I won't even bother. If you think that making a chip that is on par with something 9 months old is an accomplishment then it's useless to continue this discussion.
It is actually quite the achievement when that chip has been the reigning champ for 9 months.
Selling the best priced hardware (by a large margin) 7 months after it first tested is a testament to how well AM's chip is designed.
They sell because they are low price...not because they are great chips. AM sells for the cheapest so people buy. I assume there margins are not great at the prices they sell for. Didn't FriedCat say AM was negative cash wise?
