally. Not like it matter much to you though, because these are all implementation details, and don't really make a difference for you, other than changing how you should optimise your code for max speed.
