Actualy, it doesn't.  Because it came to light at GDC that the PS4's memory architecture isn't as great as it sounds.

While the GPU gets the top speed, of 120 or 170 GBps, the CPU only gets 20GBps.  So CPU wise the two consoles are just about even steven, and GPU wise the next Xbox is only slightly slower.

The margin of difference in performance now is less than 1%.

The opposite happened in the GDC... the PS4 architecture seems even more impressive and strong.

Except that it didn't.

I'm not suggesting that the PS4 isn't an impressive machine, I'm saying the hyperbole over the GDDR5 memory was a bit premature.  The entire PS4 doesn't get the advantage of 176GBps throughput.  It's 20GBps on the CPU.  The same, in fact, as on the next Xbox.  The difference thus is that the next Xbox has 170GBps throughput as opposed to the PS4's 176GBps to the GPU.

And my apologies.  I was overzealous in my estimate.  The performance difference is a 3% gain for the PS4.  I doubt you'ld notice the difference between 7 and 10 ms.
