Some observers said that they doubt Intel would buy NVIDIA because it’s too expensive. The company has a stock market capitalization of about $10 billion, which means it would demand a far higher price than what AMD is paying for ATI.
Rumors have been around, but now they are starting to get serious. There’s no sense of even thinking “this will never happen”, because that’s exactly what most thought before AMD bought ATI. If Intel bought NVIDIA, that would bring an extreme twist to the CPU and GPU market.
