The Intel Atom microprocessor was officially launched on the first day of Computex 2008. NVIDIA had sought to dampen the Intel Atom launch by launching their competing Tegra system-on-a-chip a day earlier, but from what we could tell, Intel was totally unfazed. In fact, they did not even mention Tegra during the event. It was as if the Tegra wasn't even worth talking about...
We had earlier covered the Intel Atom in our Intel Atom Tech Report, so it is really no secret what the Intel Atom can do. Based on a new microarchitecture, the Intel Atom was designed for use in the ultra-mobile, low-cost market that is the domain of netbooks and nettops.
Basically, these are small and light notebooks that can be made cheaply. Hence, the requirement for a small, low-cost processor that offers better price-performance-power ratios that are possible with current notebook processors. Read on and find out.
