A lot has changed since November though... drivers have really matured and games have been optimized.
The Best Graphics Cards: Full AMD and Nvidia GPU Comparison with Latest Drivers
- Thread starter Steve
- Start date
First of all, Nice article, I have some doubts , HD 7970 GHZ is fast, but some comparison videos I watched shows smoother gameplay experience, no shuttering or lag in GTX 680 as well as GTX 680 provides better color saturation, if I look at water or human faces its better in GTX 680 than in 7970. Also whether you have enabled PHYSX, or any other Nvidia specific things? because that will reduce the fps too. Because the difference seems unbelievable. Generally GTX 680 provides much more crisp and clear images than 7970?why?

You probably could've a couple months ago, this is an "old" topic so it won't show on trend and unless someone is following this you won't get a reply
That and half of what he said simply isn't true so I am guessing no one really wanted to deal with it
Hello Steve & Kibaruk,
Thanks to both of you for replying. I want to buy a GPU, that is the reason I came here. Please see the below video 7970 & GTX 680 side by side comparision, I have watched some videos before asking it here,

Thanks.

Too much is unknown about the video such as what driver version was used. Furthermore the GTX 680 is NOT faster than the 7970 in BF3 and we test the same section of the game that this video is based on.
Not sure there is any need to update the article. How much is the 13.4 driver going to change this article? We are testing the 7990 this week and that review is based on the 13.3 and 13.5 beta drivers, results are much the same for cards like the 7970 as they are in this article.
AMD is working on a "Frame Pacing Prototype" driver right now which we have the second version of so once that driver is complete we will likely do an article that looks at fps and frame time performance.

Well, isnt the latest driver 13.3 beta? It hasnt been updated since March 20, 2013. As for 13.5, is that a typo or did you all get it early? Isnt that Frame Pacing Prototype the latency improvements in 13.3 beta?

That's the 7990 driver.

Yeah there is an NDA in place and it is lifted on the 24th so keep your eye out for that one, we have done lots of testing for you

Yeah, I have seen 2. One from TS and another from Toms Hardware. I am yet to see AnandTech's. Latency has been an issue for AMD every since they have launched the 7000 series. The 13.3 beta driver has been in beta stage since January. It is said to resolve those frame latency issues.

PCPerspective used Catalyst 13.5 (beta 2 I think), which still shows marked propensity towards CFX stutter. PCPer also tested the prototype 2 driver which does seem to alleviate the issues of frame latency- the down side is that the driver wont be available until June-July. Review sites were cautioned against using the P2 driver in HD 7990 reviews based on immaturity and drops in performance (frame rate).
Yeah the new driver shows good promise, but its 3 months away. Still I will reduce 350$ for their gaming bundle and only see it as a 650$ card, so AMD 7990 is more than worth the money.

AMD released the card at the right time I think. If nVidia releases the 790 in the rumored May-June timeframe, it may be tough for AMD, but this driver will help to combat nVidia. If the rumor about the 780 using Tesla K20x cores is true, then we could speculate the 790 will be that x2. AMD will really need to ramp up their game from that point on.

Maybe, but unlikely IMO. AMD will at least get over the hump of inconsistencies in Crossfire (profiling notwithstanding), but the elimination of partially rendered frames will count against AMD cards in benchmarking where average framerate is the overriding factor since those average framerates will drop. The alternative is that AMD petition review sites to use separate drivers for single and multi-GPU
You mean the hullabaloo the 3DCenter article caused, and the subsequent guesswork at BSN and Fudzilla based on 3DC's musings?
3DC tend to churn out these extrapolations every few months (they assumed the GTX Titan would follow Nvidia's naming convention- I.e. GTX 780 late last year for instance). The timing of BSN and Fudzilla's articles on the eve of the HD 7990 launch I don't think is coincidental.
As far as I am aware, the only part being added to the product stack is a "Titan LE" SKU ( an analogue of the Tesla K20/K20C with one memory controller and a further SMX fused off), with GK104/106 parts moving down one tier from their present positions to accommodate the LE part (GTX 780?). K20X is essentially the GTX Titan -same core count and memory interface, but binned for low voltage operation.
I would think it extremely unlikely that Nvidia would put up a dual-GK110 card. 2 x 561mm^2 GPUs would make it unviable on cost. Binning for compatible GPUs would also overlap the same requirement used for Tesla K20X and Quadro K6000 whose selling prices per GPU are 3-4 times that of GeForce branding. A dual GK104 (or GK114) based on higher clocks - or more likely, the same base clock and a much higher boost would seem eminently doable given the power usage headroom advantage GK104 has over Tahiti.

Hmm. Interesting. I read about the 700 series rumor on WCCFtech. They sometimes get stuff wrong also. The cost part of the 790 I didnt think of. You are right. But then that whole rumor should be dumped in the trash... a cut down K20x core cant get the price down to $500 (780). As for the K6000, isnt the high price due to 6GB of ECC GDDR5 and the "quality" drivers?

For Nvidia pro cards, the price premium is (in descending order):
1. 24/7 365 day support (phone/on-site/guaranteed like-for-like warranty replacement for three years)
2. Drivers and software ( e.g. CompleX, SceniX, OptiX, 3D Vision Pro )
3. More stringent binning/ run-time validation of GPU and memory IC's
Memory IC's aren't overly expensive in the context of a $3-5K pro board. Here's a round-up cards and their associated BoM (Bill of Materials). Bear in mind that 6Gb/sec GDDR5 was fairly new (read: expensive) a couple of years ago, as was the current 7Gb/sec modules when the were first introduced last year.
