FWIW I still don't understand what is not to understand here Wider memory bus => Better CPU performance + higher cost Higher cost b/c wider bus with system-in-a-package has higher cost than memory with smaller bus in standard DIMMs. Better CPU performance b/c a wider bus gets data faster to the CPU.
