ARS Technica has another article about AMD's acquisition of ATI and takes a look at how this affects NVIDIA. They write NVIDIA still supplies about half of AMD's chipsets.
Now that the $5.4 billion ATI-AMD merger deal has been completed, eyes turn towards the future. AMD today already announced plans for a new "Fusion" project aimed at integrating graphics and x86 CPU functions on a single piece of silicon. Is NVIDIA, or Intel for that matter, scared?
NVIDIA has had a mostly positive business relationship with AMD for over 10 years—a relationship that includes the beginnings of the quite successful nForce chipset deal that gave AMD a motherboard chipset that could be respected. Many years later, the graphics guru still supplies nearly half of the chipsets used by AMD, and will continue to do so for the foreseeable future.
