What astonishes me about this whole debate is that Xbox fans like to downplay actual facts, like confirmed specs, and instead jump on any PR slogan and/or rumors from ANY source, just to latch onto a shred of hope that their console won't underperform against the competition. The cloud (which this guy bringing up, again), barely upclocked CPUs/GPUs, dGPU, their SW engineers are better than Sony, and God knows what next.
It's time to face it guys, the PS4 is more powerful than the One. The systems are built near identical, so it's very easy to compare them this time. Only real difference is that one has much faster RAM and a better GPU, one that pumps out an extra ~500 Gflops (more than 2x what the Wii U is estimated to be capable of). That's no small difference and is larger than the gap between PS3/360. A difference that will become even clearer as developers get a handle on both machines.
Having said that, why should you even care? You have no interest in getting a PS4 and are getting the One for its exclusives, which is totally fine, so just accept it an move on. Instead, we get a bunch of people (I guess) trying to justify their purchase and just spreading FUD about how the differences will barely be noticeable. Don't get me wrong, this will probably be true for multiplats, but it's a totally different story for exclusives.
