512b DDR would only bump top speed to around 140gb/s which is still slower, at the cost of pay transistor space, higher memory cost and more heat produced, the most likely would have had to drop the esram to fit the controller in and the end result is its still slower

512bit DDR3 would bump it up to 136Gb/s.
If Microsoft opted for DDR3 Ram that was running at 2750mhz on a 512bit bus it would be equal to the Playstation 4.
If Microsoft opted for DDR3 Ram that was running at 3000mhz on a 512bit bus, it would be faster than the Playstation 4.

Heat and Memory cost isn't a drama, I've played around with Sammy's DDR3 green sticks overclocked to 3ghz and they run perfectly happy at low volts and without any heatsinks, the bonus? They're dirt bloody cheap.

Obviously there are reasons for not going that route, but the heat and memory cost itself isn't one of them.
