PlayStation 3 Unveiled

The PlayStation 3 was unveiled yesterday afternoon in a press conference at Sony Pictures Studio. The event was full of beautiful demonstrations, specifications, and talk of the games of tomorrow. The machine is certainly impressive, with backwards compatibility, support for up to seven Bluetooth controllers, multiple HD signals, and intimate interactions with the PSP. Coverage, screenshots, and specs available from 1up.com, Gamespot, Joystiq, NYT, Voodoo Extreme, Gamespy, BBC, GamesIndustry.biz, Engadget, Anandtech, Kotaku, Gamasutra, and CNN Money. The only downside I see so far? The controller. Update: 05/18 21:35 GMT by Z : Gamespot has up a comprehensive look at the console based on what is known so far.

    In a bluetooth piconet you can only connect 8 devices. So that means 7 controllers and 1 console.

    I'll boil it down: here's what you need to know.

    * The hardware absolutely rocks. The tech demos they showed off were incredibly impressive, and it's very clear that Cell (programmed correctly) will be the most powerful platform out there.
    * There's already signs of DRM and locking down the platform. There was a slide on "hardware security built-in" (they probably meant the way the Cell protects data when shuttling it off to another processor, but it's easy to get the double-meaning).
    * As it stands right now, this thing is going to blow the doors off of Xbox 360. This is coming from an Xbox fan (I've got 30 titles lined up in the den). I'm a gamer, but I also love the best hardware. Barring what Nintendo introduces (and they could very well surprise us, despite the "graphics don't matter" marketing they've been doing), this is clearly going to be the most powerful console around.

      The Xbox 360 CPU is actually rated at 115-130 GFLOPS depending on your source. A Sony slide at the PS3 unveiling showed it (the 360 CPU) at 115 GFLOPS.

      Don't forget the hard drive: included on the 360, an expansion item for the PS3. You didn't overlook it on purpose, did you? :)

    I very much doubt you will see any games support 1080p at first...and maybe not ever. Why spend the cycles rendering all that extra data that no one is going to see? I suspect that the developers would much rather use those cycles improving graphic quality or throwing more characters onto the screen at once than rendering double the data for no gain.

    Almost no HDTVs support 1080p right now. And if you buy a nice HDTV today, are you going to replace it in five years? 1080p would be wasted on this generation of consoles, IMO.

    What isn't being explained to the uninitated is that line for the Cell on '7 x SPE @ 3.2Ghz'.

    The Cell isn't a single core: it's 8! The CPU (or PU as it is called) is a POWER5 core. It is connected to 7 APUs/SPEs (Attached Processor Units/Single Processing Elements (whatever you want to call them)). Each SPE is a limited CPU in its own right with its own local caches and memory. The PU acts as a controller, dispatching work to the APUs.

    Each APU is essentially a very fast CPU optimized for moving data streams and calculations. Cell was designed to chew on large amounts of similar data very, very fast. It isn't a general purpose core like the POWER or Intel cores found in Xbox 360 or the original Xbox (or your PC for that matter).

    Caches aren't everything. PCs and XBox depend on caches to maintain performance levels as in a mixed instruction stream it is tough to know what's going on. A cache miss in a general purpose core can (and is) expensive in terms of cycles. Cell (and the original PS/2) get around caching issues by simply not having them (or just enough to feed the processor) and rely heavily on moving data across a very wide and fast memory bus on demand, as needed and repeated as necessary. Dramatically simplifies the architecture and permits much more focused optimization of code. Programmers for PS/2 had to learn to live without caches and learn a new way of development since PC experience doesn't translate over into the PS/2 world and clearly not into the PS/3 world.

    A big part of this contest between XBox 360 and PS/3 is seeing how programmers managed to take advantage of that parallel power. Multiple cores in XBox will be useless if they can't be taken advantage of. Same goes for Cell.

    I think PS/3 has the advantage and will eventually win. I'm surprised at the specs as original discussions on the machine had indicated it would be fitted with FOUR Cell processors, not one. Perhaps the initial round of prototypes are single Celled (forgive the pun) to permit development and gaining familiarity with the hardware. Perhaps inside are empty slots for more chips.

    Don't confuse PS/3 with a PC because it's not. It is designed to be a very fast SIMD media machine focusing on graphics, video and audio. It may suck as a general purpose server and perhaps a PC can hammer it on some benchmarks but if Cell performs half as good as the information on it speculates in the media realm, there isn't a PC (or Xbox) out there that can hope to keep up with it.

    Each device can only be Master in one piconet. And last I looked there were no chipsets that handled scatter-nets properly. (Ie having a device be master in one piconet and client in another.)

    IOW if they wanted more than 7 devices they'd need multiple Bluetooth adaptors. And I believe they really don't expect more than 4 players per game. But this allows you to keep other devices (Eye-toy etc) hooked up while you play 4 player games.

    The PowerPC core in the PS3 cell chip is probably not a Power4 or Power5 core. According to this Microprocessor Report article:
    But the team didn't just take an existing core like the PowerPC 970FX and build an SoC around it. The core for Cell is new and appears to have been designed before the clock-frequency-is-dead era. The core was designed to reach certain power and die-size goals and is designed to be able to run at clock frequencies in the 4+GHz range. The engineering theam did simply some of the core design (for example, it's an in-order design and only a dual-issue superscalar) and used some dynamic logic in the design in certain critical timing areas.

    The core complies with the PowerPC instruction-set architecture version 2.02 (and the 2.01 public version of teh specification). The core was designed with a particular balance of die size, clock speed and architectural efficiency that is different from that of PowerPC 970. This instantiation of the Power Architecture still has a relatively long pipeline, much like the Power 4 and PowerPC 970, but the Cell design does not have a very wide issue pipeline or out-of-order execution, nor does it have as many functional units.The Cell Power core has hardware fine grain multi-threading.

    So it looks like the PS3 core is a lot simpler than even the simplified Power4 core in the PPC970. Looks like they decided that instruction level parallelism does not help with game code and went with a smaller dual issue design with reduced number of instruction units.

    This is quite insteresting. Unlike general purpose processors, which are often optimized for a set of specific benchmarks, the processor for a game console is actually designed to optimize the performance for a specific set of applications, i.e., 3D games. The most demanding applications driving the performance of high end PCs today also happen top be 3D games. I wonder if we are going to see a transition to back to simplified cores with higher clock speeds soon. Given the current trend to integrate multiple cores on a single processor die, a multi-core design with a large number of simple, high speed processors would be an interesting design trend.

    The multi-threading feature of the Cell core may be ported over from the Power5 design as a way to deal with memory latency at high clock speeds.

    I think it would be pretty safe to assume that the PowerPC core in the Xbox360 chip is very similar, if not the same design. Here is an IBM paper that shows, at least in the lab, they were able to run the cell processor above 4GHz.

  13. Unreal Tournament demo was real-time. by javaxman · · Score: 4, Informative
    How do we know that Sony is not lying like they did with the PS2?

    While we know there is marketing hype involved, at least one demo was shown to be real-time. From the Gamespot article :

    To show off the PlayStation 3's graphical brawn, Sony showed several game demos, including an Unreal 3 engine show-off of what appeared to be Unreal Tournament 2007. In what must come as a relief to developers, Epic Games' Tim Sweeney was on hand to vouch for the PS3, saying it was "easy to program for" and that Epic had received its first PS3 hardware two months ago. He proved the tech demo was real-time by showing it again and by manipulating the camera and zooming in.

    Why is it hard to believe that Sony, working on this project for the past 3 years or more, might just be able to best Microsoft's 18-month project? It should not be. While the specs might be a tad inflated, it's probably safe to say that the PS3 is a more graphically and computationally capable machine than the Xbox 360. What that means for market share remains to be seen.

    Both MS and Sony are going to be pulling out all the stops. Nintendo is likely to step up to the plate as well. You know what? Competition is good.
