Yes, and? I never said they where. TF for TF, RDNA2 is doing much more. But so does GCN over G70, obviously. Backwards compatible, yes, not something that did exist on PS3 to PS4 exactly. The comparison is kinda flawed there i think.
Now you take on BF4 again, have you actually played the game on both PS3 and 4? Its a world of a difference, try multiplayer. On PS3, the settings equal to lower then low (yes, i have tested that backthen), the FPS is capped to 30 opposed to 60 on PS4. Further then that, map sizes and player slots are limited to 24 players on smaller maps. Thats a fckn huge difference to me. Aside from the rather laggy and stuttery experience the PS3 version was.
Its not just 'but with better settings' either, settings matter alot, going from low all the way to Ultra (what BF4 pS4 is running, about), is a huge difference to performance. Going from low to Ultra, while doubling the frame rate, and upping the resolution considerably.... and then also enabling 64 player matches as opposed to 24 on the PS3, all the while opening up the maps to the larger sizes. Sounds like a generation difference to me. Forget about the PS3s performance when things get hasty.
See what it does to the PS3.
Well, wherever forum that was you got banned for attacking members. Anyway, on to the technical discussion.
Again, i am not claiming that paper specs mean everything, they clearly do not. Im aligning those with what we see. Where did i state that RDNA flops equal GCN flops? Quote me on it.
Il try to explain again, we both are no english native speakers so it could be that. What i mean is, going from G70 to GCN, there was a huge architectural improvement, which means a better IPC for GCN. Its the same for GCN to RDNA2. Some argue though that the architectural improvements seen going from G70 to GCN1.1 where bigger then going from GCN to RDNA. But i cant prove it. Another member agreed on me on that one though.
Okay, i was just looking at the overall fidelity of those titles. But lets say going from UC4 thiefs end to last of us 2, both are using baked lighting right. Both are ND (one of the better studios), one is early title, one is a last. Last of us 2 is doing things better obviously, but saying they are heaps and perhaps a generation apart isnt what most are going to agree with.
To this day, i still think UC4 looks amazing, in some scenes/environments.... the water, effects, lighting. While last of us did improve on the engine, their close enough to me. Its more in the details between those two. You'd also have to compare PS4 versions for this, the Pro obviously lifts the resolution and stabilizes the frame rates for the latter.
DS and rift apart are fully designed around and for the PS5 only. Its what i was comparing to. Theres a reason i from the start left out cross gen titles since they wont tax any new system to their capabilities. But since you went on BF4, well, there was my view on it.
Edit: as a fair sidenote, BF4 PS3 in todays standards would have been de-listed day one. Its performance is such a hot mess, and considering BF is a MP oriented title to start with (where systems get stressed, not SP), 24 player matches, 32 sized maps, lower then low settings accompanied by the framerate as it was, that had nothing to do with Battlefield anymore.
