| petalpusher said: 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. |
The problem is your assumption that this is about the Xbox One being better than the PS4. It isn't.
It's about the performance features of the Xbox One mitigating the specification advantages of the PS4. Does it make the Xbox One 1:1 to the PS4's specifications? Nope. But it does narrow the performance gap.
12 CUs will never be more than 18 CUs, but 12 CUs operating faster than 18 CUs will narrow the performance advantage of those 18 CUs. That was Pennello's point.
