"Cell is a revolution, a completely new microprocessor architecture which, while it may take some time to get used to, promises a vast performance boost over today's systems.  GPUs can already run 10 times faster than desktop CPUs, Cell will not only bring similar performance but will do so for more applications andit'll be easier to program.

 

Being produced in large volumes also means the Cell will be cheap.  They will likely see wide spread not just in living rooms but but in the realm of industry and science as well.  The embedded world is much, much larger than the PC world and often imposes stringent constraints on the components used, the same sort of constraints the Cell has been designed for."

CreepyBacon

your fanboyism has really clouded your reading comprehension.

as i am not proud of these sources, since they were too positive, and yet we ps3 owners are aware of the points this source has pointed out, and still found them unjustified.

 your thoughts are enough, i'm not even ranting about anything.

IBM's Roadrunner is currently the world' fastest super computer. "It is a one-of-a-kind supercomputer, built from commodity parts, with many novel design features. It is a hybrid design with 12,960 IBM PowerXCell[6] 8i CPUs and 6,480 AMD Opteron dual-core processors[7] in specially designed server blades connected by Infiniband." The Cell is by Mercury for medical imaging. Toshiba has the Cell based SpursEngine for Video applications.

Yeah, this is from before the PS3 came out, but the Cell has proven to be a very good chip for parallel computing and for super computers. Not quite so much as a gaming CPU. Not terrible, but not the revolution that they talked about.

Cell does not seem like something that would appreciate a low memory environment, it was stupid to put it into a system were it would be fighting for resources. PS3 has the same memory capacity as 360, when you have pushed PS3 to its limit without Cell; where is Cell supposed to get the resources for additional computation? Everything requires memory on some level, you cannot store calculations in the air.

The same way MGS4 was achieved, they made sacrifices somewhere to free up the required memory. What those sacrifices are I cannot attempt to guess until I see the game in action, which is unlikely seeing how I have no intention of picking it up and the genre doesn't interest my brother. In MGS4's case the frequent loading screens tell me they sacrificed level size to free up memory.

The thing is if they are only going to use Cell for visual effects, they might as well of just had a better GPU and avoided all these Cell development difficulties.

There wasn't a significantly better GPU available at the time. Using the Cell gives the developers the flexibility to choose how they want to use their computing budget. Developers can use the Cell for more visual effects (e.g. K2) or to build a more interactive game world with particles and physics (e.g. LBP).

What you just said proves Verge's point even further. They said it would be easy to program for. You (And history) now say its complex to program for, which makes Sony's statement a crock.

I think developers would have preferred ease of development to flexibility, easier development can actually lead to flexibility because you have more time and resources to dedicate. As it stands Cell requires so much effort to get the basics right there isn't room for flexibility for most developers, even Carmack struggles with the thing. In the time it took for PS3 to get Killzone 2 360 has had two GOW games, that isn't good.

I stand by what I said, if they are mostly going to use it for visuals anyway they would have been better off with a better GPU than Cell. PS3 could have easily got a normal CPU out at the time in place of Cell just like 360.

1. Again, there wasn't a better GPU at the time. 2. Insomniac, Naughty Dog, Ninja Theory, Media Molecule, Kojima Productions, Evolution Studios, etc have all produced amazing games on the Cell. I don't think it is quite as hard to "get the basics right" as you seem to think. Certainly not as hard after they have transcended the learning curve. 3. In the same time it has taken to produce K2 we have had R1, R2, Uncharted, Heavenly Sword, R&CF:TOD etc. There is no indication that the length of time it is taking to develop K2 is related to the supposed difficulty of working with the Cell. In fact K2 has been playable in one form or another for a while now.

you keep saying there wasn't a better gpu at the time...maybe your saying it so much to convince your self its been proven time and time again the 360's gpu trumps the ps3's so how did a system released a year earlier get a better gpu? sorry to say but there were gpu's better then the ps3's at the time and in the works at the time, not only that sony could have just had Nvidia make a unique gpu for the ps3 like microsoft had ATI make a unique one for the 360.

 All the companies you mentioned are either 1st party or 2nd party thus receiveing the most funding and Q&A,R&A support directly from sony this might be the key to why their games came out so good.

Sounds like a load of damage control to me, the games you listed are not high utilization so it isn't surprising they didn't take as long. Games that aim to push the hardware on the other hand like KZ2, MGS4 and FF13 take years to come out. I don't think it is even up for debate whether Cell is difficult to use or not, it has been echoed by many developers in a position of authority and PS3 needs special care in cross platform games. Cell is hard to use and even harder to fully utilize, are you seriously questioning the truthfulness of this after all that has happend over the last few years?

You also keep saying there wasn't a better GPU, that didn't stop 360 getting a more powerful GPU for release a year before the PS3 came out. PS3 couldn't access a better GPU because they were silly enough to think they could use two Cell processors, when they realised what a mistake this would have been they quickly grabbed a PC GPU coming out at the time and renamed it RSX. It was a quick fix job, if they decided on a GPU from the start they could have customized something better.

Regardless it's just my opinion that Cell was a waste of time, of money and of effort. Consoles are standardized hardware for the mainstream, they shouldn't be experimenting with new CPU designs before thoroughly testing them elsewhere. I don't see how anyone, PS3 fanboy or not, can attempt to defend Cell's use in consoles at this point considering what it has cost the PS3. If Sony is stupid enough to put it in the next Playstation then they deserve to be abandoned by game developers.

Which GPU is better is debatable. Certainly the RSX has better shader performance (which is why multiplat games like Fallout 3 and COD:WAW have better normal mapping). No matter how you try to spin it there wasn't a significantly better GPU at the time.

Even if the Xenos was the superior GPU it is still a custom part that would not have been available for inclusion in the PS3. EDIT: Have you played Uncharted or Heavenly Sword? The water in Uncharted uses real time reflections, volumetric shaders, and is physically interactive. In Chapter 5 of Heavenly Sword there are 2000 enemies on screen at ounce. All with full physics, AI, and self shadowing. There are only a handful of console games that are that processing intensive.

360 had no problems getting a custom GPU for their system because they planned it from the start, maybe if Sony wasn't putting funding and effort into getting Cell into the PS3; they could have afforded their own custom GPU? One that preferably wasn't using an obsolete shader setup in a system hyped to last 10 years.

At the release of the 360 and PS3 unified shaders were at the cusp of introduction. Besides, its not like it is all roses for unified shaders, there is a trade off: raw shader performance. 136 billion vs 48 billion SOPS respectively in the case of RSX vs Xenos.

Raw performance figures are meaningless if you cannot put it to work mate, that figure difference hasn't changed that the 360 GPU is considered more powerful. It also hasn't changed that unified shaders are now standardised, every single GPU produced for well over a year now are using unified shaders.

It's the flexibility, being able to use 100% of your shading power at any one time is considered better than having higher potential performance. Developers don't care about what is written on paper, they care about what can be applied in the real world. It's the same with Cell, all of that theoretical performance they have written down doesn't matter if it is so difficult to apply it.

RSX has two different types of shaders, even if they perform better at certain tasks than unified; they are still performing a juggling act were some shaders are used and some are not. Using all your available performance with ease is better than struggling to use it with a higher potential peak, the end result is the supposedly less performing general purpose shader gets better performance than the dedicated.

[QUOTE="skektek"]At the release of the 360 and PS3 unified shaders were at the cusp of introduction. Besides, its not like it is all roses for unified shaders, there is a trade off: raw shader performance. 136 billion vs 48 billion SOPS respectively in the case of RSX vs Xenos.AnnoyedDragon

Raw performance figures are meaningless if you cannot put it to work mate, that figure difference hasn't changed that the 360 GPU is considered more powerful. It also hasn't changed that unified shaders are now standardised, every single GPU produced for well over a year now are using unified shaders.

It's the flexibility, being able to use 100% of your shading power at any one time is considered better than having higher potential performance. Developers don't care about what is written on paper, they care about what can be applied in the real world. It's the same with Cell, all of that theoretical performance they have written down doesn't matter if it is so difficult to apply it.

RSX has two different types of shaders, even if they perform better at certain tasks than unified; they are still performing a juggling act were some shaders are used and some are not. Using all your available performance with ease is better than struggling to use it with a higher potential peak, the end result is the supposedly less performing general purpose shader gets better performance than the dedicated.

keep going at it guys!!!.... my knowledge is expanding  :D (and no it's not sarcasm)

somehow ppl fail to realise that

-CELL used in supercomputers is not same as CELL in ps3

-something you can do on cell,you can do 3 times easier on some other processor

- cell is not some "uber non unleashed" thing its just procesor with different architecture which is little more powerfull than competition,but have its disadventages

What a load of crock that turned out to be....

Yeesh Sony, what the hell happened?

The quote says it will be easier to program than a GPU....do you deny that fact?

 

Do you deny that a GPU has better performance than a desktop CPU? Do you deny that the Cell has better (at LEAST peak) performance than a CPU?

To address your questions: The Cell isn't being predominantly used as a GPU. If it's easier to program for than a GPU, it doesn't matter because it's being largely used as a CPU.

I do deny that the Cell has better performance than desktop CPU, particularly when stepping outside the bounds of FLOPS. Again, I deny that the Cell has a better peak performance than more traditional CPUs. There is more to performance than the much ballyhooed FLOPS statistic.

You deny that Cell has better peak performance than traditional CPUs, and thus you fail.

Care to explain why? I wouldn't mind learning a thing or two. I enjoy the tech side of things.

It's the flexibility, being able to use 100% of your shading power at any one time is considered better than having higher potential performance.

It's the same with Cell, all of that theoretical performance they have written down doesn't matter if it is so difficult to apply it.

Using all your available performance with ease is better than struggling to use it with a higher potential peak, the end result is the supposedly less performing general purpose shader gets better performance than the dedicated.

The shader performance is being used and can be seen in mulitplat games like Fallout 3 and COD:WOW and exclusives like Uncharted and R2. I don't think you understand the differences between standard shaders and unified shaders. With standard shaders there is a hardware division between pixel and vertex operations, generally in ratio of 3:1 pixel:vertex. The benefit of this design is that each shader type can be specialized at a hardware level for its specific task affording them better performance(example: the RSX can do 5 shader operations per pipe per cycle vs Xenos' 2). The trade off is that optimum efficiency can not always be achieved (example: in a scene that requires 100% pixel operations the RSX can only use 75% of its shaders, the other other 25% [vertex] lay fallow and do nothing). Unified shaders are more general purpose and are able to do both pixel and vertex calculations. The benefit is that regardless of the requirements of the scene to be rendered the unified shaders can operate at peak efficiency, affording developers infinite freedom in constructing a scene without compromises in efficiency (in regards to the division of vertex and pixel data). The trade off is that the shaders aren't as powerful. There is no "struggle" to use the RSX's shaders, you just have to realize that out of the 136 billion SOPS available, 102 are available *only* has pixel and 34 are available *only* as vertex.

No its the same chip, all taken from the same waffers. Cells with 8 functioning SPUs are used in super computing and medical imaging, Cells with 7 SPUs are used in PS3s and Cells with less than 7 SPUs are used in SpursEngine and Cell-based TVs. Ease is all well and good but I prefer *better*.

Normal CPUs are integer based (0, 1, 2, 3, 4, 5, etc) but the Cell is optimized for floating point (1.5, 3.141, 3.33333, etc). Gaming applications, such as multimedia (graphics, sounds, etc) and physics, require the precision of floating point numbers and the Cell is a floating point monster. Even the most current consumer CPUs on the market can't touch the Cell's floating point performance (granted PC CPU's trounce the Cell in integer options but those kind of operations aren't used as often in a game system).

yes because this generation is over...*rollseyes* There is a 360 exclusive that looks better than Killzone 2., visually and TECHINCALLY... *rollseyes* Your confusing CROCK with COMPLEX, the Cell isn't a familiar PC design..takes time. PS3 isn't going no where for a LONG LONG TIME.

The Cell was supposed to be easy to program for. So if its supposed to be so easy, why are we still waiting? They've had a long long time now :|

Actually, FLOPS represent a relatively small percentage of gaming code (at least those portions that aren't taken up by other susbsystems such as graphics and sound). And general purpose CPUs have floating point circuitry within them, making them adept at floating point operations even though they don't specialize in them. The Cell's smaller "cores" however, are suited only to FLOPS, requiring that all general purpose work be performed on the central core or slow workaround be implemented so they can be done by the RISC architecture smaller cores.

Oh me? I'm not waiting for anything. But the person I replied to told me to wait, so I'm curious as to what we're waiting for as well.

[QUOTE="AnnoyedDragon"][QUOTE="Bauer_24"]

but somehow they did store calculations in the air..... how can something like KZ2 be achieved? 

skektek

The same way MGS4 was achieved, they made sacrifices somewhere to free up the required memory. What those sacrifices are I cannot attempt to guess until I see the game in action, which is unlikely seeing how I have no intention of picking it up and the genre doesn't interest my brother. In MGS4's case the frequent loading screens tell me they sacrificed level size to free up memory.

The thing is if they are only going to use Cell for visual effects, they might as well of just had a better GPU and avoided all these Cell development difficulties.

There wasn't a significantly better GPU available at the time. Using the Cell gives the developers the flexibility to choose how they want to use their computing budget. Developers can use the Cell for more visual effects (e.g. K2) or to build a more interactive game world with particles and physics (e.g. LBP).

Yes there was. The 360's GPU solution from ATI was much more flexible, for one - the generation of hardware it borrowed from off ATi was at a point where ATi's GPU's were much more futureproof than what nVidia was doing at the time.

Anything to do with graphics, sound, physics and collision (the majority of the processing requirements) is going to be/or can be done in floating point. The only thing, that I can think of, that would need branchy interger code is AI. PC CPUs have FPU/SIMDs but they aren't nearly as powerful the Cell's SPUs. While optimized for floating point the SPUs are still capable of integer options. Anyways almost anything that can be done in integers can also be done in floating point.

Yup, once it's standard the lems will poop their pants. Now they're just in denial.
