according to Sony PS4 is about 10 faster than the PS3: http://www.examiner.com/article/ps4-architect-playstation-4-specs-10-times-better-than-ps3 and 43 times faster than the PS2: http://www.extremetech.com/gaming/178181-sony-claims-ps4-is-43-times-more-powerful-than-the-ps2-an-unnecessary-lie-that-perpetuates-the-megahertz-myth
we can all agree that its probably some PR numbers, but real tech specs shows PS4 around 6x faster than PS3, it has about 6x more gigaflops, 6x transistor count, a HD7850 is about 6x faster than a 7800gs, in real life scenarios, while running a PC game with PS3 settings you get about 6x more fps than running the same game with PS4 settings
Naught Dog and Sony claim that TLOU has been fully optimized taking advantage of 7 years of optimization, but lets separate 2 types of optimization
1- software optimization is when developers make a game look better with the same amount of hardware resources, like when people learned they could compress textures,or when they use a 10kb texture of a brick to make a brick wall of 200 bricks, replacing a brick wall that had originally a texture of 2mb, just putting 200 identical bricks, or when 3d graphics engines started to only render the textures polygons.., that are in front of the camera, whithout rendering the graphics that are on the back of the camera,saving hardware resources
this optimization is real, developers do it all the time, and thats why in a console generation, a later game looks much better than a game released in the beggining of that generation
but console manufacturers want to make us believe in another type of optimization,
2- console optimization, or fixed hardware optimization or coding to the metal...
this claims that working with the same old hardware developers can extract more of it by "coding to the metal" or "improving efficiency" and this optimization, unlike the software tricks, cannot be ported to another hardware
this is a good way of selling dated hardware and some sony fanboys already believe that PS4 will in a few years time run games like a Titan Z graphics card, those optimization claims try to make us believe a PS3 is currently running games as good as a PC with 4, 6, 8 ,10 more power than the PS3
but TLOU is going to be ported to the PS4 and only 6 months since PS4's launch ND says it will run in 1080p (2,5 times more pixels), 60fps (2x more fps) and anso "higher resolution character models, improved shadows and lighting, in addition to several other gameplay improvements.", to make this kind of improovement (720p>1080p 30fps>60fps +textures,shadows,lightning) you need about 6x more processing power, PS3 and PS4 have completely different archtectures, if real, all hardware optimization would surely be lost when porting it to PS4
if PS3 is running 4,6,8,10 more efficiently than in the beggining, how the PS4 version is going to have improvements that require also 6x more hardware power?
2 possible answers:
1- Naught Dog had in 6 months of console life cycle just made the same hardware optimization it did in 7 years working on PS3
2- unlike the very real software optimization, hardware optimization is not real and if TLOU were ported to a PC with a HD7850 it would run 6x faster/better, in this case simply porting TLOU to a PC with a PS3 graphics card 7800gs it would also run just like it does on the PS3
IMO the same company and developer that spent so many years trying to make us believe in "coding to the metal" has ironically proven that its not real
