What do you think about the Power PC architecture? It has the ability to have many many threads per core? Would PPC work with gaming or?? would it be a wasted effort? Just curious your thoughts on the subject!! I bring it up due to Nvidia working heavily with IBM......NVLInk has my curiosity peaked for sure. I hope it comes to X86-64 but that looks doubtful. I would like to see a new Architecture besides X86, and Arm jump in to stimulate the market/competition!!!
The previous generation of consoles was Power architecture. Xbox 360 used a 3-core Power very effectively. PS3 had only a single Power core and 7 Cell processors (6 usable), some developers managed to make some use of them.
It's still used to good effect in supercomputing. But for game development, which is far away from what IBM and Cray are doing, supporting multiple CPU architectures that customers don't actually have is burdensome, requiring skills that are scarce in the game developer community and leading to products that nobody has hardware to run.
Computer hardware is not about having the best or most efficient architecture. It is about having a platform that will run software people actually want, right now, and will buy in order to run that software.
