Just as sony went to the leaders of the chip-making world for its cell Microprocessor,it went to the leaders
of the graphic processing unit(GPU) manufactures for the PS3's graphics card.Nvidia was glad to help out in building what sony eventually called the 'reality synthesizer RSX'graphic unit.
More powerfull than Geforce 6800 ultra card put togeather(and that's togeather,not SLI)
At that time,Nvidia was 7000-series of graphic card and had already come out with the G70 basearchitecture for its premium modle,the
GeForce 7800GT.Sony liked what that-not a future-proof graphic card,for sure,but the company didn't feel the need to do that because of the cell processor taking on a large amount of the graphics processing responsibilities.
The chip was ready quickly,running at a core clock of 550MHz and utilising 256MB of video
memory.Nvidia and sony often touted the power of the RSX by saying it was more powerful than two GeForce 6800 Ultra graphics card combined.
The RSX can easily output resolution of up to 1080p;but an important feature is its upscaling ability.When
you put in a regular DVD or VCD ,the ps3 uses the incoming video data tosend the information to the RSX,which refines the image quality when playing it back,For multimedia lovers and especially fans of old hindi movies,this is a godsend!With the 256 MB of memory here and the 256 MB of dedicated memory on board the PS3,the RAM ps pretty much the only part of the console that is a downer in an otherwise magnifiient hardware setup.
