    The RSX 'Reality Synthesizer' graphics processing unit is a graphics chip design co-developed by NVIDIA and Sony for the PlayStation 3 computer console.


    [edit] Specifications
    550 MHz G71 based GPU on 90 nm process [1][2]
    300+ million transistors (600 million with Cell CPU) [3]
    Multi-way programmable parallel floating-point shader pipelines[4]
    Independent pixel/vertex shader architecture
    24 parallel pixel pipelines
    5 ALU operations per pipeline, per cycle (2 vector4 or 2 scalar/dual/co-issue and fog ALU)
    27 FLOPS per pipeline, per cycle
    8 parallel vertex pipelines
    2 ALU operations per pipeline, per cycle (1 vector4 and 1 scalar, dual issue)
    10 FLOPS per pipeline, per cycle
    Maximum vertex count:1.2 billion vertices per second
    polygon count: 450 million polygons per second


    Maximum shader operations:100 billion shader operations per second
    Announced: 1.8 TFLOPS (trillion floating point operations per second) (2 TFLOPS overall performance)[5] [6]
    24 texture filtering units (TF) and 8 vertex texture addressing units (TA)
    24 filtered samples per clock
    Maximum texel fillrate: 13.2 GigaTexels per second (24 textures * 550 MHz)
    32 unfiltered texture samples per clock, ( 8 TA x 4 texture samples )
    8 Render Output units
    Peak pixel fillrate (theoretical): 4.4 Gigapixel per second
    Maximum Z sample rate: 8.8 GigaSamples per second (2 Z-samples * 8 ROPs * 550 MHz)
    Maximum anti-aliasing sample rate: 8.8 GigaSamples per second (2 AA samples * 8 ROPs * 550 MHz)
    Maximum Dot product operations: 51 billion per second [7]
    128-bit pixel precision offers rendering of scenes with high dynamic range rendering (HDR)
    256 MiB GDDR3 RAM at 700 MHz[8] [9]
    128-bit memory bus width
    22.4 GB/s read and write bandwidth
    Cell FlexIO bus interface
    20 GB/s read to the Cell and XDR memory
    15 GB/s write to the Cell and XDR memory
    Support for OpenGL ES 2.0
    Support for S3TC texture compression [1]

    [edit] Press Releases
    Staff at Sony were quoted in PlayStation Magazine saying that the "RSX shares a lot of inner workings with NVIDIA 7800 which is based on G70 architecture. Since the G70 is capable of carrying out 136 shader operations per clock cycle, the RSX was expected to feature the same number of parallel pixel and vertex shader pipelines as the G70, which contains 24 pixel and 8 vertex pipelines. [2]

    NVIDIA CEO Jen-Hsun Huang stated during Sony's pre-show press conference at E3 2005 that the RSX would be more powerful than two GeForce 6800 Ultra video cards combined. [2]

    I'm pretty sure that's the spec for the X360. The PS3 has 1 CPU divided into eight SPEs.
    The reason I asked is that the HD 3870 X2 is able to perform 1+ Teraflops of calculations, almost equal to the PS3's 1.8 Teraflops.

    See, that's your problem. "One man's trash is another's treasure".

    50FPS, by casual gaming standards, it is pretty good. :)

    Yeah so what if it dips into 30... and maybe it hits 70 sometimes. It's still very playable and some people just consider that 'pretty good'.

    One mans trash is a homeless persons dinner lol

    Who cares what people think is 'good', 30fps sucks and is not an enjoyable experience. True, it is the best experience that is currently possible, but it still sucks balls.

    The PS3's graphics chip was built around the G72 Core (Geforce 7800 Series), how the hell does it manage to pump out new generation graphics?

    It's a console. As good as it may be 'for a console', it's no PC performer.

    Really

    "Don't buy it" And you are? You have majical insights us lowly computer users do not have?

    I don't know what he was saying, but can you please use proper grammar?

    Personally, I think it will be better. That is just me, though.
