After five beta versions of macOS Sierra 10.12.2 we have an important news that has been revealed in the source code of the latter version released last Monday. In principle we usually edit to add the news found in the news of the beta itself, but in this case it is important to dedicate a new article, It's about the possible GPUs for the next Macs that will arrive during 2017. Everything seems to indicate that these three new GPUs found would be the ones that will be mounted in the following Apple computers, it is the Polaris 10 and two new GPUs Polaris 12 and Vega 10.
This discovery comes from the tonymacx86 forums where you usually find news related to hackintosh and that this time AMD's three new GPUs revealed. Something similar is what happened with the current iMac 5k with Retina display and the newly released MacBook Pro with Touch Bar, a similar leak months before gave us the clues of the equipment that we have today available from Apple.
About the GPUs we can say that the Polaris 10 and Vega 10 could be updates of what we already have in the iMac and in the Mac Pro respectively, but the Polaris 12 is a new GPU that is not at all clear where it could be used in the event that these data come to fruition. In principle, what is clear is that these types of discoveries do not usually fail, we have already seen it on previous occasions, but we cannot say which teams will mount the GPUs in a blunt way because this is something that is unknown.
