*sigh* power consumption isn't the same thing as efficiency, and TDP isn't the same thing as the actual power consumption. Although processors almost always become less efficient at higher clock speeds, if you don't like the extra power draw, just lower the clock speeds. The supposed 15% IPC is still substantial. AMD might have the better product but they still have a long way to go to beat Intel. In the perspective of business, AMD is catching up, but they're not winning. Regardless, I do believe the 5000 series will be more expensive.
