Congratulations for getting this far into the thread. A reality check might be in order. Both Xbox One and PS4 are based on the same AMD APU but customised for each company. It's a 28nm fab chip of identical size. Microsoft removed some of the power of the GPU so they could fit in 32MB of eSRAM to compensate for slow external memory. Both have arm processors etc and other minor customisation beyond that. Both companies will be working hard to make their development software as optimal as possible likely using AMD Mantle as the basis of low level access of the gpu hardware. AMD won't be denying either company full information on how to fully exploit the graphic hardware. Both consoles will improve in performance over time as development software improves and developers become more familiar with them. As ever the best way to see the performance difference is to perhaps read some comparative reviews where ps4 and xbox one versions are directly compared.
Secret sauce in console terms is often a defense mechanism for a weaker console where they pretend there is some currently untapped power in a console that once utilized will allow it to outperform the console it is actually under performing against currently.
