If TDP were simply a measurement of power consumption, it wouldn't have the word "thermal" in it.  TDP is a value that describes heat offset.  Processor companies rate worst-case-scenario heat offset by TDP.  That doesn't mean TDP does not give you at least an idea of chip power consumption, as motherboard manufacturers use rated TDP values to determine processor support as per supply capacity of the VRM setup.


Nevertheless, I had a case in point back then; I'm pretty comfortable with the results of the upcoming final chips - but why at the time, a processor on a new, smaller process node that was supposed to bring power consumption improvements and lowered heat was rated at 95W TDP for a DUAL CORE ES at a low 1.8Ghz and distributed with such heat offset requirements makes absolutely no sense.  It's the kind of thing that would definitely give you a bad outlook on the final product regardless of which brand put out the processor.  I fail to see how that nor this has anything to do with, as you so claim, brand loyalty.  Your feeble attempt to start a conflict here is quite astonishing!  Is this because you have a problem with me, perhaps?

Just read somewhere else that amd piledriver is using resonant clock mesh which gives an estimated 24% savings in power. Would post link but i think its against the rules. This along with an estimated 10% improvement on IPC gives me hope that amd might be able to claw back especially with trinity in the mobile sector.

up to 24%*
meaning at certain circumstances they will achieve a maximum of 24%, thats real good news for mobile market especially ULV(bulldozer does great on power at low frequencies, and with this it will do even better) so if we assume 1.5 ghz is the sweet spot were that 24% kicks in then u basicaly get 2.0 ghz with the same power usage
but when you start going up to higher frequencies though using this technology would probably yield about 10% more peak frequency at a given power envelope or maybe less, which isnt bad especially considering this is only an IP added to piledriver and that 10% is seperate from the enhancement within the modules and latencies and what not

im saying this out of speculation and i could be wrong, because i heard something about this technology being set to either work for better efficiency or higher frequencies
post #84 of 86
be curious to see how a larger l1 and wider decoder handle the throughput problem bulldozer seemed to have with front bottle necking. piledrive might gain more then 10% ipc, in benchmarks where the l1 and decoded got bottle necked.

Ive now read more up on this and we can expect a 5 to 10 % increase in power efficiency in piledriver because of the cylos tech.

I personally can't wait for Trinity.
