With all the talk of how 'balanced' the ps4 hardware was when it was released this is a weird change. More than double the gpu without doubling the (already weakest link) cpu.
If DF is right and they use polaris then at least the memory bandwidth will not be an issue, as it (and fiji before it, and maxwell for nvidia) has new color compression support that greatly reduces the bandwidth needed.
If it still uses gcn 1.1 then then that would make two weird choices, as they'd be memory bandwidth starved
so it's like having an already lopsided PC with a gash processor and mediocre graphics card and spending $400 for a mild overclock and a new decent graphics card, factoring a new case, psu, disc drives and motherboard into the cost because that's how you roll.
Yeah I don't get it either.
The gpu in ps4 is fine ,really, for 1080p 60 fps with somewhat reasonable settings.
Instead of a much needed cpu upgrade they just put in a disproportionally more powerful gpu that is doomed to be bottlenecked, so developers will still be forced to choose 30fps with shinier graphics as 60 fps will be off the table due to the cpu (open world games for example)
Even if you don't care about framerates, graphically a lot of ps4 games suffer from very poor draw and shadow distances and those are not the gpu's fault. And a better gpu is not going to fix that. A better cpu would have fixed that and improved graphics hugely by making them more consistent rather than pretty up close and garbage at a distance (no more annoying distracting pop in or potato cereal box builtings at a distance)
If I had to choose between an i5 and a hd7850 (with200GB memory bandwidth and plenty of vram) or a c2quad with an r9 380x it would be the easiest choice ever.
I remember sony proudly announcing the death of pop in with the ps2 launch, and these days it's back with a vengeance.
In the dark souls 3 thread I see a lot of people wish they could play it at 60 fps instead of 30 and it would seem like such a no brainer goal for an upgraded console, but it's not happening if the cpu performance stays the same
