GTX 1080 Ti with it's 11GB of RAM when it physically on the PCB can have 12GB of RAM and being 352-bit when the Titan X which it's based off is 384-bit.
GTX 970 with it's odd RAM configuration of the first 3.5GB being full speed RAM and the last 0.5GB being very slow just so that it wouldn't compete with the GTX 980.
So what do you think of nVidia nerfing it's products and maybe you could give me more examples of this happening?
