50% less cores and 33% less peak shader throughput. Due to this, it needs less video bandwidth than PS4.

WHAT??????????????????????????????????????????

If you want 1080p 60Hz games (and this is the target for both consoles), you need a frame buffer that can handle the data transfer. This defines the minimum video bandwidth you need. Everything above the minimum helps you for better textures etc.

And fyi, 8G gddr5 1.25V needs LESS power than 8G ddr3 + 32M esram. And fyi2, gddr5 ram is actually easier to put on a mainboard than ddr3 ram.

So spelled out for you: gddr5: less heat, easier cooling (you will be surprised once you see how "simple" the cooling in the PS4 looks), less board complexity, faster memory throughput overall = more options.

Really, the main reasons for DDR3 are:

1) Lower BOM cost (yes I know it is more expensive than PS4 but that is NOT due to RAM cost)

2) Latency for media function, where the Xbox might show a slight advantage..
