Bulldozer Turbo CORE: This one goes to 11
John Fruehe, Director of Product Marketing for Server, Embedded and FireStream products at AMD, has published a new blog with details of how AMD's new Bulldozer architecture will leverage power monitoring technology to give significant boosts to core clock speeds:

AMD's PowerTune technology offers half of what AMD's new Turbo CORE technology will bring, monitoring the SIMD's and managing clock speed. Additionally, Turbo CORE will increase clock speed - over 500MHz for some cores and workloads.
All of this is based making Thermal Design Power and Actual Consumed Power come closer together. Where a system is designed to hit a specific TDP but never achieves that under actual use, the customer has overbudgeted for cooling and power. Across several computers in a lab, server room or steam cafe, that could be the difference between an additional two or three machines - or better add-in board graphics card.
What's interesting is that rather than capping TDP and pushing it down, AMD are moving ACP up into the TDP envelope they are already working in. As customers are already comfortable in that TDP position, they are in effect getting more performance for the same power - better perf/w.
However this won't necessarily stop AMD from pushing TDP down to meet ACP; in areas where performance is already adequate or indeed exceptional, less power can be used to provide that level - again increasing perf/w. In the long term, higher perf/w leads to better value, as the initial purchase cost is defrayed over time then the more significant running costs become.
For the end consumer, being able to run a cheaper, smaller case with cheaper, smaller fans and heatsinks inside could be all the benefit they want. Or, the money saved could be invested into a higher performing other component - graphics card, solid state disk, or more RAM; or more games and apps.
