Bus Bandwidth of the Sega Saturn

[Ryott]

Hi, I'm new on the forums.
I'm on a project regarding the 32BIT consoles.
I can't find any info on the internet about the Saturn's mem. bus bandwidth.
Anybody can help me on info? Thanks.

Which bus?

I can't find any info on the internet about the Saturn's mem. bus bandwidth.

Geez, it had SO MANY buses, memory or otherwise... That question is almost impossible to answer! To my best knowledge though, the main CPUs ran at 28MHz (geez! sounds TERRIBLY slow these days, almost like a joke in fact) and had one 32-bit bus interface that they both shared for roughly 112MB/s theoretical peak data transfer rate. Unless the bus and/or main memory ran at half clock speed of the CPUs or some other voodoo magic like that - which wouldn't really surprise me I might add. Saturn was a totally crazy machine.
