    Out-of-order, base architecture is from 2010, 28nm fabrication process, has some performance/complexity tradeoffs to reduce power consumption and die size (down to 3.1mm^2 from 4.9mm^2) as Jaguar is designed to give tablets a big performance increase, more instructions than previous low-power models (SSE4.x, hardware AES and more), increased floating-point performance over Bobcat, and AMD claims ~15% instructions-per-clock gains over bobcat.

    So from the Jaguar architecture, AMD is building two main cores.
    • Kabini is for the desktop market and there's already model specifications out there, all with "AMD HD 8xxx" GPUs integrated. The 8xxx series supports Directx 11.1, OpenGL 4.3, and OpenGL ES 3.0 (insert Dolphin mention here). The current models do not have Turbo enabled, though Jaguar itself supports it. TDP is 9-25W.

    • Temash is the second core built off Jaguar, and created for low-power environments. TDP is 3.9-9W, one of the publicly-available models will have Turbo (can clock up to 1.4ghz from 1.0), and Temash can be dual or quad-core.
    As for the specific models and setups that the PS4 and XONE are using, both of them are using 8 core setups... which means that both of them are using two Jaguar units, a multi-CPU setup (rarely seen outside servers/farms and the failed Skulltrail). Since sharing data and processes across two different CPUs is a different and more taxing/limiting process than sharing across cores on one physical CPU, it seems that one of the four-core CPUs will be used for the main program and/or games, with the other four-core CPU used for overlays, background processes, possibly additional hardware control, etc.

    And here's the chart most people have more interest in...
    [​IMG]

    The architecture used currently clocks up to 2.0ghz, most rumors point to clocks of 1.6ghz for both the PS4 and XONE. The PS4 and XONE seem to have similar or even the same CPU specs, but as we've already heard the PS4's going to be using way-higher-clocked RAM, and 50% more GPU cores.

    If we knew the specs for the various AMD HD 8xxx cores then we could possibly figure out the closest CPU models for the PS4 and XONE and fill in the missing specs on both sides, but that info doesn't seem available just yet as the cores only commercial launched yesterday, it'll take time for the CPU-Z and GPU-Z databases to mark all the exact differences between the models... and that also assumes that the PS4 and XONE would be using the integrated GPUs and not a separate dedicated chip (the XONE motherboard appears to have no expansions cards so the GPU is either the on-die CPU one or somewhere else on the motherboard).

    Also for anybody that's still holding out hopes for 360 BC on the XONE...

    Soo, the XOne is just an underpowered PS4 with more fees attached?
    Why would I want this thing again?

    It needs some REALLY good exclusives to attract any customers.

    MS wants the Xbox One to be an all-in-one system, eliminating everything in the living room but the Xbox One and yet they force users to use the Xbox 360 along with the Xbox One. All-in-one, not so much.

    If it costs $100 less and the two systems continue to share, like, 80% of their total game library (withholding exclusives), I don't see why someone wouldn't, so long as the games aren't perpetually priced as high as possible (Xbox is looking a lot like how Origin...).

    I'm actually super interested in what the launch prices will be. If they're high enough, it might end up that getting a gaming PC would be more economic than going with a dedicated console. Sony at least is looking to offer exclusive games worth getting on their systems.

    I don't have an XBOX 360.

    Is there something wrong with me?

    not at all, all what you need is a PS3 and a tuner(all tv's have it conveniently integrated) for have a multimedia center that plays bluray, digital movies, music and AAA games, you can add a Wii(U) for retro gaming, also if you want digital tv, providers give you a digital box when you purchase his services, and with a free remote control!! no need to talk to your electronics!!!.

    Nope, you passed the health check. Can't say this about the 77.2 million Xbox 360 buyers yet.

    As far as I know, both CPU's have been customized by AMD - comparing stock values is a little bit of a stretch since we don't know what kind of add-ons Sony and Microsoft chose for their versions. All we know right now is that both are based on AMD Jaguar, but by itself that doesn't mean much. ;)

    So was partially the 360. didn't you read how microsoft paid IBM for their part of the research used to make the ps3, to make the 360? I posted it back when I first joined.

    The sources include an XONE teardown and info from suppliers, which is why I included the actual numbers.

    Some numbers in the PS4 are missing due to the lack of a physical teardown, though.

    this...
    the X360 cpu is a beta version of the PS3 Cell, Microsoft rushed the launch of his console and used the beta stage cpu even when was poor version of that hardware, but in that version of the consoles war the X360 has a better GPU that was easy to program for developers. the PS3 RSX is not as powerfull as the X360 ATI card, but the Cell can handle all that the RSX can't and help in the rendering process, that's why ports sucked in the other console when where fully developed on one then ported to the another, like Bayonetta and Final Fantasy XIII.

    now is a very similar scenario, only that the PS4 has more powerfull GPU, by the rumors anyway.

    So Rydian, would this mean next gen games would be able to run on PC set ups with the same specs? Or is there some kind of super optimization that has to be done?

    If it is two dies I wonder if things will be merged onto a single one in later life like some of the server chips. We have already seen marginally variable devices hit and refinements made but this could be quite interesting.

    The low power stuff caught me a bit off guard though, it seemed like consoles were heading higher and higher there for a while.

    They wouldn't be for the same OS so they'd need to be virtualized at the least, emulated at the worst.

    EDIT:
    Well this is "low TDP" in comparison to PC stuff.

    There's so many words I don't understand here. Can't we just say it's pixie dust and call it a day?

    ...the two processors are nothing alike in the grand scheme of things? Work on the Cell began back in 2001 and it was backed by Sony, Toshiba and IBM themselves, the idea was to create a central processing unit supported by specialized cores around it, hence the PPE+SPE combination.

    Microsoft took no part in its creation or design - the Xenon CPU cores are merely based on the modified PPE. It doesn't make it a Cell processor or its "beta" - the PPE is just a normal PowerPC core. The whole point of the Cell was the introduction of the SPE cores, not the central PPE.

    ^^^^^^^^^^^

    I think the point he was making is the 360's cpu is it based on unrefined and unfinished work. The rest of his statement is dead on of what happened with the 360.

    Handheld = Designed for lower power consumption to conserve battery -YAY!

    Console = Designed for lower power consumption to...I don't know why. Its connected to mains power! Overclock the hell out of it for Christ sake!
