I think the PS2 graphics chip had an immense fill-rate, not rivaled even by current graphics chips (I could be wrong, but this is what I remember).



Why rely on memory when the truth is two Wikipedia searches away? PS2 graphics chip comes nowhere close to any modern GPU. GPUs have progressed a great deal in the last 12 years.

Also, rating GPUs based on their pixel fill rate stopped making sense around a decade ago.


I think it was the eDRAM that made difference, allowing lots of transparent redraw to be handled: "Embedded DRAM gives 48 GByte/sec memory bandwidth to eliminate pixel fill bottleneck." - http://research.scee.net/files/presentations/agdc2000/ThePow...

Granted that was years ago, so I might be mistaken. But it's still a lot of speed for a device that was made more than 13 years ago...


And you are right that they come nowhere, but if the game relies on one specific feature and over-used it, and that feature is a bit slow on modern cards - then it's an issue emulating it.

No wonder the first PS3 came with the Synthesizer chip built-in, rather than emulate it.


its not the fill rate/memory bandwidth but the incredibly low latency of the entire GS pipeline (which you cant get without edram) that makes it difficult to emulate.
