AMD may have a couple of extra GPUs it hasn’t told us about. According to Gigamaxx from TonyMacx86 forums, three unreleased GPUs from Radeon were listed inside a controller for MacOS Sierra driver: the Polaris XT2, Polaris 12, and Vega 10. Of the three, we have only been aware of the Vega 10.
One interesting fact about this discovery is that all three GPUs are listed separately, which may indicate that they are different from one another. Both VideoCardz and Overclock3D are stating that one of these GPUs could possibly be the 687F:C1 GPU that was discovered a few days ago.
Aside from the discovery of the names of all three unreleased GPUs by Radeon, no other details were found in the MacOS Sierra driver. The Polaris XT2 GPU in particular is very interesting because it may be the chip that Radeon is going to use for its next dual-GPU graphics card – but that’s just a blind guess.
Polaris 12 on the other hand, seem to be a GPU that is going to replace Polaris 11 in the future. Either that, or it’s going to be released as new low-end segment offering from Radeon – perhaps for future MacBooks. Those aside, the more important question that everyone should be asking is: why is Radeon’s Vega 10 GPU listed in a MacOS driver? A sign of things to come it seems.
