Even then it's fast enough for games.
It *is* a full implementation of bitblit with extensions. It doesn't have line draw or area fill but it does have smudge (an indirect addressing mode) which can be used for fast magnification or hflipping rasters. It's also capable of blitting across the 24 bit address range. IE you can blit from ROM or hit the memory mapped IO registers with it.
Compared to the 68k it's no contest. It'll murder it for speed since shifts are free. The sound on the ste on the other hand... Grrrr...
The Mega STE (not Mega ST) did have a 16mhz option yes but as the ROM required for it is so new most original games don't work.
The Blitter/Stereo DAC/4096 CLUT mods are fine as they are but two points...
1. ALL software still looked the same with zero improvement on the STE machines with the extra features.
2. If you thought the AGA catalogue was pathetic compared to OCS/ECS then you just check out all 5 STE only games ever written for the Atari.
Spec sheets are fine but as a user when no games are STE specifically designed and all your old games still shift along like a granny with two broken hips despite you having a good DAC/Blitter added onto the £100 extra machine you see where the problem is...........??
