I don't know how the Virtual Boy's 20 MHz NEC V810 CPU compares to GBA's 16.7 MHz ARM7 CPU. obviously they must be different architectures and cannot be compared on MHz alone.
the DS has something like a 67 MHz ARM9 CPU plus the GBA CPU.
I can tell you one thing though, the Virtual Boy, GBA and DS CPUs most likely all pale in comparison to the CPU that was supposed to be going into Nintendo's Project Atlantis color handheld. Atlantis was to have a StrongARM CPU running at 160 MHz. go through your Next Generation magazines from 1996-1997. or search Google Groups for 'Nintendo Atlantis 160 Mhz' and 'Nintendo Atlantis 160Mhz'.
I speculate that Atlantis was wittled down into the GBA.
I remember the stuff about Project Atlantis, but I'm not convinced the original was going to be a lot more powerful than GBA. I think some of that was sensationalist reporting.

ok, perhaps that is true. but still, Atlantis was probably going to be at least faster CPU-wise than GBA. it's entirely plausible based on Nintendo's history. i.e. Super Famicom was going to have a 10 MHz 68000.
Neat for all of five minutes, when you realize that everything done with Virtual Boy could've been done on any system and without migraines.
That's interesting that they were about the same as far as the MIPS rating was concerned.
From what I can gather, the Virtual Boy could do four shades of red (similar to how the original Game Boy could do four three shades of black and the background green/yellow color), but I swear that emulating these games, there look like there are more colors than that.
I think the GBA's ARM7 packs in the 2D Hardware accellerating unit (tiled backgrounds and sprites) but for non graphical performance those CPUs are prtty much equal.
