AMD RX Vega GPU to support more DirectX 12 features than Polaris

Up to DirectX 12 level 1

Like you might know, there are different DirectX 12 features levels and they’re categorized in tiers. A few days ago, NVIDIA has added DirectX 12 support to its Fermi series of graphics cards and meanwhile there are more rumors about the upcoming AMD RX Vega GPU in that regard.


According to a table on Wikipedia, Polaris based graphics cards support DirectX 12 level 12.0. Compared to that NVIDIA supports DirectX 12 level 12.1 in the case of their Maxwell and Pascal based GPUs. According to latest rumors, AMD is going to support DirectX 12 level 12.1 with their upcoming RX Vega graphics cards. In a head-to-head between Vega and Polaris, Vega supports Conservative Rasterization Level 3 which Polaris didn’t support at all. NVIDIA’s Pascal based “only” support Conservative Rasterisation Level 2.

Furthermore AMD has also enabled support for Raster-Ordered Views and Tiled Resources Level 3, two features that NVIDIA also supports with Pascal and Maxwell based GPUs. In addition, AMD has implemented support for lower minimum precision levels with DirectX 12, therefore 16-bit precision floating point calculation can be executed. In the case of PC gaming this is a new feature. So far only the PS4 Pro shipped with support for 16-bit precision floating point support.
