| SvennoJ said: Ahh that makes sense, so the new GPU would be a different architecture. Sounds like a massive oversight at the time the ps4 was designed, causing quite a pita for developers going forward. So brute force emulation of the base model with the option to write more efficient NEO specific code. (those separate NEO GPU binaries make sense now) Clusterfuck with a silver lining... |
at the time they finalised the PS4 they might still have been hopeful to be able to use the 20nm process in the future and there were reports of AMD attempting to make use of that one up until dec 2014, yet it seems that never came to fruition and with that died that option for X1/PS4 APUs aswell
the newest processes even have a changed transistor layout (finfet) afaik effectively making "shrinks" complete redesigns, so that might have been out of the question from the get go
