The main point of uniform buffers is that you don’t have to set uniforms per draw call, but only per frame. And if you have alot of them and you are CPU bound, then performance gain will be noticable in CPU part.

Our internal benches surprisingly did not show a real difference. Hopefully this is due to the youngness of the driver… because this concept was lacking since a while but if there is no performance gain, it unfortunately becomes useless. I will be happy to see a bench showing me that I am wrong.

Probably a dirty cpy/pst from the Intel data. Article updated!

R9 280x is the same as 7970
