It doesn't have 3D, but what it does have is 8 and 16bit chunky graphics modes, which make doing software renderers a lot easier than the planer modes of the old chipsets. With chunky graphics, you can write out an entire pixel with a single write, which is essential for rasterisation in software 3d games. It's not like PCs got 3d graphics cards until late-95, the AAA chipsets released in 1993 might have allowed the Amega to hold on until 96, get proper Doom clones (and maybe even quake clones) and then get it's own 3d accelerators.
