390X or 980ti - which one are you going for?

I'm a fan of AMD and their approach to GPU-design etc and that cooler was without doubt adequate at *best*

ie Crap :D

Thankfully they started to fix the issue with the 295x2, even you can't deny that Greg ;) Even nVidia stood still with the Titan Z (which is a damn shame, imagine the potential with an even better AiO sys!!)

Just need them to carry it on now with the next gen

Yes that's why it was made to cope with 94c instead of 74c because the arc is not efficient enough to give the same performance at 74c on the reference cooler, so over all performance level is greater than if it was constrained at 74c on the reference cooler, its not more efficient at 94c no claim has been made that it is, it gives more performance at 94c on the reference cooler which is the point because it can cope with more watts than if it was constrained at 74c.

On any given are Arc as performance goes up efficiency goes down, that's a given but that was not the point, but over all performance is not mutually exclusive to efficiency, you can get more performance at the expense of efficiency which is the point to why the chip has not been constrained to 74c.

You clearly did say that 94C is more efficient than 74C but I am not going to say it again and again,

just seen the big edit and he could have just said "Sorry, I was wrong".... Oh well, no loss.

No i did not, i said more performance at 94c than at 74c so what is clear is you reading it wrong.

And the context was set before hand with the article, the word watts was used and also by me beforehand at http://forums.overclockers.co.uk/showpost.php?p=27499989&postcount=164 so you should have been able to follow the context even without me constantly mentioning them and 94C or 74C dont get generated by themselves, it takes volts which also equals amps and watts which is a given but my bad it seem you need your hand held every step of the way.

As i said before and i was right, you are so far from understanding the point its not even funny.

I can see why DM needs to type walls of very details text because he can't afford to leave anything out or some people get lost fast.

there is an efficiency at work, here. the ability to remove heat from the gpu increases with higher running temps. so, the efficiency of the cooling increases....

but that probably has a minimal effect on performance per watt in the grand scheme of things and it isnt something people should be hanging off. the point of running hotter was to extract more performance - they did that, at the cost of more power being used.
 
Letting the card run at 94c allows the reference cooler fan to run quieter than if the card was running 10c cooler, this is what it boils down to. (says the man with 9 reference 290X/P cards) :)
 
This might be of interest to this thread, we might not know nothing about no new Discrete GPU, but what AMD might be doing in that regard can come from other platforms, they don't just do Discrete Graphics.

New Carrizo benchmarks were spotted on the SiSoft Sandra database showcasing graphics performance that’s ahead of AMD’s Kaveri and Intel’s HD5200 Iris Pro by an unbelievable margin. The A10 7850K scores around 270 Mpix/s while Intel’s HD5200 Iris Pro scores a more modest 200 Mpix/s. Carriso scores here over 600 Mpix/s which suggests that Carrizo is more than twice as fast as Kaveri and three times faster than Iris Pro.
To put this into perspective this is what an R7 265 graphics card scores, a card that offers the same graphics performance inside the Playstation 4.

Kaveri is GCN 1.1, (HD 7790/R7 260X) The performance is equivalent to just less than a GDDR3 7750.

Carriso is a 35 Watt 4 Core Chip with its iGPU

Wow that's amazing if they actually got the chip to run at 35 watts! I just can't believe it though because for one its AMD lol they always have high power ratings on both GPU and CPUs lol. But two if its integrated gpu actually has twice the performance at that power consumption thats just insane for a APU! Does that means things look more promising for discrete GPU too?

Agreed for single card systems but not ideal for Crossfire/SLi users but then again, they should be going water cooled anyway, so fair point in total :D

the problem AMD have is that Nvidia's next monster card will probably be colder than theirs..but removing the heat from a 300W card is far easier than that 7990 disaster i had, so who knows, so if a 94 degree card can be reduced to say 84 degrees, then it'll still be of interest to me...

all of this is totally irrelevant because what i'm after next time is the biggest mother ***** single card that i can get my hands on, my guess is the 390X wont be powerful enough to justify selling my SLI 970s !!!!!!!!!!
