Aside from ignoring the Game boy color, you are comparing 2 very different points in the indutry's lifespan.
The gameboy and snes existed in a time where they were following the industry's growth out of the not-so-long-ago crash. Basically, the gameboy and the snes had a much harder time selling because the industry itself was a lot smaller than it is now. They were the leaders of both respective sectors with a huge market share on the industry.
Now however, the industry has grown significantly, allowing for consoles to reach higher numbers easier.
comparing sales of 30 years ago is not a good metric of performance since the industry has greatly shifted since then
