It definitely is an accumulation of what Roy Read has done, don't think Hector did anything to cut down R&D on the graphics side.
Gotcha. Do you happen to have any links handy? All I remember is that Rory wasn't particularly liked by the graphics guys, and that he favored the CPU division while cutting back heavily and disparaging the GPU teams. Makes me wonder what AMD was thinking in hiring him, with his IBM background (tbh when I saw that on his bio, the first thing that came to mind was "monolitic robot exec", lol).
Edit: all I could find with a quick search was this: So what did Rory Read do wrong?
