I believe the reason why no Intel 4000 graphics, is because there are no Intel CPUs in the price bracket they were looking at.
They were trying to have an even playing field (around $120).
That is a fair enough argument. I don't see a problem with sticking to a price range.
That brings up a new issue though; For less
than $120, you could get:
Yes, in heavily-threaded stuff, the AMD's "four" threads will beat the Intel's two, but at the super-budget end desktop Trinity is aimed at, the G620 is plenty fast enough for what casual users need - they don't tend to multitask VM's and compile things all day, because that is what the $300 chips are for.
In gaming (especially at the 1080p resolution most people will be running a television or cheap 23" monitor at) the HD6670 on GDDR5 will tear the Trinity's IGP to pieces and then defacate on the remains.
It's not even a remotely fair contest.
