dont buy used cars and you will be fine :biggrin:

voltage is high but there are heaps of people on air around 1.3 volts on AMD cards

Yeah, I'm not reading the entire thread, but what caught my eye was the double precision was cut to 1/8 on the 290X. Notice how it's slower than the 280X and even the 780 on the benchmarks. Obviously that's not really important in games, but I thought it was interesting.

I'm looking specifically at 1.4v and the performance of the stock cooler at 1.4v and 1200MHz.

I wasn't looking at the card snapper cooler.

I have used car salesmen phobia. :|

Have you seen the video of the stock cooler at 100%? It seems to be pretty good at moving air...
And incredibly noisy.

Interesting that no one really brought this up, wonder if that's artificial or baked into the design. No Firepro version of Hawaii?

Presumably this is how they got the performance density they did out of the card. By stripping back the double float performance they reduced the size of the die making it a great gaming card (similar to how the 680 is stripped back in a similar way to focus on gaming) but poor on compute. That might also explain the heat of the chip, they aren't spreading the heat out over as large an area and the stream processors are getting higher utilisation as the hardware for the double floats isn't sitting idle in the game.

Interesting choice on AMDs part.

Wasn't there something like nv using dedicated units and amd SP for DP? Nv needs more die for dedicated DP, but those are less powerhungry when not used. AMDs aproach doesn't require much die space, but increases power consumption.

I would say it's quite a bit of exaggeration:
http://anandtech.com/show/7457/the-radeon-r9-290x-review/18

AMD is interested in GPU professional market and I'm sure that they want more of it with Hawaii release.

After years of neglect, AMD’s [graphics] workstation group, under the tutorage of Matt Skyner, has the backing and commitment of top management and AMD intends to push into the market aggressively. We have seen them gain market share this year and expect them to gain even more,” said Jon Peddie, the head of Jon Peddie Research.

Ah, interesting. 1/8 DP is a bit disappointing, but not very relevant to enthusiasts. I'm also wondering if there is an artificial limit at play.

We've also come to learn that AMD changed the double-precision rate from 1/4 to 1/8 on the R9 290X, yielding a maximum .7 TFLOPS. The FirePro version of this configuration will support full-speed (1/2 rate) DP compute, giving professional users an incentive to spring for Hawaii's professional implementation.

Now that Anandtech's article is actually done, I've gotten to actually reading it. Great to know that it literally deems it's tests as not built to isolate R9 290x's deliberate benchmark length performance.

Anandtech R9 290x Review said:
A Note On Testing Methodologies & Sustained Performance

We also want to make quick note of our testing methodologies and how they are or are not impacted by temperature based throttling. For years we have done all of our GPU benchmarking by looping gaming benchmarks multiple times, both to combat the inherent run-to-run variation that we see in benchmarking, and more recently to serve as a warm-up activity for cards with temperature based throttling. While these methods have proved sufficient for the Radeon 7000 series, the GeForce 600 series, and even the GeForce 700 series, due to the laws of physics AMD's 95C throttle point takes longer to get to than NVIDIA's 80C throttle point. As a result it's harder to bring the 290X up to its sustained temperatures before the end of our benchmark runs. It will inevitably hit 95C in quiet mode, but not every benchmark runs long enough to reach that before the 3rd or 4th loop.

For the sake of consistency with past results we have not altered our benchmark methodology. However we wanted to be sure to point out this fact before getting to benchmarking, so that there’s no confusion over how we’re handling the matter. Consequently we believe our looping benchmarks run long enough to generally reach sustained performance numbers, but in all likelihood some of our numbers on the shortest benchmarks will skew low. For the next iteration of our benchmark suite we’re most likely going to need to institute a pre-heating phase for all cards to counter AMD’s 95C throttle point.

This is simply an artificial decision for market segmentation. Rainy beat me to it

Well congratulations to AMD for reaching whatever price point. But I think we all know this costs them in the long run. Brand recognition doesn't come easy, and this is a sure way to deter that from happening. If you're going to be smart (design an excellent GPU) then be smart the whole way. Don't walk up 20 inches from the finish line and cut your own achilles tendons. It's completely not self serving and AMD needs to be self serving if they want the appreciation, not condemnation, of their consumers.

Let met get this straight, did you just turn one company's ability to undercut the competition by $100 and offer a product that's faster into a negative?

Are PC gamers supposed to be happy to pay $100-450 extra for the brand name of a competitor? :whiste:

You say NV has strong brand recognition and because of it they can charge $100-450 extra for slower/similar performance, I say that in many cases NV charges an Apple-style premium that isn't justified (770 being a price example of a horribly overpriced card).

AMD is essentially selling a flawed product. But due to clever marketing of not announcing a baseclock.

The chip is anything but a marvel. Its simply too leaky and even with a 20% OC power consumption rises 200W. But I guess the smaller die was a nice checkbox for the marketing dept.

But thats just another lost oppotunity in AMDs long list of such. And with a year or so to 20nm. Its a long time to carry these blowtorches.

Spin harder and you might start a tornado.



Is this another one of your unformed opinions, just like last time when you said after-market versions of R9 280X cards will approach $400 USD, and that after-market R9 280X cards will be slower than 7970GE?

"Flawed product" that outperforms 780 and trades blows with the Titan for $550? Interesting way of downplaying the awesome price/performance. It's only a matter of time before after-market R9 290X cards come out.



When R9 290 OC trades blows with 780 OC for $449-479 (and flashed with Titan OC), the winner(s) will be brand agnostic PC gamers. NV will have to drop prices soon on 780 to $499 and replace 780Ti at the current 780 price. Awesome development for PC gaming.

The 290 has incredible potential. Give credit where it is due. But that cooler makes me just want to line up the AMD engineering staff and smack the dumb looks off their faces. To throw a cooler like that on an engineering feat like the 290? It's criminal. How does something like this get through? What are they thinking?
It's most likely deliberate.

Think about it. AMD has used the same design cooler for how many generations now? It's adequate, cost effective and gets the job done. But it isn't as capable as the aftermarket designs that will eventually follow. AMD can design a 6.2 billion transistor GPU that is the fastest in the world, but their engineers are incapable of coming up with a HSF design to equal or beat aftermarket coolers? I don't buy it.

What I've suspected for awhile now is that AMD deliberately sticks with their blower design because it isn't as good as aftermarket designs. This allows AIBs to come out with their own cooling designs to differentiate themselves. After awhile, the reference cards won't even be available anymore and all you will see in the market will be custom designs.

Remember, AMD doesn't sell cards themselves anymore. They supply the GPUs/reference cards and allow the AIBs to redesign the cooling, the PCBs and the components to suit themselves.

Personally, I think it's all part of their marketing plan.

Now that all crossfire communication happens straight over the PCI-E bus, would 2 of these cards in CF be severely bottlenecked on PCI-E 2.0 x8?

Might pick up a pair of non-x R290s when aftermarket cards hit, but if there's a big performance deficit on PCI-E 2.0 I'm going to pass.

And in the past this has led to their AIBs to design a completely worthless cooler that is technically no worse than stock cooling like XFX has done with it's entire 7xxx line and also its 280x.

If you don't set a baseline that is high, your AIBs can make sure to just barely meet that baseline and give your customers bad experiences just as well as you yourself do.

That's the reason for Nvidia's Greenlight program, which they implemented after the PR disaster that was 5xx aftermarket cards literally blowing up and melting down.


This is also seen in the fact that the MSI, Gigabyte, EVGA, etc aftermarket coolers for the cards that have an analogue of the Titan cooler as stock cooling were better coolers than the ones they designed for the 7970ghz edition, even though the 7970ghz edition dissipated the same or more watts of heat as the aforementioned cards.

]How many custom cards can you buy now? [/B]None? So reference is the only one we can relate to right now. Its a card running 94C nomatter what mode. Are you saying reference cards shouldnt work because they are reference? Broken products are obviously ok with you.
jumped 30 pages but how many gtx780Ti can you buy now

I saw someone who floated a theory that because Hawaii runs hot AMD didn't hand out carte blanche to AIBs to churn out their cooler designs at will and is perhaps wanting to vet them before allowing them to be used.

It makes some sense because some aftermarket coolers are actually atrocious and perform worse than reference. Some of the truly bad ones ignore proper VRM cooling which could be an RMA disaster waiting to happen with the hot running 290x.

We know there is a DCU2 coming as there is a SKU up on newegg already, a well known competent cooler, but have seen nothing else yet.

I hope this is actually the case, as I am truthfully looking to get a R9 290x with an good cooling solution to replace some of my 2x7970 and 2x7950s.

I was saddened that I couldn't just pick up a pre-order with Battlefield 4 and Battlefield 4 Premium after seeing the leaks and the early reviews.

Obviously also an nVidia hater. Since I first added focus to their problems between baseclock and boost. Since Hawaii is the first chip from AMD where you can actually read the boost clock and not just get no boost or all boost as result.

I find it amazing how diligent some people defend broken products to protect X/Y company.
show me a full GK not a core cut/crippled , like a full core , 1x cut $1000 ,2nd cut $650.00 give me a break.
a full GK =$550.00 today imo

With 1/2 DP they're really bringing the fight to Tesla, at least on the hardware end. I'm sure a lot of systems will stick with Nvidia no matter how much better AMD's hardware is for compute because they're already tied in to the CUDA ecosystem.

In farcry where the difference is, notice fan stopped at 65% anyway. Good or bad news?
Well it means for sure that if you put it at 100% you get every inch of performance from this card in all games.... if your case is well ventilated. Lol.

Well, i don't know the ventilation conditions of the test, but i posted this in reply to that Techpowerup graph. What probably happened is that the 290x can maintain this max boost clock during the play.

That is actually a decent theory. Though it would have been much better for PR if the card had been sufficiently cooled to unleash its full performance in the initial reviews.

Brilliant plan. Sell almost NONE of their reference cards due to the HSF "just" being good enough instead of excellence. It may have been deliberate, or just cutting costs where it's easiest to do so.
