FUD Zilla had a meeting with ARM President Tudor Brown, the site says Brown sounded very enthusiastic about the ARM-based NVIDIA Tegra chipset. Brown also stated that he believes that the GPU maker doesn't need x86 to survive.
He said that ARM is very excited about Tegra, as he sees it as a great chip, and we do know that this is not the only product that Nvidia has in ARM's hands. Tudor believes that ARM chips in single and multi core designs are a great architecture that can run in devices Nvidia is targeting with Tegra.
The most expensive ARM chip would cost a vendor some $20 USD per chip, and this is a very rough number that comes after playing some serious money to get the license to use ARM's IP, while Intel’s x86 Atoms will sell for at least twice that money.
