Half speed compared to what?

If you're comparing to 16 bit modes, it's quite obvious: Going to 32 
bits with the same resolution means twice as much data to move around 
- and blitting to the screen (VRAM access with the CPU) is usually 
the major bottleneck, and takes the full impact of such changes.
