Overclocked: EVGA GeForce GTX 280 FTW
EVGA was kind enough to send us a card so that we could test SLI and take a look at overclocked performance of the GTX 280. Their card uses the stock HSF, but has fairly high clock speeds:
| Stock GTX 280 | EVGA GeForce GTX 280 FTW | % Increase | |
| GPU Clock | 602MHz | 670MHz | 11.3% |
| Shader Clock | 1296MHz | 1458MHz | 12.5% |
| Memory Clock | 1107MHz | 1215MHz | 9.8% |
We ran a few quick tests to look at overclocking performance and we saw about an 8% to 12% increase in a few games at high resolutions over the stock clocked card. Here is a quick look at a couple of these tests.
Crysis is one of many benchmarks where the GTX 280 falls behind the GeForce 9800 GX2, unfortunately even an overclocked GTX 280 will not dethrone the almighty GX2.
Oblivion on the other hand showcases a memory bandwidth limitation of the GX2 at ultra high resolutions, here we see an 11% performance advantage from the overclocked EVGA card. Given that the EVGA card has an average clock speed increase of 11.2%, this sort of a performance gain isn't bad at all. Even at 1920 x 1200 we see a 9% performance improvement from the overclocked card.
It seems as if the GTX 280 and GTX 260 can stand to benefit from overclocking very well.

Thanks for the heads up, you're right about G92 only having 4 ROPs, I've corrected the image and references in the article. I also clarified the GeForce FX statement, it definitely fell behind for more reasons than just memory bandwidth, but the point was that NVIDIA has been trying to go down this path for a while now.Take care,
Anand

Thanks for correcting. Still, the paragraph about the FX is a bit odd imho. Lack of bandwidth really was the least of its problem, it was a too complicated core with actually lots of texturing power, and sacrificed raw compute power for more programmability in the compute core (which was its biggest problem).Arbie - Monday, June 16, 2008 - link
I appreciate the in-depth look at the architecture, but what really matters to me are graphics performance, heat, and noise. You addressed the card's idle power dissipation but only in full-system terms, which masks a lot. Will it really draw 25W in idle under WinXP?And this highly detailed review does not even mention noise! That's very disappointing. I'm ready to buy this card, but Tom's finds their samples terribly noisy. I was hoping and expecting Anandtech to talk about this.

I've updated the article with some thoughts on noise. It's definitely loud under load, not GeForce FX loud but the fan does move a lot of air. It's the loudest thing in my office by far once you get the GPU temps high enough.From the updated article:
"Cooling NVIDIA's hottest card isn't easy and you can definitely hear the beast moving air. At idle, the GPU is as quiet as any other high-end NVIDIA GPU. Under load, as the GTX 280 heats up the fan spins faster and moves much more air, which quickly becomes audible. It's not GeForce FX annoying, but it's not as quiet as other high-end NVIDIA GPUs; then again, there are 1.4 billion transistors switching in there. If you have a silent PC, the GTX 280 will definitely un-silence it and put out enough heat to make the rest of your fans work harder. If you're used to a GeForce 8800 GTX, GTS or GT, the noise will bother you. The problem is that returning to idle from gaming for a couple of hours results in a fan that doesn't want to spin down as low as when you first turned your machine on.
While it's impressive that NVIDIA built this chip on a 65nm process, it desperately needs to move to 55nm."

I agree with what Darkryft said about wanting a card that absolutely without a doubt, stomps the 8800GTX. So far that hasn't happened as the GX2 and GT200 hardly do either. The only thing they proved with the G90 and G92 is that they know how to cut costs.Well thanks for making me feel like such a smart consumer as it's going on 2 years with my 8800GTX and it still owns 90% of the games I play.
P.S. It looks like Nvidia has quietly discontinued the 8800GTX as it's no longer on major retail sites.

Ya the 640 8800 gts also. No Sli for me lol.wiper - Monday, June 16, 2008 - link
What about noise ? Other reviews show mixed data. One says it's another dustblower, others says the noise level is ok.Zak - Monday, June 16, 2008 - link
First thing though, don't rely entirely on spell checker:)) Page 4 "Derek Gets Technical": "borrowing terminology from weaving was cleaver" I believe you meant "clever"?As darkryft pointed out:
"In my opinion, for $650, I want to see some f-ing God-like performance."
Why would anyone pay $650 for this? Ugh? This is probably THE disappointment of the year:(((

On techpowerups review it seemed to pull much bigger numbers but they were using xp sp2.http://www.techpowerup.com/reviews/Point_Of_View/G...">http://www.techpowerup.com/reviews/Point_Of_View/G...

Pfft, title says it all. Let's hope that driver updates widen the gap between previous high end products. Otherwise, I'll pass on this one.
