More on the PS3’s Cell | PS3Blog.net

Jon, a reader who owns Taipei Gamer,Cell has an article looking at the Cell being used by the PlayStation 3:

There is more than one way to look at programming complexity. Sometimes abstractions that make certain tasks easier make others more difficult. Specifically, abstractions in programming languages/models can often be a double-edged sword, and nowhere is this clearer than in runtime performance. The Xbox 360 adopts the traditional abstractions of multithreaded software development. This model is familiar, but is very difficult to program efficiently. The PS3 opts for a fundamentally lower-level model which could potentially put fewer barriers between software engineers and theoretical performance potential. The PS3, powered by the Cell processor, should overcome the obstacles presented by its unique architecture and easily take the performance crown in the coming generation.

It’s a great article, you might like to take a look:

  1. You people do know that the PS3 will have a 65nm at launch.

  2. Do you have a source for that Guy?

    iDon’t buy any of this garbage. There have been so many similar posts in various outlets that study and attempt to compare the various constituent parts of the CPU & GPU in the X360 & PS3 and their interrelationships in making up the whole respective systems. There have been comments from industry veterans who have traditionally been primarily supportive of Sony making statements -on record- that the PS3 advantage is not that greater over the X360; if any at all. Somewhere else, another developer was quated stating the the X360 GPU is capable of superior gfx ‘cuz its unified architecture permits more shader operations when programmed “correctly”. I’ve read these same points elsewhere exept substitue X360 were there is PS3 and vice versa.

    The PS3 Cell has higher performance ceiling my ###. A lot of ppl, including the author, seem to forget that those fancy numbers Sony has qouted in its specs r the sum of ALL its components. Of that lovely 2Tflop figure that is so popular, only 200Mflops is actually from the Cell. The Xenon flop rating is about 400 (add 697 for the GPU and u got 1Tflop plus change for the X360). Looking strickly at the numbers that r exlusive to this 1 component, 1 can understandable conclude that the X360 has the better CPU.

    The verisimilitude of these figures lack certainty and meaning cuz the manufactures r always engaged in some kind marketing ploy to appease to their target markets and fanboys like this idiot author can easily manipulate the numbers to bolster the position of their preferred product; in this case the PS3.

    Let me demonstrate something. The X360 has about 305GB of memory bandwidth compared to the PS3 51GB. Damn, right? What many haven’t realized is that 256 of those gigs exist exclusively between the GPU and its’ daughter die.; not between the primary RAM and any components.

    The reality is that these products will be right on each others tail. Developers r cutting costs by using middlewares and other tools across all platforms. Any noticable audiovisual advantages in games for the PS3 or X360 will come from 1st party developers and publishers. Companies like EA don’t care if their title looks better on system A vs B. They’ll make the exact same product using the same tools and put it on the shelves usually on the same date to make money not to give the little fanboys ammunition against their rivals.

  4. Who really cares which machine has the better specs!?

    If you buy a PS3 or 360 then all that matters is the quality of the games. Right? Right?

  5. To Gary: Absolutely. The quality of the games is what matters. However, I think that the 360’s programming model is more likely to introduce hard to find bugs. The PS3 does have its own challenges to overcome though.

    I resond:

    Well, first of all, I didn’t quote performance numbers anywhere in my article. My statement about Cell having a higher performance ceiling is mostly a reference made to comments by Carmack and others that it does. Of course, most also think that it will be harder to achieve max performance on the PS3 than on the 360, and that is where I disagree. In fact, my argument is really at the software level, because hardware wise they are both really powerful. It is the consequences of their different CPU architectures that gives Cell the advantage in my eyes. Granted, this is really just an educated hunch.

    I do agree that 1st party games are where you will see if one console is outperforming the other. It is likely that most 3rd party games won’t make the most out of either systems hardware. However, in the current generation, that hasn’t stopped 3rd party Xbox games from looking better than 3rd party PS2 and GC games. Also, in my article I make the case that the most popular platform may see more attention from middleware developers.

    Thanks to everyone who toook the time to read the article.
