I kinda saw it... But I mean sometimes you don't get the power of both displayed, you get 'Dual Core' and only the power of 1 core. Sometimes you don't. Sometimes you get 'Dual core' and the combined power. Sometimes you don't get 'Dual core' and the power of 1 core. It depends what diag program you use, DxDiag being the most common I guess, giving you the results you posted.
e.g. I have a simulation game which sees both of my cores and displays their combined power. Another game I have, a racing game, is an older one so only sips power from one core, and only sees that core.
