News


Jan 19, 2012: In the past two months we published several stories, detailing Core i5-2450M, Core i3-2370M and B970 Sandy Bridge CPUs, spotted ahead of launch in specifications of Dell and Hewlett Packard notebooks. We also reported on a few mobile Celerons, that were going to replace older models, released in the middle of last year. Yesterday Intel added specifications of new processors to the ARK product database, and all CPUs now have status as launched in the first quarter 2012. The company also posted details on previously unheard-of Pentium 977.
