[TWEAKERS]Nvidia's GTX 590 seems to be facing serious problems - Page 7

post #61 of 70
the problem is nvidia's power throttle system is based on software, but amd's is based on hardware.

Well, Nvidia said that a new driver will fix the problem. So the power throttle system must be software based.

AMD PowerTune Technology Whitepaper, page 9:

AMD PowerTune power monitoring and management technology is integrated into the GPU silicon itself to essentially eliminate the unpredictable variability that would arise if it were implemented at the board or system level with analog sensors and feedback mechanisms. Activity is monitored in to infer real time power draw at the device level through integrated counters that are placed throughout the GPU. As a result, AMD PowerTune is transparent in its ability to contain applications in real time without a reliance on specific drivers or application profiles. AMD PowerTune technology is also programmable in a way that can allow GPU and system designers to tailor the power containment behaviour to the specific needs of the user. This can allow some systems to set a lower TDP threshold to enable a cooler overall system under heavy load, or set a higher TDP threshold in the case where there is known to be additional TDP headroom.

A much less desirable approach would be to contain GPU power through application profiles and application detection. This creates a dependence on driver software that simply cannot take into account all applications that can use GPU compute and rendering resources. Driver based application profiles can also become outdated very quickly and result in severe performance degradation. AMD PowerTune technology‟s hardware based digital monitoring solution contained within the GPU silicon avoids these pitfalls.


I recommend reading through the whole whitepaper, not very long, not technical and explains some ideas around TDP very well.

Bottom line:

AMD is almost 2 generations ahead of nVidia when it comes to controling power draw of the GPU.

These cards are meant to be sold at low volume, so making $10 (I just made that number up) per card on a low volume car like this shouldn't effect their profits too much.

yeah, it's almost like nvidia relied too much on its driver team. they have good drivers, but this overconfidence is biting them hard.

With all the problems, I wonder if Nvidia will release a GTX 590 V2. I know there may be some non-reference cards with better components or whatever, but is there any chance Nvidia will actually redesign or even try to fix some things about it?

Heres how i see it... Nvidia has the Fastest Single GPU and AMD has better design when it comes to creating a Dual GPUs Cards.

Nvidia did have a great design in theory but however went cheap on the VRM. I don't believe the driver has anything to do with the OCP IMO (Correct me if im wrong, if you have proof from nvidia or creditable source that is relate on the driver, Dont care about AMD powertune thing). I think its built inside the card bios itself.

Time can only tell, Maybe another company will recreate the 590 with better VRM. Both company's have there strength and weakness. I personally will never go back to AMD they only support 3 generations with there drivers at a time from what i can tell. Also dont like there Warranty methods, got burn bad once 6 years ago. I will however recommend to people to there GPUs when there looking for something in there price range but will warn them of there drivers.

What im trying to say is we all defend our own Product for which we buy. No need to bashing each other. Where all here for a reason. To discuss are hobbies and to get the most out of our products.

If it wasn't for this competition we being paying alot for our GPUs from one company. For This generation of cards from each company comes out to be a tie as i see it.

AMD and Nvidia my hats off to you

just buy a non refference msi lighting or whatever gtx590 instead ... your sure it will be safe to oc and enjoy for a while ...
