I'd be disappointed that they didn't find a way to make BC with PS1 and PS2 games from a disc happen. Now if that happened.... I'd be all aboard the ps4 bandwagon.

Where is the full interview? Best I could find in something from 2003, over 3 years before the ps3 even came out and when it came out it was backwards comparable, after losing billions and the ps3 was selling less than the ps2 was selling after launch, I don't find it reasonable to hold one man's possible poorly translated statements against an entire company. I hope you hold yourself to the same high standard and never say anything you'd have to take back no matter how circumstances change. |
Add to the fact that a modified PSX CPU sits in the PS2 for BC, and can also be used for PS2 games...
| JustBeingReal said: Getting PS3 games to run on PS4 isn't impossible, it's just a very complicated process and would require a fair amount of work. 1st of all you have to deal with the core issues that the PPC in PS3 uses RISC assembly language and the SPEs use it's own custom assembly language which is called ISA. The code that runs on both of those processors in PS3 would need to be re-written or recognized as X86 on PS4. PS3's SPE code could be offloaded to PS4's GPU in Backwards Compatibility, leaving a substantial amount of overhead CPU available for any tasks that need to deal with PowerPC processes. PS4's GPU is substantially more powerful than the RSX. Overall Sony could very likely write an emulation environment, basically a virtual PS3 to run on PS4's SOC. Emulation handled in this way isn't the only possibility, Sony could re-write each game that users request, place a patch on servers for users to download when they're connected to the internet, though this is likely the more time consuming possibility. I don't see why The ICE Team or some other development team that is familiar with PS3 and PS4 hardware, OS and APIs in both systems couldn't make a truly virtual PS3 that can run on PS4, it all just depends on whether Sony wants to make this work or provide the resources to make it happen. Backwards Compatibility doesn't get in the way of PS Now, because the whole idea of PSNow is to be used as a rental service for people that don't own all of the games in the PS3's library or even for people that never owned a PS3 in the first place. BC could allow Sony to sell more PS3 games, if people want a superior experience then the remasters and remakes will also sell, so really it's all money for Sony. As for my reaction, I'd be impressed that Sony were willing to put the resources into this, though it's not impossible despite what some claim about this. |
The PS4 is not powerful enough to emulate a PS3....... Even the PS4 GPU would severely struggle to emulate the PS3 GPU 1:1 (very possibly not even possible) and you are talking about offloading to the GPU?

So PS3's Cell Broadband Engine is 4Ghz and the PS4's is 1.6Ghz? So I guess that's why Sony wasn't concentrating so much on BC, right? |
CBBE in the ps3 ran at 3.2ghz, but comparing just operating speed numbers is the absolute most basic way of looking at it.
CBBE can handle specific computational processes faster than the PS4 can, thus emulating it , while essentially possible, would still result in a large portion of games running at a much slower speed, if they ran at all.
If the PS3 had been given a better GPU and more memory it would have easilly outperformed the 360, WiiU and likely given the Xbox One a run for it's money.
People seriously underestimate how good the CBBE really was, it was just nerfed in its implamentation because of the lowly RSX and split ram / low amount of ram.

the PS3 GPU was a piece of shit frankly, it's the CPU that did most of the work, as it was adaptable enough to handle GPU instructions as well as CPU.
Read my above post.
| Dr.Henry_Killinger said: Its not that simple. Let me complicated it for you. I don't have specs, but I don't need those I have logic. A common misconception of CPU's is the correlation between power and speed (clock rate). Clock rate only increases power, if the faster cpu executes more instructions in the same amount of time as the slower one. This is hard because complex instructions typically take more time. The PS3 cpu was not only fast, but able to run complex instructions fast cause of proprietary shit or something. Point is, trying to emulate that is going to take a cpu that is basically just as fast or at least specialized, a near impossible task when also trying to change the architecture, decent emulation of PS3 games would need a top tier PC, in a console its a pipe dream. However, emulation is not the only way for backwards compatibility, XB1's backwards compatibility for instance, is not emulation. |
PS3 was the last in a long line of games consoles to feature bespoke, 'exotic' hardware - in this case, the Cell processor with its ultra-fast satellite co-processors - the SPUs. The general direction of hardware design in the industry has moved away from those ideas - the SPU set-up is almost completely alien to the way CPUs are made these days - so while the PS4's processing cores are relatively capable, emulating the SPUs in real-time would be a colossal undertaking from an engineering perspective. In part, this explains why Sony undertook cloud streaming with PlayStation Now - getting that to work was challenging enough, but I suspect it's a more straightforward task than running six 3.2GHz SPUs on a low-power 1.6GHz x86 cluster.

I agree with that but there is no way the PS4 GPU could emulate the PS3 GPU. It just is not a large enough jump over it. But the PS3 CPU would be the main problem as the PS4 CPU is basically equal to the it in terms of raw capability.
Also on your last post the small amount of ram was the PS3s biggest flaw
ill tell you one thing. it will give me a reason to turn on my PS4 which has been dust magnet most of this year

I'm not talking about emulating it on PS4, I'm talking about emulating it in general.
('_ ') don't throw some source at me like I don't understand. Bolding the words "Exotic", "Ultrafast", or "Collasal Undertaking" is just fluff
All you need to know is 6 3.2 GHZ to 1.6 GHZ x86 cluster. Different instruction sets means the disparity is a lot worse then just a "Generational Gap"
Moore's Law is a myth so even getting 3.2 GHz in normal consumer chips is implausible.
However, BC compatibility can be acheived via the MS method.
In this day and age, with the Internet, ignorance is a choice! And they're still choosing Ignorance! - Dr. Filthy Frank
I really wouldn't care. I bought my PS4 to play PS4 games.
For the record, my PS3 is full BC, and I only played PS3 games on it.
