In short, AMD's Brazos platform and their Zacate processor consume significantly less power than a dual core Atom/Ion2 solution at idle and under load. In addition, at idle, Zacate even consumes a lot less power than a standard single core Atom design.
In notebooks and netbooks this equates to one thing; extended battery life. We'd also offer that again, the power consumption measurements here are very conservative, comparatively for Zacate. The reference board we tested definitely wasn't optimized for power consumption. Without a doubt, Brazo and AMD's Zacate E-350 processor offer excellent performance-per-watt efficiencies that will likely have Intel on its toes in a big way moving forward.
