I imagine the new GPU will support the same Metal API. As this is probably something that Apple has been working on for a while now I'd assume that Metal was designed with this new GPU architecture in mind. How much of those tools would need to be updated to a new GPU assuming the current API was specifically written for it ?

But even if the API is the same, it doesn't mean it will have the same performance? Something that was not a problem with previous GPUs could become a bottleneck and vice-versa? And since you need to support both GPUs or else you drop older iPhone support, it might get annoying.

I don't really know if that would be the case though, I don't know anything about GPUs.

If "in certain cases, the performance profile can be annoyingly different" is the outcome of a tectonic shift in the underlying hardware, it would be a significant and praise-worthy achievement.
