- This article is about the graphics chip. For other uses of RSX, see RSX (disambiguation).
The RSX Graphics processing unit is a graphics chip design co-developed by NVIDIA and Sony for PlayStation 3 computer console.
Technical Details
- Clocked at 550 MHz
- 1.8 TFLOPS (trillion floating point operations per second).
- Multi-way programmable parallel floating point shader pipelines
- 136 shader operations per clock. It should be noted that will contain only 8 ROPs as opposed to G70 , that contains 16 ROPs.
- Transistor count of 300.2 milllion transistors
- 74.8 billion shader operations per second
- 33 billion dot products per second
- 128-bit pixel precision offers rendering of scenes with high dynamic range imaging
- 128-bit memory bus width , as opposed to G70 with a 256-bit bus width
- S3TC [1]
- Over 1.2 Billion Vertices per second. (Possibly around 370 Million Polygons (Triangles) per second)
Press Releases
Staff at NVIDIA 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 is expected to feature the same number of parallel pixel and vertex shader pipelines as the G70, which contains 24 pixel and 8 vertex pipelines.[citation needed]
RSX will be clocked at 550MHz, which is identical to the older G70-based high-end 7800GTX 512 MB (550MHz), and significantly lower than the current G71 architecture to which can achieve clocks of 650 MHz (featured on G71-based 7900GTX) or more.[citation needed]
NVIDIA CEO Jen-Hsun Huang stated during Sony's pre-show press conference at E3 2005 that the RSX will be more powerful than two GeForce 6800 Ultra video cards combined.[citation needed]
