I can't seem to click on the link you provided. However Tom's Hardware says the 530 is a dual core. http://www.tomshardware.com/news/intel-dual-core-celeron-m,3495.html
I read Intel's site yesterday and they seem to address the celerons as dual core processors. Where am I getting confused? Thanks.
Edit: Sorry I cut and pasted your link and got to the site. I see what you are talking about. I guess my question is then, how can I maximize the performance of this cpu and why the conflicting TH new article? Thanks.
