They are MATMUL machines by design already. They do not need to "accelerate" AI to begin with.
Their cores/shaders can be programmed to do that.
Also, name a current gen GPU which doesn't have video encoding/decoding capabilities/facilities in silicon, even ones which do not allow shaders to be used in this process for post-processing. It's impossible (to not to have these capabilities) at this point in time.
I said that the core (3D rendering hardware) of a GPU with shaders is the AI block already, and said that other tasks like video encoders have their own blocks, but still pull capabilities from the "core" to improve things.
