    Thought I'd start a post for those in interested in the nuts and bolts of the PS3.

    Fanboys, nerds and ramblers welcome.

    Anyone with any news of actual peroformance test of PS3 hardware especially welcome as they appear. Note most of the manufacturer figurs have lots of fudge factors in and are only a guide...

    Sony wanted a roadmap to get them to 1000 times the performance of PS2. They designed the Cell to try and get them the first step which was 100 times more powerful. Will they suceeed...

    http://en.wikipedia.org/wiki/Cell_(microprocessor)#endnote_slashdot20050211

    Capabilities

    * A next generation gaming console capable of rendering games with high definition up to 1080p.
    * Ability to run as a general-purpose personal computer through the use of Linux its operating system and a removable HDD.
    * The ability for the PlayStation Portable to connect to the PlayStation 3 as a video-enabled controller.
    * Twelve simultaneous High-definition television streams for use on a title screen for a HD Blu-ray Movie.
    * High-definition IP video chat.
    * EyeToy interactive reality game.
    * EyeToy voice command recognition.
    * EyeToy virtual object manipulation.
    * Digital photograph display (JPEG).
    * MP3 and ATRAC download and playback.
    * Simultaneous World Wide Web access and gameplay.
    * Hub/Home Ethernet Gaming Network. - Removed

    Central processing unit

    The following figures reflect estimates of performance of the only current implementation of Cell, designed for the PlayStation 3 game console:

    * 256 GFLOPS in single-precision operations @4Ghz. [8]
    * 25-30 GFLOPS in double-precision operations @4Ghz. [9] (probably 26 [10])
    * 234 million transistors [11]
    * 1 PPE with 32 KiB instruction and data L1 cache, and 512 KiB data L2 cache [12]
    * 8 SPEs with 256 KiB local memory each [13]
    * 0.9 - 1.3 V nominal supply voltage [14]
    * 10 digital thermal sensors [15]
    * 5 power management states (Dynamic Power Management) [16]
    * 221 mm² die (90 nm process) [17]
    * Power consumption is unknown yet, MacWorld suggests 30 W, [18] other sources speculate 50-80 W or more. [19] Electronic Design notes that each SPE consumes about 2 W at 3 GHz, and 4 W at 4 GHz. Combining the eight SPEs, the PPE, and other logic, the CELL processor will dissipate close to 30 W at 3 GHz, and perhaps double that at 4 GHz. [20]

    Estimated floating point performance. 2.18 Terraflops (raw figures only).

    1080p (yes, that’s a p) graphics support.

    The Network hub feature (cat5 ports at least) has been removed to reduce costs

    I thought the Hub feature was intact - but the router function was dropped?

    Just found the specs thing again (from E3):

    Communication
    Ethernet (10BASE-T, 100BASE-TX, 1000BASE-T) x 3 (input x 1 + output x 2)


    Is this still the case?

    I've put removed next to it in the list.

    I'll update it if when ommisions or other changes occur.

    From IBM's research paper.

    The Synergistic Processor Element (SPE) is the first implementation
    of a new processor architecture designed to accelerate
    media and streaming workloads. Area and power efficiency are
    important enablers for multi-core designs that take advantage of
    parallelism in applications [2]. The architecture reduces area and
    power by solving scheduling problems such as data fetch and
    branch prediction in software. SPE provides an isolated execution
    mode that restricts access to certain resources to validated programs.

    Here's some crticism of the complexity for balance.

    http://www.pbs.org/cringely/pulpit/pulpit20050217.html

    IF the PS3 is to achieve anyway near Sonys stated performance figures they are going to have to abstract out the complexity. I hope they do!

    Dual head HD support!!

    That would be cool, I need to save up for another RD65 then?

    But seriously this is showing Sony is attempting to see ofthe MCE philosophy head on with it's wide multimedia capability. I could use this with Picture opposite picture?

    Connectivity is good. Anyone got anyu bluetooth 2 devices?

    Graphics quality is now about shaders rather than raw polygone count so it;s these differances which may end up setting relative performance.



    You want the commodore 64 versions it's much better etc.

    Sony dropped two names that see as potential OS for PS3.

    Linux (variant of( and MacOsX Tiger (less likely imho).

    I'm guessing they are looking at the 360 os and seeing what can better it.

    Would have thought that they had this decided already though? I'm sure they do .

    ------

    Actually thinking about this some more, it wouldn't make sense for Apple given that they are moving away from PowerPC to Intel.

    Perhaps that's why it's OsX Tiger rather than any later version? And IBM already has Linux working on the Cell. I remeber Sony always pitching as a possible media Os to compete against MS .

    Either way they have there work cut out, as MS have made a great online gaming hub with Live, and the 360 version is going to be even better, and 360 links to MCE.

    Is that 1080p at 60fps? people never seem to mention frame rate when talking about 1080p. :confused:

    Good question? Anyone got an answer?

    If it shows more resolution then it should take much more processing power.
    Maybe 1080p will be like full scene anti aliasing was in the earley days of 3d cards. ~You could run it, but v e r y s l ow l y.

    I rember trying to do fsaa on my voodoo 2, damn near killed my machine!

    Yeah, This and 360 might make me not upgrade pc in the future for games. Not for 3 + years anyway.

    The PS3 has me very excited with it's potential. Hopefully Sony will start releasing some more info nearer Christmas. Actually I expect they will release some more info near the 360 release date to try and steal some thunder.

    I just read an interesting interview with J Allard (360's daddy) and he made a good point about the PS3 not having propper air flow considering the power its supposed to have.

    Any comments?

    Looks like he's scraping the barrel with criticism! Joking aside it's probably a good question. I am sure that Sony are fluffing some of the performance numbers. Saying that the Cell uses low power due to it dumping a lot of the branch prediction bumf that the normal CPU has.

    I would guess it's a question of how much heat the gpu pumps out.

    They've already confirmed it will perform at around one tflop of system-floating point performance, which is identical to the x360. I'd be surprised if it is even slightly more powerful on a lb for lb basis.

    How can he say things like this when he knows about as much as the next person about the PS3s internals

    True, but by looking at the pics Sony released, we can see that it simply doesnt have any air flow. Its all closed up.

    http://home.btconnect.com/hgi/ps3/ps3-closeup.html

    Only one side of it seems to have a vent.

    He also made a point about the "boomerang" and wether its going to be popular or not. He said he wants to see it being tested and to see people reaction to it.

    It does have some vents.

    If they have a good clean airflow along the inside then theres no reason why they couldn't get a low noise solution in place. Most PC's have loads of crap to disturb the airflow.

    I think if that's the sort of speculation that they make then it shows they are worried. Saying that I get bored of manufacturers trying to bash each other. It portrays badly on whichever company makes the allegations. As we like to say at out software company, 'concentrate on where we shine, not were our competitors are dark'.

    I bought the official xbox 360 mag and it was fully of silly sideswipes at ps3. Fine for 12 year old fanboys but tedious for the rest of us.

    The boomerang controller looks a bit silly in my opinion , a bit bulky to leave lying around but hey ho. Maybe it looks better in the flesh.

    How many more times...

    The controller shown at E3 was a CONCEPT

    Allard and Bach, of Xbox360, are clearly very worried about PS3 - they spend as much time sniping at it as they do hyping their own console. They seem to think they can goad Sony into releasing information on their console earlier than Sony plan to! Yeah, right!

    If Spring 2006 is the launch time, then we are about 6 months away - how much did we know about Xbox360 6 months ago? Not much, so why are Allard et al stupid enough to think that Sony will release information that MS didn't? duuuuuuuuh.

    Allard and Bach have done a great job of putting me right off Xbox360, I just couldn't be associated with a console fronted by these two muppets.
