Penello specifies why X1vsPS4 performance difference is overstated

There is so much more that 7950 has better.  So it should have a higher performance.  But even with all those advantages, it just over doubles performance, even with nearly three times the CU Cores.  It should be much higher. 

oh it works with the HD 7850 vs HD 7770 too (the HD 7770 still have way higher clock). I just took the extreme example that produces a 100% increase in performance with CU running at way lower clock. In fact it works with every gpu in GCN architecture, if you scale up the CU count, it performs better not on paper but in real world performance, and on the contrary, i would add, it just continue to scale up really well if you have more BW and ROPs in conjonction, just like the PS4 have. Between 7770/7790 and 7850/7870 there s a significant gap, it's a  50% real world performance difference, sometimes even more.

So try to spin the CU advantage over frequency or inefficiency, is just ridiculous.

And lets keep in mind the PS4's GPU have 18 CU, not 16 like the HD 7850, also more TMUs (+4), and more bandwidth than a HD 7870 (145 vs 176 GB/s),  ACEs customizations,..

Just a few days ago, we were debating the funny assumption that the X1 would get a 4.8 Tflops stacked "dgpu" (that was good laugh), now we re back to hd 7770/7790 level that would magically perform better than gpus with 50% more CUs and 100% more ROPs.

Xbox extremists always deliver in hardware discussions.

I completely agree with the highlighted part, but have you read what you are saying?  You say it doesn't work and doesn't matter, but then it magically matters on the PS4.

The 7790 has nearly three times the CU's of the 7950, yet is barely twice as powerful.  So CU's don't make the significant change would would expect on the 7950.  Why does it matter on the GPU cards but not on consoles?  Isn't that what you are saying or do you mean something different.  Not trying to be hostile, just seems contradictory.
