29 Dec 2016 / Billions

When people are trying to sell candidates on their company, they like to throw around statistics like "we do billions of Xs per year", or if they want to pull out the really big guns, "we do one billion Xs per day".

I (and presumably everyone else) hear these statistics and think "wow a billion is a big number that's impressive" and don't think too much more about it.

Until now! Let's figure out just how impressive these numbers are. Assuming 365 * 24 * 60 * 60 seconds in a year, one billion Xs per year is 32 Xs per second, which is actually not impressive at all. If we try again with one billion per day (86400 seconds in a day) we get 11.5k per second, which is back into impressive territory... until you think about it.

My crappy game engine on my laptop with integrated graphics does 1M verts per second without the fans spinning up. AAA games routinely do 100x that - 4 orders of magnitude higher than 1b/day.

I should sell my engine by telling people it can do QUADRILLIONS of verts per year!!!!!!!!

If you have any comments email me and I will post the good ones.
