On paper, Sony's PlayStation 4 has 50% more rendering power than Microsoft's Xbox One. How will that translate to real-world performance? How will multiplatform games be affected? The people must know, and they must know now!
Ever the instigator, Digital Foundry has decided to temporarily sate gamers' technolust by creating a set of completely hypothetical spec comparisons. Using PCs with equivalent guts to the two upcoming consoles, DF ran a few games, such as Tomb Raider and Crysis 3, to see how well the machines could maintain a high frame rate. Some numbers are tossed around, big words are used, and an early hypothesis is drawn.
My opinion? It looks like we'll have another PS3 / Xbox 360 situation on our hands -- the PlayStation performance boost is not as drastic and some have made it out to be. I predict multiplatform games will be more or less identical, but that won't stop certain gamers from splitting hairs and claiming unequivocal superiority. I'll never understand those people.
