Nvidia Rumored to Compete in Supposedly Uncompetitive Market

Rumors abound that graphics chip maker Nvidia is getting set to enter the x86 processor market. Recall that, according to AMD’s lawyers, the processor market is uncompetitive and being unfairly monopolized by Intel.

Now, if the antitrust lawyers are correct, and the CPU market is uncompetitive and needs government intervention, then there must be some barriers to entry that are keeping other competitors out of the market, allowing Intel to reap outrageous profits. However, if Nvidia can and does enter the processor market and supply an alternative processor product line, where would that leave the antitrust argument?
