Re:Ask HN: Why we can't our CPU be as powerful as our GPUs by felipebrnd on Tuesday April 23, 2013 @07:41PM (#5598687)
GPUs are great crunching numbers and CPUs are better with complex logic stuff...

And GPUs have a lot of simplified cores they simply can't handle every operation a CPU core can. Maybe you can get a hybrid hardware... replacing the space used for CPU cores by GPU cores and some kind of fast access memory...

Wasn't that one of the things that the Cell processor was trying to do? Originally there wasn't supposed to be a GPU for the PS3.
