[citation][nom]DjEaZy[/nom]... is this chip x64 capable?[/citation]
The Atom processor is 64 bit capable,only you won't get any benefit with it, as the memory controller of the N550 only allows for a single channel of 2GB DDR memory at max.
[citation][nom]wotan31[/nom]What a pointless chip. The dual-core Atom 330 has been out since 2008. The 330 had a higher clock speed too. This "new" 550 is simply the 330 with a die-shrink, and a slower clock speed. So what? Old technology, no thanks. The reason Netbook vendors never used the 330, is that Microsoft didn't allow them to install Netbook or Tablet Edition of Windows on a dual-core processor. Microsoft demanded single-core only for the those editions, which means the OEM's would have had to use the much-more-expensive Home edition on a dual-core netbook. The whole situation is stupid.[/citation]
The N550 is a lot different than the N330, in that it has a graphics and memory controller onboard. The N330 needed a GMA chip.
And the reason why no netbook manufacturer used the N330 is because the N330 + GMA950 thermal envelope would be greater than a undervolted or ULV dualcore chip. Not only that, but the N330 was more expensive than the N280, and the performance was only marginally faster; not worth losing a couple of hours of battery life for.
So far, as performance goes, you probably will be able to overclock the N550 quite a bit from it's standard 1,5Ghz. The 100Mhz lower clock speed of the CPU does not significantly degrade performance for singlethreaded apps (at worst by 7%), but for multi threaded apps, you'll see a boost of about 180% or more.
Optimized multi threaded apps will see a near boost of 2x here!
And for those who completely dis the N550 you can always go for more expensive single core netbooks from AMD, only I prefer Intel over AMD in chipset anytime.
If only Intel would allow AMD and NVIDIA to create a good energy efficient graphics card. I think the integrated graphics chip is doing a lot of bad to the netbook.
A N550 is powerful enough to run simple games like PSU at resolutions of 1024x768 or 1024x600 if they only where equipped with a better than an intel graphics chip!
