On the left is the PS4 as it turned out, on the right is an alternate PS4 as it could have been designed. Notice on the right, the gpu memory throughput would have been much. much higher had they taken that road. Unfortunately, the downside would have been only 8 chips on a 128bit bus (in clamshell mode, so a max of 4G ram), and the programmer's mess of actually using a small cache to its maximum (the mess XBox One programmers have to overcome). |
Time to triangle refers to the polygon. More specifically how much time it takes until your graphics engine can render the amount of polygons appropriate to capabilities of a given hardware.
