TDP 45W means the whole class of chips does not exceed 45W. That's why all chips in this line are TDP 45W. If this chip actually consumed 45W, I wouldn't put the word "only" before it. Intel's 45nm E7200 is TDP 65W but consumes less power than the BE-2400.
The BE-2400 is simply an X2 4400+ tested to run at slightly lower voltage (-0.1v typical). It's not as big of a difference as people would like to imagine from looking at the TDP 45W vs. 65W. It is only ~1W difference at idle (NO difference if stock Cool 'N Quiet is enabled) and ~5W difference at load.
I've used a few of these BE-2x00 chips, and have liked them. Their main advantage is their better probability of undervolting/overclocking. If you're running it stock, anyone else undervolting an equivalent "regular" X2 chip could easily eradicate any energy efficiency advantage the BE-2x00 had to begin with.
