Actually, no. Prime95 stresses higher than Orthos, a 12W higher max power draw, and better OS scheduling as well. The latest versions Prime95 automatically scales according to the number of cores. Orthos however uses old Prime95 algorithm that will not give accurate result on Core 2, especially quads.
