rumor: Revolution Hollywood GPU based on RV530

these guys are saying (take it as a rumor) that Nintendo Revolution's
ATI 'Hollywood' GPU is based on the RV530 GPU (aka Radeon X1600)
which is a midrange GPU in the PC world.
this *would* be conciderably better than an overclocked Flipper.

the PC version of the RV530 has:

157 million transistors
-5 vertex shaders (geometry engines)
-4 pixel pipelines (render back-ends aka ROPs)
-12 fragment shader / pixelshader units (not 12 pixel pipes as some
websites say)
-4 texture units
-shader model 3.0 capability


by comparison, Flipper (Gamecube GPU) has

51 million transistors total, which includes an audio DSP and about 26M
transistors worth of embedded memory. less than half of the total 51M
transistors are for the 3D rendering core, which has: 1 DX7+- class
geometry (T&L) processor, 4 simple pixel pipelines, 1 "4-in-1"
texture unit (the TEV) and no real true shader capability.


if Hollywood is based on RV530 and is not stripped down in anyway, we
are looking at a GPU that is 5-10 times more powerful than Gamecube GPU
and several times more powerful than Xbox GPU, although still not as
powerful as Xbox 360 GPU or PS3 GPU. It would mean Revolution
graphics would not be massively outclassed by Xbox 360 or PS3, but
still lower overall.

with that said, I am not yet willing to believe Hollywood is based on
RV530, but rather, I am still assuming it is a beefed up Flipper with
higher clock and maybe a few modern pixel shader features.

not enough proof yet for me to believe that Hollywood is based on
RV530. however, admittedly, it makes alot of sense that Nintendo is
getting a variant of RV530 as it's a very good low-cost GPU.

sorry i completely forgot to post the link to where this rumor
originated from!

The source provided the following information under conditions of
anonymity, as well as some other general Revolution statements:

- "Hollywood" is based on ATi's RV530 GPU
- The GPU has been optimised significantly (more on that below)
- The graphics are not as bad as IGN might make them sound
- The Revolution's RAM, whilst being around 128MB, is highly optimised
__________________________

It could be either one of the two or perhaps something else. For now, its
doubtful its an overclocked Fipper as if it was then Nintendo wouldn't have
withheld it from the DevKits.

Oh! Monseur, you are spoiling us with your utterley meaningless
techno-babble!
