There are two new "P" processors in the lineup - the i5-2450P (quad-core, 3.2 GHz) and the i5-2380P (quad-core, 3.1 GHz). It is already challenging for the average PC buyer to read and interpret Intel's model numbers. The "P" has, of course, a cryptic meaning: These Sandy Bridges do not have a (functional) graphics core. Compared to their counterparts with graphics support, the P processors are slightly cheaper: The i5-2380P sells for $177, which is $7 less than the i5-2400 (quad-core, 3.1 GHz). The i5-2450P lists for $195, $10 less than the i5-2500 (quad-core, 3.3 GHz).
Also included in the refresh are the Celeron M B815 (dual-core, 1.6 GHz, $86) and B720 (single-core, 1.7 GHz, $70) as well as the Celeron M ULV 867 (dual-core, 1.3 GHz, $134) and 797 (single-core, 1.4 GHz, $107).
