What they mean is that function of the pipeline is faster, texturing will be done in another pass.
Note this passage
"The Xbox One does have some advantages over the PS4 however, with one dev explaining, "Let’s say you are using procedural generation or raytracing via parametric surfaces – that is, using a lot of memory writes and not much texturing or ALU – Xbox One will be likely be faster." "
Not so many games won't have TEXTURING.... so, that was a best example backhanded compliment, but, it means while they are loading things slower from RAM they can hopefully get some things done fast offscreen using some geometry only based operations, though, it means you have to keep shuffling things through that ESRAM, not that you necessarily want to, at least it's there.
