25MHz infact.

33Mhz MIPS R3000

Two MIPS processors running at 25MHz with GFX integrated on one of the chips.

No - only one.  And a GPU (Graphics Processing Unit) and a GTE (Geometry and Transform Engine) for doing 3D calculations.

 If that doesn't ring a bell, then you really don't know anything. It's a multi-processor chip harbouring about eight processors each.

No it isn't.  It's a single CPU.

The 250MHz PS2 Kicks the balls of both PPC and x86 so hard that the nuts will end up on the moon.

293Mhz MIPS R5k... and no it doesn't.  Its nowhere near as powerful as the AmigaOne, Pegasos, or XBox or GameCube for that matter.

HAHAHAHAHAHAHA!

That was funny.

The PS1's only performance comes from a pair of MIPS CPU's.

It doesn't have a pair - it has one MIPS R3k @ 33Mhz.

 It doesn't have a 3D chip, only RAW POWER strait through

It does have a 3D chip - the GTE.  This is what gives it the power to do 3D graphics as the main CPU is very very slow.  Try writing a 3D game on PS1 using only the R3k and see if you can hit 10fps...
It also has an MDEC decompression engine for movies.

. It's like having a Matrox board integrated on the same chip as a PPC with full parallel blast between them. And then you scare it up to 16x250MHz (16 processors, distributed over two chips), and do some finetunes to get the PS2.

Erm... You really haven't a clue what you're talking about have you?

Note: PS1 games looks like CD32 because it only have 5MB (unified) RAM available for games. Therefore most gfx is 8-bit with 32-bit (rgba) gfx effects ontop.

PS1 has 3.5MB RAM in total and it isn't unified.  2MB main RAM, 1MB video RAM (for frame buffers and textures) and 512k of SPU RAM (for samples).

PS1 games are nearly all in 16bit colour.  Textures in PS1 games are usually 64x64 pixels in 16 colours (4 bit CLUT) as this happens to fit exactly in the texture cache (and also the amount of VRAM is very limited).

Keep it up Dude !

Do you know the Game Cube PPC & GFX Spec ? :-D

As it happens theres a GameCube devkit about 8 inches away from me :-) It's not mine, unfortunately (I'm working on PS2, for my sins).

Cube has a 485 MHz custom IBM PPC CPU and a custom ATI "Flipper" (in keeping with the dolphin theme) graphics chipset.  The graphics chipset can't be equated to anything on ATI's PC graphics cards - it was designed specially.

 It was actually designed by a group of ex-SGI employees (many of the same people who worked on the N64) who founded their own company called ArtX, which was later acquired by ATI.  Not sure if I can go into detailed specs as much of it is under NDA but it is very powerful.

Lando: I don't think there's a single accurate statement in your post. I've actually opened and checked the contense of my PS1. And read information from both MIPS and Sony. Where did you get that faulty information from?

I'm a professional games coder.  I've worked on two commercial Playstation games, one XBox game, and am working on my third Playstation 2 game.  I've also attended the last three Sony developer conferences.
