New AMD Radeon GPUs Polaris 10 XT2 and Polaris 12 Appear on Mac Drivers


An eagle-eyed Mac Mac in the forums tonymacx86 has discovered some interesting new log entries in the 9500controller software.

It's a busy time for AMD, especially on the graphics side of things. Today we look forward to seeing the launch of its new Radeon Crimson ReLive software, with a dedicated game capture tool built into the drivers, as well as a host of other performance improvements and new features. And things seem to be even busier as the discovery clues based on OSX.

Inside the 9500controller driver software, a forum user has discovered registry entries for a couple of new AMD GPUs. The Polaris 10, 11 and Vega 10 GPUs we already knew, but the Polaris 10 XT2 and Polaris 12 chips are new to us. Now either Mob Jobs are getting their own custom Radeon chips or AMD is ready to go big on their next generation of graphics cards in the new year through the board.



For me, this sounds like a new RX 500 series of AMD Radeon graphics cards appearing relatively soon. We already knew that the architecture of the Vega 10 GPU is scheduled to arrive in the first half of 2017, but this information paints an image of a range of cards covering both Polaris and Vega architectures. Something we have long suspected ...

The Polaris 10 XT2 naming scheme follows AMD's tradition of upgrading older GPUs for newer GPUs, last seen with the Radeon HD 7970 GHz Edition and the R9 280X with the Tahiti XT2 upgrade to the Tahiti XT chip. It is not unreasonable, then, to expect the RX 580 to come with a Polaris 10 XT2 GPU with the RX 590 swinging the Vega 10 silicon. Where does the Polaris 12 come from? Well, that could be a direct replacement for the low-end Polaris 11 GPU on the next generation of Radeon cards.

It is increasingly likely that the long-awaited AMD RX 490 will never happen and will move directly to the RX 500 series of cards.
