I just shelled out for a Gigabyte Radeon R9 290X and an Accelero Xtreme III. Should I be concerned about this issue severely hampering the performance of my new R9 290X?
You shouldn't be affected at all.

Yeah, AMD has such an advanced turbo mode, that you lose up to 20% due to throttling :awe:
NVidia GPU boost 2.0 is so superior, it's not even funny.
......
Therefore it seems odd that for 780 Ti review the analysis portion regarding 290X comparison only covered Quiet mode only.
Additionally in the conclusion of 780 Ti review :
quote "...GTX 780 Ti still has other advantages power and noise in particular..."
This seems to suggest the conclusion was based on comparison between 290X Uber mode vs 780 Ti instead of the 290X Quiet mode - since from what I can observe within the provided data, the power and noise levels between 290X Quiet mode vs 780 Ti were not "particular" enough to warrant such notable advantage toward 780 Ti.
This seems relevant enough to note since if one were to strictly keep the analysis focused on the "default" (quiet) mode for 290X, it should apply also to power and temp conclusion as well as any performance analysis.
.......
AMD's new turbo is obviously more advanced to any technically competent observer in terms of using as much available headroom as possible. Whether or not it's being used and marketed in a way that benefits the consumer is of course hotly contested. Before the 290X launch AMD made a fuss about deterministic vs. non-deterministic boost, and although their stance was completely PR driven they had some valid points. At the very least, AMD deserves to be called out for the hypocrisy of it all.
The 780 Ti runs cooler because of the better cooler not because it consumes significantly less power.
In fact a 290X with a better cooler will consume less power than the reference 290X.
So I've got some thoughts here, and perhaps we'll turn these into a post on the main site but I wanted to get in this thread as you guys are honestly the source/inspiration for any such post.
Let's start with why we want to define a clear framework for how general performance/power/sound testing goes. Not only does it allow for fair comparisons between products, it also helps us deal with the inevitable situation where a manufacturer submits a ringer for review (e.g. factory overclocked card). I don't think there's much argument against this point - we all want a level playing field.
Similarly, it should be obvious why we'd want to include in such a framework the idea of testing a card at default settings. Having a strict policy there prevents a situation where AMD/Intel/NVIDIA show up and say hey we're selling the card in configuration x because of yields/experience/someothervalidreason, but it's really quite awesome and can run in configuration x+50% and that's how you should test it and btw we rule the world if you test it like that. This makes a lot of sense particularly when talking about encouraging factory overclocked comparisons.
The close relationship between fan speed and performance sort of throws a wrench in all of this. When Intel first started introducing aggressive turbo modes back in Lynnfield I was worried that it would completely corrupt our ability to reliably test CPUs. It turns out that wasn't the case. With graphics however the situation is a bit different, and with the 290/290X we're beginning to get a feel for exactly why that is.
I originally assumed the reason this was a problem now (and is going to be in the future) is because we're stuck on 28nm trying to get more performance without a good process tech solution until 14/16nm FinFET in 2015. Now I'm feeling like this is just going to be a part of the reality going forward, so we need a real solution.
AMD's Uber mode in my eyes isn't the same as a factory overclocked card. At the same time, it's not the same as what we've done in the past - which is test a totally stock configuration (reference clocks and fan speed). I personally believe in the whole living document philosophy when it comes to things like constitutions or review policies, but here's where we can get into trouble. In the case of the 290X, AMD has two modes and you can make a good argument for why you should test both. Let's now take it one step further: what happens if NVIDIA shows up next round with 3 modes? Do we test all 3? Which modes do we then compare against AMD modes, particularly if they only line up along one vector (e.g. performance or acoustics, not both). What if AMD responds the next round with 4 modes, etc... It can quickly get out of hand.
What I'd like to do here is define a good policy for what to do if this turns into a fan speed arms race. Dealing with the 290X is simple: Ryan tested both quiet and uber modes, and I can totally appreciate the argument for including analysis based on both. What Ryan is concerned about is the future. This isn't a matter of him being lazy (me being the person he reports to, I can tell you that's definitely not the case - he's kept up an insane work schedule over these past several weeks in order to get everything done as best as possible. The launches aren't done yet for the year, add in short NDA windows, issues with cards/drivers and of course any travel and the pace you have to keep in order to put out these reviews is insane). The precedent we set here today will directly impact what manufacturers attempt to do with their reviews programs in the future. The safe bet is to stick with testing in default configurations. I am (and assuming Ryan is too) more than willing to expand/change/redefine that, but the question is how? Let's look beyond the present 290X situation and think about what happens next. If acoustics and performance become even more tightly coupled in future GPU designs, and multiple optimization points exist for each card (with 1 default setting obviously) how should we deal with that going forward? If things get crazy, we could be in a situation where there would even have to be a tradeoff in terms of review depth vs. card configuration combinations. E.g. would you be willing to give up a resolution setting across all games tested in order to get another operating mode included? What does this do to the complexity of graphs?
I don't know that I've got the answer/a solution here, but this is the discussion I'd love to have.
As I mentioned earlier, this is a discussion that we might take to the main site at some point. We felt like we owed it to you guys to start it here given the time/effort you guys have put into it already. We're here to listen and will obviously take your input into account (e.g. the 290 fan noise update was a direct result of your feedback). All that I'd ask is please be respectful of Ryan in your discussions of his work. He really puts a ton of time and effort into this stuff and takes all of your feedback very seriously. Obviously you're free to post/say whatever (as long as it doesn't violate our ToS), but I've always been a fan of the golden rule 🙂
Thank you all for reading the site and for caring enough to engage in hundreds of comments on the forums and on the site itself. I'm off to bed for now but I'll check back tomorrow.
Take care,
Anand
How about you raise the fan speed on the 780 Ti so that it gets maximum boost clock speed at all times with no down clocking?
That's basically what "uber mode" is on the 290x..
Why don't you stick to the question at hand? :thumbsdown:
What are the standards that a review should be conducted with? It's not an AMD vs. NV question, it's a flat review policy.
Lol? The 290 boosts 43% with a crappy reference cooler while the 780 Ti boosts 17% with the Titan reference cooler.
I'm sorry, but anyone suggesting that the throttling situation on these cards is anywhere near similar is basically lying through their teeth. Kepler has variance, but it isn't 20% variance. This makes it ALL THE MORE CLEAR why AMD not improving their shroud design was an utter design failure - their GPU with powertune clearly ties cooling versatality with performance, therefore it REQUIRES good cooling/acoustics to operate effectively. Having to compromise between noise and throttling by 300mhz is pure garbage. Period. You people as consumers should demand better than this, instead of believing that AMD can do no wrong.
I doubt anyone here believes that AMD can "do no wrong".
Your 78 posts so far complaining about the cooler are however far harder to tolerate than if I had the damn thing to my ear.
Uber mode and GPU boost 2.0 are in no way comparable, anyone suggestion otherwise is simply to obfuscate the facts - GPU Boost 2.0 does not throttle more than 1-2 bins after 4-5 hours of "warmed up" use in my experience, while here we're seeing the 290X throttle by 300mhz.
Summary:
1)GPU boost usually never throttles, but if it does, will be 1-2 bins (13-26 mhz)
2)AMD's powertune throttles by 300 freaking mhz during quiet mode, and consisntelty does this.
3)GPU boost 2.0 is a guaranteed speed with every Kepler boosting well PAST the guaranteed speed out of box.
4)AMD powertune boost is a "holy grail" speed that will only be hit if you use an unnecessarily high fan speed.

95c, of which it manages to consistently approach.
See my reply to HurleyBird. The 290 has a higher percentage gain from boost, but look how high it's thermal threshold is?
95c, of which it manages to consistently approach.
In light of that, the reference cooler doesn't look so crappy now does it, as it's having to deal with a lot more heat than the Titan cooler..
With such a high temperature threshold which is a result of the higher TDP, I'm actually skeptical that the AIB coolers will be capable of fully mitigating the heat problem.
The 290 series was designed for higher temperatures and it has a higher TDP, so we shouldn't be shocked that it comes with a noisier cooler.

The 290 cooler under the hood is exactly the same as the 5870, 6970, and 7970 coolers.
The 290 cooler under the hood is exactly the same as the 5870

The 290 cooler under the hood is exactly the same as the 5870, 6970, and 7970 coolers. Therefore the acoustic performance is directly related to using a 4 year design, and nothing but that - keep in mind that during actual gaming (non furmark) loads, that the Titan uses maybe 8-9 watts less than the 290X in uber mode. AMD could have easily made a better shroud to eliminate the need for a noise versus throttling quiet mode compromise, but they didn't. It's obvious as to why to anyone that has had experience with AMD Shrouds from the past 4 years. They never changed the under the hood design of the reference shroud for the past 4 years.
Further anecdotal evidence from those using accelero coolers and what not with the 290 are also showing shocking temperature drops of 40-50 degrees. The issue isn't the chip, per se - like I said, the Titan and 290 don't consume much differently in terms of power draw. Yet the Titan shroud is just superior in terms of acoustical performance, while the 4 year old cheap plastic design of the AMD shroud is beginning to show its age. This could have been completely prevented by AMD with a better shroud. The temperature differences that people are getting with 3rd party air coolers is precisely evidence of that, when a gelid or accelero cooler lowers temps by 40C, it makes it all the more obvious that AMD screwed the hell up in their design.
I should make it clear that noise isn't the big problem. The big problem is shedding 20% performance for any quiet fan profile. Again, that is pure freaking nonsense and consumers should not put up with that. ESPECIALLY when that is the default mode on the 290X.
How about you raise the fan speed on the 780 Ti so that it gets maximum boost clock speed at all times with no down clocking?

How about my standard as a consumer? You and I both know that the typical reader for GPU reviews look at FPS charts and nothing but. Seeing uber mode numbers without knowing the context behind it will lead folks to buy a GPU and not understanding that they lose 20-25% performance for using a quiet mode fan profile. This is nonsense for a product to have such a deficiency. NONSENSE. You guys need to stop defending AMD on this crap and demand a better product. This BIOS switch SHOULD NOT EXIST. It should have a shroud that doesn't necessitate a noise versus throttling compromise. Period.
If AMD wants the 290X to be benchmarked in uber mode by every review website, they should make 55% fan the default speed with no quiet mode option. OR, they should put a label on their cards warning consumers that they lose 20-25% performance by using any sort of quiet mode - that's what really annoys me about this shroud. Noise is part of it, but with the prior generation ATI Cards you could easily fix this with custom fan profiles. With the 290X? Sorry you're screwed, you want a quiet card - you lose 20% performance.
In fairness that would probably do nothing because the 780ti would throttle from its power limit no matter how much you let the fan spin up. As the card comes stock, unless you run it in a sealed box with no air flow, it will wind up running as fast as it possibly can.
"They both throttle". Yeah okay if you say so. One throttles by nearly 300mhz and another barely throttles even with vsync off at 100% GPU load -I've used kepler cards for quite a while now and the throttling is far less of an issue and does not cause a 20% drop in performance. In my personal use, none of my kepler cards have ever throttled more than 2 bins (26mhz) in real world gaming, and that is after 4-5 hours of warmed up use.
Meanwhile, you have the 290X with 40% fan speed throttling by 300mhz. Kepler's boost has variances but it is so minutely small it isn't worth noting, and it doesn't cause more than a 1-2% performance drain at MOST. Furthermore, the boost speed avertised isn't a "holy grail" type of speed, all kepler cards boost WELL PAST the advertised speed listed on the box. For example, the GTX 780 advertises a 914mhz boost, nearly every person i've spoken to boosts past 980 easily. Further, my SC ACX 780 advertises 1020mhz, and it boosts around 1100 out of box without overclocking, and all Kepler GPUs are similar.
The differences with AMD's powertune are:
1) throttling by 200-300mhz as opposed to Kepler's meager throttling of 1-2 bins in the worst scenarios.
2) the boost is an "up to" speed while Kepler's boost is guaranteed and all Kepler GPU cards boost WELL PAST their advertised speed out of box, without overclocking.
You can say both cards have the potential to throttle, but I guarantee one of these cards don't throttle to lose 20% performance. And that ISNT the 290. This is the single reason that AMD's decision to use that cheap shroud is so disappointing - I don't know of any GPU that had this type of variance for low fan RPMs. I know the 5870, 6970, and 7970 sure didn't and I quite liked all of those cards - all of those GPUs could be used at reasonably quiet levels WITHOUT sacrificing performance.
So they are actually giving the 780ti the benefit of the doubt that they will offer custom cooling solutions that will stop throttling and adjusting the 780ti to compensate for it's reference cooler's throttling. They are actually being quite kind to do this because stock out of box the 780ti doesn't produce these numbers. It produces the slower results.Hardware.fr said:As with our previous tests, we ensure to test different solutions taking into account their system power management / frequency / temperature so as to provide you with interesting and relevant results. Our approach at this level is of course not rigid and we adapt according to the product tested.
So this time we have not tested the GeForce GTX reference with two additional fans as was the case during their tests. Instead we have for cons incorporated the results of GeForce GTX 780 and GTX 780 Ti which we call Uber. These GeForce GTX "Uber" match cards able to maintain their maximum frequency (almost) continuously as would the case with a kit watercooling, raising the limits of GPU Boost or as this is exactly the case with many partners models for the 780 GTX, which then benefits from a system more efficient axial cooling. Everything suggests that the latter is also true for the GTX 780 Ti. Present the performance of such models seems to be a better compromise than adding additional cooling in this case, especially as the Radeon R9 290X Uber also ensures to maintain its maximum frequency.
Finally, note that due to the influence of temperature on the results, and the fact that we measure performance on a table benches taking the time to let the temperature / frequency of different cards to stabilize the temperature of the room was controlled and set at 26 ° C for all tests.
i have to say your ranting is louder and more obnoxious than the R9 290 cards fan noise. :whiste:
