During AMD's presentation at Computex 2016, the company showed no fear as it compared the new Polaris-basedRadeon RX 480 GPUtoNvidia's GeForce GTX 1080. The $700 Pascal-based powerhouse was tested inAshes of the Singularityversus a pair of the Polaris GPUs and came away a little embarrassed in this scenario. AMD presented a slide that claimed the GTX 1080 only managed 58.7 (we presume average) FPS, while the Radeons pushed out 62.5 FPS using the same settings.
>Robert Hallock, AMD's Global Head of Technical Marketing, madea postinthe official AMD sub-Redditsays this in his post:
>Ashes uses procedural generation based on a randomized seed at launch. The benchmark does look slightly different every time it is run. But that, many have noted, does not fully explain the quality difference people noticed.
>At present the GTX 1080 is incorrectly executing the terrain shaders responsible for populating the environment with the appropriate amount of snow.The GTX 1080 is doing less work to render AOTS than it otherwise would if the shader were being run properly. Snow is somewhat flat and boring in color compared to shiny rocks, which gives the illusion that less is being rendered, but this is an incorrect interpretation of how the terrain shaders are functioning in this title.
>The content being rendered by the RX 480--the one with greater snow coverage in the side-by-side (the leftinthese images)--is the correct execution of the terrain shaders.
>So,even with fudgy image quality on the GTX 1080 that could improve their performance a few percent, dual RX 480 still came out ahead.
