I'm not sure how fast a 25mhz 68030 can move data from Fast ram to Chip ram. Let's say you want 15fps (a very acceptable speed, in my opinion). That would mean it would need to move 1,155,000 bytes per second, in addition to whatever else it is doing. Remember that Chip ram is 'slow' ram, in that it cannot be accessed by the 68030 every cycle; it is locked out for the custom chips to do their thing from time to time; maybe that is one limitation? On the A2000 it is also only 16bit ram, while your Fast ram is likely 32bit, correct? Can a A2000/25mhz/68030 do over 1mill bytes/second from Fast to Chip, in a real world situation like an anim? Here's an area where an A3000 *may* actually help. I understand that the A3000 Chip ram is actually 32bit ram as far as the 68030 is concerned (but accessed at 16bits for the custom chips). This would mean that the data the processor is moving (the Fast to Chip situation) would be moved in 32bit hunks, improving performance 2X? Hmmmm…. I might go down to my local dealer and give that a shot later today on their A3000. If so it would speak well for A3000 anim capabilities over the A2000/68030. –jp–seattle–
