Atari made a point of doing "everything the Amiga could do". It was mainly because Jack Tramiel of Atari held a grudge against his former company (Commodore).
But the Atari computers didn't have the graphics co-processors or heavyweight DMA capabilities that the Amiga did. So they did what the Amiga did, but they had to make the CPU do all the work instead of being able to dump bit-blits and the like off onto the secondary processors.
The C64 and TI computers had hardware sprites, but not full bit-blit, and I don't think that either of them had the ability to do the framebuffer-hopping that allowed you to smoothly pull one display down over another while animation was in full swing.
We really didn't see that outside the Amiga until PCI bus graphics cards started loading up on processors. And even then, I saw pictures "tear" when they scrolled for years.
