I remember seeing an article where Ubisoft claimed the PS3 processor is actually more capable than the PS4 processor. So why didn't Sony just use it for PS4? That could have made PS3 BC on PS4 relatively easy as well! Well I'm guessing because Sony agreed the Cell was a pain in the ass and not worth using again. |
PS2 had weird instruction issue on both (CPU/GPU) side. This made porting the game to another console very difficult, and was done intentionally. Developer really don't have a choice on which console and/or hardware they have to work for. Those who funds the project makes the decision.
For Cell, Sony probably didn't wanted to spend money for developing newer version of architecture. They have to update Cell with current processing technology (~20nm) and they have to redesign front-end to utilize GDDR5. (Otherwise, they are stuck with Rambus Ram, or DDR2.)
Also, appeasing to developers includes supporting Out of Order execution.
