Intel has yesterday updated its processor offer, adding no less than six new models, all Celerons and all targeting mobile devices. This fresh batch is of ultra-low voltage variety and it includes two chips based on the Haswell architecture, the Celeron 2981U and 2957U, and four on the Silvermont architecture (and part of the Bay Trail-M line-up), the Celeron N2920, N2820, N2815 and N2806.Frequency-wise, the processors go from 1.40 GHz to 2.13 GHz, but they don't really vary in terms of pricing as five of them cost $132, while only the Celeron 2981U goes for $137.
