memory bandwidth of original Playstation/PS1 ?

They used a boatload of i860 XPs for the SGI Onyx.

Speaking of the PSone VRAM

I have a question, what type of RAM was used for the PSone VRAM?

 

[Squeak]

My memory is slightly different. From what I remember, System-G was a realtime 3D system developed for broadcast TV applications. KK didn't run the project, but at the time was a researcher in the same division of Sony, and saw the system in action. Supposedly at the time KK wanted to put technology like that into consoles (which were very basic back then) but of course had to wait for his opportunity. The people responsible for System-G eventually turned into the R&D group at SCEI responsible for PS1, by which point KK was in charge.

You are right of course. We probably have the same source (Revolutionaries at Sony).
Does anyone have any info (specs, pics, applications etc.) on System G?
I've searched for a couple of minutes and it doesn't seem like it was a widely used system at all.
All the hits are variations on the RaS text. It seems the system was quite a bit more advanced than it's contemporaries, like the Quantel Mirage.

I get a funny feeling that it was, in fact, literally VRAM. Definitely the right timeframe.

Yes, video ram (dual ported).

That's the one! I meant to attribute the information but didn't have it to hand.

I expect it's one of those things that we'd look at now and laugh at how we ever considered such a thing powerful.

If I am not wrong System Gado was created for making a polygonal face with texture mapping that was put into a TV program (a contest) and Kutaragi wanted to put the technology applied to the videogames.

Well, I for one can be can be impressed and admire what people in the past was able to wring from very simple hardware.
I also quite like the aestetics of (well made) early computergraphics.
Stuff like this is really impressive to me.
