Pascal with DDR5 ram? Small Pascal? Nvidia still has room to grow with DDR5 considering the 980 is only 256bit, moving to 384bit will give them a 50% increase in memory bandwidth. 512bit double the bandwidth. Big Pascal can use HBM2 but little pascal I don't think needs it yet.
They are not going to waste time making a pascal on 28nm and waste resources and drive them away from upcoming big product. That is silly!!
