Thanks for the answer , i didn't know ps4 & xbox 1's GPU are so poor and weak !
i mean 7850 ?! that's so cheep i dont know why dont they put something better in ps4 because seriously that cannot handle any next gen games !
Well, they're not weak either; not in the slightest. They're good GPUs, but up against a $400 monster there's no comparison nowadays. I mean, saying that they "cannot handle any next gen games" is a paradox, since in fact
they are what define "next gen" consoles. If they were sporting the same hardware as a Nintendo 64, then next gen games (assuming developers and audiences didn't get up in a riot) would be built to run according to the limitations of that hardware. They are the standard for gaming right now, not PCs. But regardless, the hardware they're sporting is leagues more powerful than previous generations.
Battlefield 3 on consoles ran at 1280x704 with a pathetic form of Anti-aliasing and it had nosebleeds trying to hit 30 fps with settings lower than the PC's lowest quality settings, and couldn't handle more than 24 people playing. Battlefield 4 on next gen consoles will be running at 60 fps at what we can guess will be 1280x720, with some form of AA, and will still have 64 players at probably medium or high settings. Also don't forget that Battlefield 4 is a hell of a lot more demanding than BF3 was. On BF3 with my GTX 770 I've played around 21+ hours on 1920x1080 Ultra Quality with 4x MSAA, and I can count the number of times I noticed dipping below 60 fps on 1 hand.
For the GTX 770 on BF4, 66 fps is a really good average, but in BF3 I never even dipped below 50 fps at significantly higher settings (4x MSAA) and it was extremely infrequent. Battlefield 4 is very demanding, so even at 1280x720 it's impressive that consoles will be able to handle that at (a consistent) 60 fps especially compared to last gen.
