The thing is simple: you already get +75% bandwidth so you can get up to 75% more perf as long as you are bandwidth-limited and fit the memory budget.
It seems there's also an improvement in latency.
It might be a game-changer for manufacturing but it really isn't much from programming point of view. It's "just" faster memory. Except it's way faster. And as a flagship, it's fairly affordable.
