So let me get this straight. Because of the people who use the STEAM platform for gaming happen to have a majority of people use the HD 4000, intel should spend it's resources on developing faster integrated GPUs on their processors.
Steam has 54 MILLION active users.
I couldn't find how many people own CPUs with intel but I took the top 5 countries who would most likely have citizens who could all afford PCs (USA, Japan, Germany, France, UK) and got their population and took HALF of that to say how many users of intel cpus are out there today. Lets be real, it's probably a LOT more than that.
There were 651.51 million people are in those countries. Half of that is 325.755 million.
Intel has 13.26% of the GPU market on steam (Your "Biggest GPU is the Intel 4000 is wrong by the way, it's the HD 3000 so learn your facts
http://store.steampowered.com/hwsurvey/videocard/). 13.26% of the 54 million users on steampowered is 7.1604 million users have intel graphics as their main source of gaming.
We already established approximately 325.755 million users (CONSERVATIVELY) own and ran intel CPUs in the WORLD.
So 7.1604/325.755 gives us 2.2% of people who purchase intel CPUs use it for gaming. Yet, you want to tell me that it's a smart decision for intel to invest into improving it's integrated graphics for gaming rather than invest their things in the things the other 97.8% of people ACTUALLY care about.
Come on man use your head I know you come to the same conclusion I do. You don't cater to 2.2% of your market. You cater to the moms, dads, grand fathers, etc. who purchase your CPUs. Not the 2.2% of people running intel CPUs gaming on steam's platform. And that number is conservative, we know full well that a lot more than 600 million people have PCs, and we know a lot more than 50% of the market is intel based. If I used real numbers it wouldn't even be over 1%.
