Below is some background on the PS3 RSX 'Reality Synthesizer' via
Wikipedia, as follows:
The RSX 'Reality Synthesizer' is a proprietary graphics processing unit (GPU) codeveloped by Nvidia and Sony for the PlayStation 3 game console.
Unless otherwise noted, the following specifications are based on a press release by Sony at the E3 2005 conference, slides from the same conference, and slides from a Sony presentation at the 2006 Game Developer's Conference.
Specifications:
- 500 MHz on 90 nm process (shrunk to 65 nm in 2008 and to 40 nm in 2010)
- Based on NV47 Chip (Nvidia GeForce 7800 Architecture)
- 300+ million transistors
- Multi-way programmable parallel floating-point shader pipelines
- Independent pixel/vertex shader architecture
- 24 parallel pixel-shader ALU pipes clocked @ 550 MHz
- 5 ALU operations per pipeline, per cycle (2 vector4 , 2 scalar/dual/co-issue and fog ALU, 1 Texture ALU)
- 16 floating-point operations per pipeline, per cycle
- 8 parallel vertex pipelines @ 500 MHz
- 2 ALU operations per pipeline, per cycle (1 vector4 and 1 scalar, dual issue)[citation needed]
- 10 FLOPS per pipeline, per cycle
- Floating Point Operations: 251.2 Gigaflops [(24*16* 550)+(8*10*500)]
- 74 billion shader operations per second [(24 Pixel Shader Pipelines*5 ALUs*550 MHz) + (8 Vertex Shader Pipelines*2 ALUs*500 MHz)]
- 24 texture filtering units (TF) and 8 vertex texture addressing units (TA)
- 24 filtered samples per clock
- Maximum texel fillrate: 12.0 GigaTexels per second (24 textures * 500 MHz)
- 32 unfiltered texture samples per clock, (8 TA x 4 texture samples)
- 8 Render Output units / pixel rendering pipelines
- Peak pixel fillrate (theoretical): 4.0 Gigapixel per second
- Maximum Z sample rate: 8.0 GigaSamples per second (2 Z-samples * 8 ROPs * 500 MHz)
- Maximum Dot product operations: 28.6 billion per second
- 128-bit pixel precision offers rendering of scenes with High dynamic range rendering (HDR)
- 256 MB GDDR3 RAM at 650 MHz
- Access to additional 256 MB XDR RAM
- 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 PSGL (OpenGL ES 1.1 + Nvidia Cg)
- Support for S3TC texture compression
Finally, according to a rumor via
Squarepusher2,
Mathieulh of Gitbrew's (irssi, /connect -ssl irc.gitbrew.org) Sony PlayStation 3 Hacking Team also gave
Durandal the coveted PS3 CEX-DEX.zip file
without permission from PS3 hacker
RichDevX.
To quote: BTW Mathieulh I know you gave
durandal (Durandal Dokuchayev) that CEX-DEX ZIP, that it wasn't you that bundled that up, and you were not supposed to do so either

I know... before everyone blame my post, I m like you!! I HATE cheaters online.
I know we can now hack our PS3, and play games for free ... but when ...
i agree totally also mate but last time i said ps3 was outdated etc i got flamed at.. LOL
For what it's worth the 8000 and 9000 series are the exact same technology and the GTX 400 and 500 series are almost identical in architecture. But the fact of the matter is that it was too weak right off the bat which is ridiculous for something that is supposedly designed to last many years.
At this point the RSX is so old and alien compared to modern GPUs that it's not comparable at all, it comes nowhere near even scratching the surface of how powerful modern ones are. Just look at how hard the engineering team of RAGE has to work and struggle to make RAGE pretty much the only game out there on the PS3 which has both nice graphics and runs at 60 frames a second. It's incredible stress on the developers being limited so much.
Anyway, that's why I believe it's not possible for Sony to delay the PS4 until 2016 as they keep saying they'll do. At latest it will have to be 2013, which in my opinion is already years late.
