In a 8 bit plane amiga, thats under 3 Million pixels/sec. By todays standards, thats piss poor. Both the AMD and National chip set are pixel depth independent. The National is capable of over 60 Million pixels/sec. Although the AMD is not quite as fast, it has a reasonable price tag (~ $90 in plastic qnty 1000). > The TMS34020, TMS34082, and TMS44C251 are an awesome combination. > Imagine real-time VideoScape, imagine a killer flight simulator, 3-D > CAD in 3-D with real-time updates.

But if by Real Time you mean 30Hz update...dream on! A fully loaded top of the line Silicon Graphics workstation stuffed to the gills with HUGE custom ASICs is not capable of this. TI has merely improved what was a DOG of a graphics part with something that can somewhat compete with the other off-the-shelf offerings. I would love to see the '20 in an Amiga 3000, but I'm sure its probably cost prohibitive.
