Netbook makers are starting to ship netbooks with new Intel Atom N455 and N475 processors that support DDR3 memory. They have the same clock speed and other features as earlier Intel Atom processors. The only difference is that they use DDR3 RAM instead of DDR2. But what does that mean in terms of actual performance?
Sascha from Netbook News.de managed to get his hands on a shiny new Acer Aspire One 533 netbook with an Atom N455 CPu and he pitted it in battle against a similar netbook with an Atom N450 chip. While the new model definitely had lower memory lataency and higher memory bandwidth, the difference wasn’t huge. And more importantly, Sascha says that you probably won’t notice much difference in terms of day to day usage — you’d probably need a faster CPU for that.
