Yes because the 95W Kaveris are actualy 67W TDP, this is the reason there s not much difference with the 65W parts.
About this i did find it funny that the first reflex of some people was to assume that the 65W parts were of a higher TDP without even thinking that it could be the higher power part that had its official TDP greatly exagerated.
That does not make sense. If everyone is trying to get the best performance per watt, why would AMD deliberately exaggerate the TDP of Kaveri?
All chips that do not pass the 65W rating at projected frequencies are relegated as 95W parts even if failing the binning by only a few watts, the 95W moniker is convenient as it allow usage of existing 95W cooling solutions, this is what they have also done with their AM1 APUs.
The measured power drain CPU wise of a 7850K at stock is 54W with Fritzchess and 67W with Prime 95, the latter number is an absolute maximum as there s no heavy soft that manage to get Prime 95 power numbers, stressing both the CPU and GPU with Luxmark get you 55W, that s a long shot from the official TDP, these are measurements made by Hardware.fr on early retail SKUs, they selected the less performing one from the two they bought.
What is interesting is that they pointed that voltage was 12.6% higher than what was necessary for perfect stability and that lowering it by this number reduced TDP to 50W , 95W was reached at about 4.4GHz, these numbers are with Prime 95.

Excavator in 2011-2012 @ Sunnyvale teams put it on 20-nm LPM.
Excavator in 2012-2013 @ Boston teams put it on 28-nm SLP. (LP node shared with Samsung; SLP = LPP or ET-SOI = FD-SOI)((It is required to be shared with Samsung for AMD to use it))
~2012 -> Steamroller and Excavator was moved from Sunnyvale teams to Boston teams. So, Sunnyvale could design from scratch a new high performance x86 core. Like, they did in 2005/2006 to 2010 called Bulldozer.
That does not make sense. If everyone is trying to get the best performance per watt, why would AMD deliberately exaggerate the TDP of Kaveri?
Zen will be on the 10-nm(48-nm M1 pitch) node, K12 will be on the 14-nm(64-nm M1 Pitch) node. There is one more Excavator called Excavator+ which will be the 14-nm(64-nm M1 Pitch) x86.Do you mean the new AMD x86 uArch named Zen? So that will be on 20 nm, and not 14 nm as some have speculated?
AMD Zen is expected to arrive in 2016, so Samsung/GF 14 nm should be available by then.
Where did you get this information from? Doesn't seem accurate at all.Zen will be on the 10-nm(48-nm M1 pitch) node, K12 will be on the 14-nm(64-nm M1 Pitch) node. There is one more Excavator called Excavator+ which will be the 14-nm(64-nm M1 Pitch) x86.
Steamroller and Excavator -> Boston
Sunnyvale places full attention on -> K12 and Zen

Zen is coming out in 2016. The only fab anywhere near having 10nm ready for 2016 is Intel, and they ain't gonna fab for AMD. It isn't going to be 10nm.
Their 14/16nm wasnt ready this summer with core M being given a new stepping for that exact reason, i dont see how their 10nm would be ready in 18 months, unless you take Seronx s post at face value, of course.
be careful not to go down the rabbithole with his posts, just stay at the entrance.
GlobalFoundries will have 7nm ready in 2017.Anyway, the point is that GloFo, Samsung and TSMC just aren't going to have 10nm in 2016.
K12 is coming out in 2016, Zen is coming out 2016+.Zen is coming out in 2016.

You have the oddest fantasies mrmt.Yeah, and 3nm by 2018.
Mrmt, how many times do we have to tell you. FinFETs is what the industry has selected.It is a secret project developed by CEA-LETI, UTBETUBERSOI.
Nope. The scientific universe is safe till Planck's constant(length).Does the universe implode when we go past 1nm?
Nope. The scientific universe is safe till Planck's constant(length).
After 1nm, it becomes increasingly difficult to find what to use.

Also, the Carrizo Eng Sample_9874(15W)
CPU wise is equivalent to the FX-7500(19W/20W).
GPU wise is in between the FX-7600P(35W) and the A10-7850K(95W).
First h doesn't have a spacial only representation: http://en.wikipedia.org/wiki/Planck_constant
Secondly, quantum mechanical effects are already changing the structures and materials needed to create a reliable xtor. As far as I can tell, it seems most likely that quantum mechanical behavior will be the guiding principle in semicon design by the end of the decade (over classical E&M). Having to design xtors using QM rules with some sub nano-meter scale elements in an xtor is what becomes and stays hard.
Feynman said that there was plenty of room at the bottom. He didn't say it would be easy getting there. But this is going way OT.

No, everyone rather take a dump in your thread.That's cool guys, interesting conversation. hey why not open a new thread to discuss it?
