I have a CR-48 which runs the N455, and a custom built nettop running Windows 7 Home Premium 64 bit and a D525 @ 1.8ghz. According to this benchmark site (PassMark - CPU Benchmarks - List of Benchmarked CPUs) the D525 has more than twice the power of the N455. Yet, in realtime usage, I find them to be rather similar in performance given the differing platforms. Both feel choppy and laggy at times, especially when there is a lot going on. Neither can play 1080 video to any acceptable degree and both struggle to play 720.
