It's actually better this way if they want more power. these are not the same APU's you'll find in PC. They have dedicated high speed RAM and a large die that can hold a full GPU. these are much more complex and powerful than any APU on the market.. while it's true that they could have gone the CPU+GPU route, it would have made the system only marginally faster, but with a much large production cost and ofcourse extra power and heat from the chips themselves.I am still surprised that both consoles chose to go with an APU and not any form of dedicated graphics.
One problem is that MS decided to add besides the GPU and CPU extra ESRAM. this means they had less space on the die, thus they were forced to cut a big chunk of the GPU. even so they were only able to squeeze in only 32 MB.
