i dont consider X1 as next-gen console, mostly because it still operates around the same old 128-bit memory interface of DDR3.

lol GDDR5 and DDR3 from the same family, the XB1 actually has higher bandwidth to the CPU than the PS4. ESRAM pi*** on the GDDR5 where it matters. And before you talk about the 18 CUs, the 4 cu's are worth sh** Sony already admited it. That leaves just 2 CU more than XB1. Guess what? the higher clocked GPU will pi** on the extra 2 CU. Sony pulled a fast one and cows fell for it just as last gen.
you have no idea what you are talking about, stop implying the Jaguar CPU in both consoles can even use anything close to 60 gb/s in a cycle...when did Sony say 4 extra CU's are garbage ? :lol:
Microsoft has stated and DF has stated that their is diminishing returns on adding CU's around 12-14 CU's, adding more CU's doesnt scale linearly anymore, okay, so Sony is RECOMMENDING, not FORCING, that developers use the 14:4 model, doesnt mean they have to use that CU setup at all.
so no, the 4 extra CU's arent useless, because those 4 CU's will be applied to GCN compute, over 400+ gigaflops for awesome physics and everything else while the Xbox One will still be stuck using 12 CU's, 2 LESS then PS4's 14 CU's for graphical rendering and stuck with absolutely no compute from the GCN GPU LOL
so wow PS4 having 2 more CU's for graphical rendering and over 400+ gigaflops dedicated to physics,raytracing audio, compute, everything.
sorry to say but either the Xbox One tries to match the PS4 in compute by dedicating CU's to compute, 8:4 if trying to replicate the 14:4 model of the PS4 or its games will suffer HARD when compared to ps4 games and have sucky physics and everything else.
oh and BTW, Xbox One CU count isnt in the diminishing returns terroritory of adding CU's to a GCN card, so if it were to even try to match 14:4, you will see even more of a drop per CU because from 1-12 CU's it does scale linearly, meaning a bigger dip in graphical quality, etc
On certain segment, CUs can scale...
I'll post another 768 stream processor GCN, but with lower memory specs i.e. AMD FirePro W5000 SKU.
FirePro W5000's 102 GB/s video memory bandwidth and has four links to L2 cache pools.
Some gaming benchmarks for AMD FirePro W5000.

7850 = 45.
W5000 = 33.
FirePro W5000's 12 CUs (825 Mhz) scales down from Radeon HD 7850's 16 CUs (860 Mhz).
7850's 45.3 fps / 16 CUs (860Mhz) = 2.831 x 8 CUs = 22.65 fps which roughly matches 7750's 21.5 fps result. 7750 is clocked at 800Mhz.
My scale down theory vs actual results works.
If we use the 7850 and 7750 as the two points for the "line of best fit", FirePro W5000 falls into the expected slot for scaled 12 CUs @ ~800 Mhz i.e. 2.831 x 12 CU = 33.97 fps.
