Latest Change in PS3 Graphics. RSX was downgraded.
Before getting to the main question, we’re reporting the latest change concerning SP3 graphics.
It has been widely reported that the PS3 graphics chip is something like a Nvidia GeForce 7800 GTX based chip, but according to the collected data, as development has been advances at every studio, one part of the PS3 developers has begun to complain about the lack of fill rate performance.
At first, according the development studios which created graphics prototype {i.e. prototype engines} intended for PS3 titles on a PC base, it is extremely troublesome that the performance goes down (literal: does not come forth) when carrying [their software] over to a real PS3. In the case of each studio, it appears that they proceed with a detuning schedule {Comment: this is typical for the Japanese language: they create their own Engrish words. Detuning means making worse, to deteriorate; BTW this was a real bitch to find} of the technical specifications, in which the rendering resolution is lowered and shaders are removed, and that they carry it over to a real PS3 [afterwards].
So what seems to have happened to the GPU with the same base as the GeForce7800 … Mainly three reasons are given.
Concerning PS3’s RSX, although the design is said to based on the GeForce 7800 GTX, the video memory is similar (literal: suitable) to the lower-rank model 7600 due to the 128bit bus connection and the video memory bandwith is narrower (in comparison to the 7800 line). That is considered the first reason.
Secondly, the RSX specs which have been presented to the public in 2005 have been downgraded. In 2005 it was announced that PS3’s RSX had a core clock of 550 MHz and video memory clock of 700 Mhz, but at E3 2006 it suddenly changed and behind closed doors {the literal version here sounds like ass. Thus slightly adapted}it was said that in the final model on sale the core clock would be reduced to 500 Mhz and the video memory to 650 Mhz.
Thirdly, the ROP unit is in fact only half that of the GeForce 7800GTX.
RSX has 24 pixel shader units just like the GeForce7800 line, but the ROP Unit (Rasterize Operation Unit, also called rendering back-end) which writes(literal: fills) the output from there practically (alternative: virtually) in the video memory as data (basically, drawing the pixels) is different: Instead of the 16 units of the GeForce 7800 line, RSX has only half of it, 8 units. That is exactly similar and corresponds to the lower-rank model GeForce 7600.
[Rest is blabla]
