Thats a perfectly normal thing. Xbox one has also 128 hidden Stream processors. Its simply for yield purposes. So they can use the wafer with less active CUs too. There will never be a firmware update enabling the additional CUs. Because millions and millions PS4s will have just 19 or 18 CUs active and not 20. Sony can not activate the CUs its pointless to speculate about, same as the additional SPE can never be activated because alot of PS3s do not have a working additional SPE.

Xbox one has also 14 CUs and not 12 yet they will never activate the other CUs. Ps4s are not Graphic cards where with alot of luck you could activate the working CUs with a firmware update if your chip has them. Because every PS4 has to have the same power in order for the games to run identical.

 

Edit: Seems my post was pointless as other posters mentioned it before me should have read the second site of this thread too before posting...   

But you explained it best, and why they will not be turninh it on.

They will opmtimize now by software, not turning on extra hardware and increasing failure rate because not all of the extra CU's will work.
