I was thinking ever since xbone got 360 backwards compatiblity people have asked when will PS4 get it. I believe the reason why it hasn't happened was because PS4 was unable to emulate the PS3, but with the more powerful NEO coming they have finally figured it out and it will be a NEO-exclusive feature much like SNES-games are exclusive to the New 3DS

You need to understand how the Xbox One achieves the Xbox 360 backwards compatability.
Do that and you will realise the PS4 is perfectly capable of emulating the PS3.
Ironically... Before Microsoft announced the Xbox 360 backwards compatability, I claimed multiple times on these forums that it was possible and even gave some technical analysis on how it could be achieved. (I.E. I was right.)

I wish they did, I think it made xbox gold better value for xbox one owners over ps4 owners, because the 360 games are just so damn good sometimes, and playing them on your main console is just amazing.
Anyway, it won't happen, makes me sad. Because it does seem moving from ps4 forward everything in the future will be BC |
Sadly, it also requires significant software engineering, which is Microsoft's Forte' and not Sony's.
The Xbox One's multi-os design lends itself well to how Microsoft achieved it's "Emulation".

That would majorly cut into their PS Now profits, not to mention PS3 is probably very hard to emulate due to it's cell processor.

Ironically it's the PS3 emulator that is farther in development than the Xbox 360 emulator on the PC.
Apparantly "The Cell" is not an issue/argument.

Wasn't the CPU of the PS3 stronger than the one inside the PS4 and wouldn't that make BC impossible? |
No. Jaguar is superior.
Lafiel said:
it reached higher peak performance in a few tasks and the better developers made use of the strengths of the architecture in various ways, so it's probably almost impossible to write an emulator that reaches PS3-level performance across all or atleast a big majority of PS3 games with PS4 or even Neo level of processing power
|
The Cell had great Iterative Refinement Floating Point performance, but that was pretty much it, Jaguar outclasses it.
The Cell wasn't some amazing "Super Computer On a Chip" that Sony's marketing would like you to believe.
You also forget the GPU can also pick up the slack, they have some serious compute capabilities these days. ;)

Emulation is very CPU intensive and the Cell was a beast. I'd be impressed if Neo could get it done but it seems unlikely.
SNES being limited to New 3DS is bullshit by the way. The original 3DS has more than enough power to emulate SNES, those specs should be able to emulate N64 as well.
|
CPU emulation doesn't need to be intensive.
The reason why it "seems" intensive on the PC is because to emulate a CPU architecture a developer will take an instruction, chop and translate it into multiple x86 instructions, which means you require significantly more CPU power.
Sony having intimate knowledge of it's architecture side-steps all of that.
Besides, there are SNES Emulators on the PC that try to be as accurate as possible in it's Emulation and it will bring even a high-end CPU to it's knee's.

Honestly I dont see any value in BC for last gen HD consoles. It's totally pointless and waste of Sony's finances, I still have my ps3 hooked up, ps3 is still getting new games even, why would I want another console to play its games, it's still 720p. If I could get a cheaper PS4 without that BC I definitely would, all their effort should go to make PS4 and its games great.
PS3 BC would only make sense if it rendered the games in higher res and better framerate and Neo won't (be powerful enough to) bruteforce those.

There are advantages.
For one, your PS3 isn't guarenteed to work forever.
And there is the chance for better and smoother framerates which can help with gameplay, there are Xbox 360 games on the Xbox One which are running at full speed which was impossible on the 360.
It also helps keep gamers in the Playstation ecosystem by allowing their games to play on more platforms.

Even the Scorpio wouldn't be enough to emulate a PS3
not going to happen |
You make it sound as if the PS3 was generationally more advanced than the Xbox 360 and thus impossible to do on current or future hardware releases.
That would be highly inaccurate at best.
Soundwave said:
I don't think even Neo can adequetely emulate a PS3.
You're talking fairly radically different hardware ... Nvidia GPU + CELL CPU cores. |
Can you provide a technical reason why it's impossible?
The Xbox 360 is PowerPC based and powered by a VLIW SIMD GPU architecture which is radically different to the Xbox One's x86 based architecture and RISC SIMD/SIMT GPU architecture.
Cloudman said:
No, I doubt that. Wouldn't it need the cell processor thing in the PS3? That would probably make the Neo too expensive then. |
Nope you don't.

Waste of Sony's finances? To the contrary, it could be a revenue stream. If PS4 could play PS3 then they could sell PS3 games to PS4 owners. Much like 360 titles are available in the X1 marketplace. It also makes PS Plus a greater value if those free PS3 games work on PS4. Sony has and continues to push PS1 and PS2 games digitally.
Frankly, many people have been using 360 games on X1. There is great demand for PS4 to do the same with PS3 games. I personally have a backlog of 360 titles and there are a lot of 360 games I want to replay down the road. I like being able to do that on the X1 with features like recording clips and I see a lot of Twitch users streaming 360 games via the X1.
For the past few months we've been seeing 360 games actually performing better on the X1 (improved optimization). Its possible the Scorpio has the power to boost games to 1080p, I just don't expect them to do it.

The other great thing is that all the free games you get with Games with Gold for the Xbox 360 you get to 100% keep and they work on the Xbox One too. :)
If Sony could have PSN free games on the PS3 backwards compatible with the PS4, that would be a massive bonus to the consumer and their growing game library.
