    "The biggest adversary in our life is ourselves. We are what we are, in a sense, because of the dominating thoughts we allow to gather in our head. All concepts of self-improvement, all actions and paths we take, relate solely to our abstract image of ourselves. Life is limited only by how we really see ourselves and feel about our being. A great deal of pure self-knowledge and inner understanding allows us to lay an all-important foundation for the structure of our life from which we can perceive and take the right avenues.”

    I don't know what the hell it means but the wording sounds good. From what I'm understanding this basically means even more freedom for devs. That can never be a bad thing. Come on Holiday 2013!

    Sadly my expertise doesn't go deep into the inner workings of execution side of things. (RISC, SIMD.. etc.)
    I do know some generics though.

    Compute & GPGPU and are terms that mean just that you give code to GPU and it does the calculations.

    First GPGPU attempts used standard pixel/vertex pipelines to compute what they wanted. (IE. some ps2 games rendered polygons on top of each other to get complex computations from add, sub, mul blending modes.)

    Today we have OpenCL, Cuda and such which give access to write 'normal' code which GPU executes.
    You can code 'hello world' or what ever you want and GPU calculates it. (There are no limitations.)
    Thing is GPUs are horrid in some types of code (Single thread spaghetti) and are slower than any CPU so it's not feasible to use GPGPU for everything.

    It's good news that Orbis & Durago use as new GPU architectures as possible as they offer more flexibility and ability to do more work per watt.
    If one wants a sample what GPUs are used for, the good place to start is to see some presentations from GTC and check CUDA showcases.

    Here's also a tech talk which explains little on future on where we are going.. (I'm pretty sure it describes Maxwell coming out around 2014..(highly recommended))

    Indeed, I maybe off base here( its feels like a new world to me each gen especially when things change and you don't pay attention, it like a forgotten language but once you understand its based off something else you start to understand it better, but I'm no mynd or jilippone)
    But the GPU has we know so far would have to change, the Ram type would have to change, the current rumoured OS setup would have to change
    Even if the 720 had 16gbs of Ram it would still have trouble
    And this ESRAM really looks like a bandage at the mo, I can't see MS coming to the table with the specs we currently know
    On paper they look similar but they really not, not for developers anyway

    I'm sure that Microsoft has something similar on Durago.
    This is also outside topic though..

    I like the fact that the GPU is custom made by AMD and is based on the Radeon 7000-series desktop graphics cards. Having the processing power of 1.84 TFLOPS it sounds pretty good to me.

    Remembered an old little shader competion where there was one of the first 'proper' GPGPU demonstrations.
    One entry is a Frogger game done with shader model 2..

    Overview: "You've run the program, I assume, and so viewed the magnificent earth-shattering graphics -- at least for the early 1980s. This program isn't about fancy graphics but about showing the computational power of pixel shaders 2.0. All the game logic is in pixel shaders; the C++ code just performs initialisation and stores the time and key press in constants for the shaders to read."

    Latest findings show that the GPU is actually based on AMD's next series, the 8xxx (8770 most probably) based on GCN2. From what i've read and understood, the improvements made in GCN2 improves the efficiency of the GPU considerably. So in conclusion, even better than what we originally knew!

    I thought the dedicated CU idea in the GPU had been debunked in favour of the standard 18 CU design we have that the developers can allocate rather than having a segmenting processing system.

    Happy to be corrected mind you.

    If developers choose to use computing power for hair, of course.

    Remember those Nalu & Luna demos from nvidia when 6xxx and 7xxx series launched?
    Theoretically a developers could have done quite decent hair even on this generation, but they decided to use the power to get decent characters and environments instead.

    Decent characters ... as what exactly? The hair in that comparison screenshot jumps the quality from average looking to CGI looking. That's the impression i'm getting. Having realistic hair is the next big step in character improvement towards immersion imo!

    Correct, this appears to be a GCN2 card.

    And thats not Nintendo Gamecube 2 card, just incase lol


    Also from the PS4 specs the bandwidth on offer is higher then a 8870, add the GCN2 architecture and we are looking at something in the Highend range, not 8970 highend lol but obviously it is higher then a high mid range
    how much I don't know

    I usually tend to look at the water effects to see if they can make the behavior of water more realistic, which still hasn't been done yet but I can see that being harder than hell. If you look at the start of the video of Watch Dogs for the PS4 event, take a look at the boat in the beginning that is going under the bridge. Okay, now look at the water effects of that boat, that is the behavior I want out of water effects. The PS3 doesn't even come close to that...

    here... It shows the boat right at the beginning, but sum seconds in it shows it again and you can really see the water simulation effects...

    At least AMD did it right TressFX isnt GPU vendor specific so more and more devs may include it in their games because more gamers gets the benefit.

    Direct compute I think is part of Direct X so on a PS4 might not be likely.
