What Macs support Metal 2 in High Sierra ?
I think they are the same that support first version of Metal, and here is the list for Metal supported Macs.
There are three tiers of GPUs that support Metal. Metal 2 is a continuation of Metal and simply adds features to the existing set of APIs. Some features require a certain family of GPUs. This gets much easier on the Mac however, where, if I remember correctly, there's only a single family. All Macs 2012 and up support this family for sure, and select others may also. This includes all functionality of Metal 2.
At first I thought so too but Metal 2 is heavy and has a lot of new stuff that old GPUs like the GT650m / GT750m (which support Metal 1) can't keep up with.
According to the WWDC sessions however, All features of Metal 2 seem to be supported on all Metal capable devices. I've not yet seen all the presentations, but so far there's none that talk of adding a new family to the Mac GPUs and no documentation to support that either.
What features of Metal 2 do you not think something like the GT 650M should be capable of performing? I will gladly look into the matter more for that particular GPU. I should be able to borrow a laptop with that GPU and run High Sierra on it, and perform some very quick tests (if I can easily understand and implement the APIs of the features you're thinking about )
Thanks so much for your offer.
I have in the house two 15-inchers from 2013 with those GPUs so I can do my own testing if needed.
The key word here is 'if needed', the question was more of a curiosity for me because I don't need to implement any APIs.
Thank you again !
Sure . You're welcome. If you do end up making any discoveries one way or the other, let me know.
