Power or core gating means completely isolating one core so that it doesn't need to be powered. That feature is likely for turboCORE2.0 which 1) most people here don't care about (could matter to some though) and 2) ASRock doesn't mention in their slides. Not sure how you are craping on ASRock for that one.

it is very different turbo from sb which eats more power - crosses over TDP budget.
reasons why use AM3+ board : http://www.asrock.com/news/events/2011AM3+/
important slides : 2,3,4,5
like i expected, Dozer in old board can have : stability problems, low OC and performance, higher consumption , etc..
BDozer uses 3,2GHz HyperTransport
- that will minimalize communication bottlenecks .
explains why nvidia enables SLI on 900 chipsets
this features are enabled only on 900 chipset series
3,5MHz SVI_bus vs 0,4MHz may look like not important change, but that does mean 8,5x faster voltage regulation feedback.
This. Very good point. What people don't seem to understand is that "power saving" features mean more than just cool n quiet or some other feature that people always disable in the BIOS. Power savings internal to the processor is what the AM3 socket boards are going to be missing. This means BD is going to run hotter on AM3 which is going to cut into OC headroom. That should matter to people here, right? Furthermore, good current gen boards do have headroom and will run BD OK, but next-gen boards designed for BD will that much more headroom and will be able to provide things like current more stability (bigger pin holes). Again, something that may effect overclocking stability.
IMO, not only will TC2.0 be disabled on old boards (or AM3+ non-900 series boards) but traditional overclocking will also be limited due to chip thermals. Then when you add in all the little things like HT speed -- in the end you may get a pretty big deal.
