Which one is in the ps4, left or right?

Also, what's the picture about "time to triangle"

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" is an expression from Project Managment. In every project, you are given a wad of cash, a timeline and a scope of what to do. Considers those restrictions the sides of a triangle, and your project sits within the triangle, with some room to move around (got less time? -> use more money/less features) . Basically in the graph,  it means the time from starting a "Lets make a game" project to getting a running build (not a finished product!)

That's pretty epic then! Faster development by up to 6x!!
They weren't joking when they said development costs would stay the same or go down, and that games would be incredibly easy to make.
