AMD's deal has always been to compete on price. They make processors that are typically below the beginning prices for Intel's new processors. I see laptops at the lower price ranges using AMD processors, more expensive laptops typically use Intel processors. The same thing probably applies to desktops, and certainly in the gaming world depending on budget.
If AMD wants more market share, they need faster processors to challenge Intel's new products. If Intel wants more market share, they need to bring out lower priced processors to challenge AMD's products.
I would rather see AMD gain a little market share, to put more competitive pressure on Intel. If AMD fades away then where will we be?
