Radeon HD 7900 Launch set for December 22nd, 2011 - R1000 | Tahiti | GCN

From the rumblings on the Rage3D forum, it sounds like AMD might have a performance driver up their sleeves for the 79xx series on the way. The inconsistencies in the benches for 78xx series cards (putting them well above the 7970 is some scenarios - Toms Hardware) only serves to reinforce this. AMD is probably sitting on an egg for the Kepler launch. Not to say that the 78xx might get even more of a boost with the performance driver as well.

Should be an interesting few weeks to say the least.
 
Refined releases, performance drivers, Kepler launch just around the corner - I'm glad I didn't jump on this generation's wagon yet. As a spectator it's going to be amazing.

Next-gen just got hotter. Here's to hoping we get a downclocked 7990 in consoles :).

Jesus dude... no. You'll be lucky to get a downclocked Pitcairn.

Ok well im sold on the 7870. Will be quite an upgrade on my 6870. Only thing for me is, since this will go in an HTPC i will have to i guess wait a bit for the quietest one. Right now my 6870 does very well in everything i play it at, but in some instances(SWTOR), the fan goes on full blast and bothers the F outta me as it becomes the loudest thing in the room. So the 7870 will use less power, put out less heat, will get stressed way less than my 6870. WIN WIN for me.. only other thing right now seems to be the price.

Yep - this. I'm finally going to upgrade my crossfired 5850's when:

1) You find the quietest ones (hehe)
2) They hit $250 (soon, right? lol)
3) They don't go over 9.5", as that's all my HTPC case will allow without hard drive removal. None of this 9.75" due to extra plastic shroud crap

Well, Hardware Canucks was one I was thinking of. Got 1196 without touching volts http://www.hardwarecanucks.com/foru...165-amd-radeon-hd-7870-hd-7850-review-17.html

I think everybody pretty much hit 1150 though. Be advised by "pushing" I meant "approaching".

Careful with using cherry-picked top-bin review samples as an indicator.

I don't know how I would feel about that if it were true. If they suddenly released a driver that significantly improved the performance of my card across the board, it would be awesome. However, if they were just sitting on it, waiting to use it to take the wind out of Nvidia's sales, then it's bullshit. Don't play games with your customers.

What sites are those specialguy?

I just checked the official site, it says a 500w+ PSU is fine for a 7950 and like the 5850 it uses two 6 pin connectors.
Click to expand...
Yeah, no worries on the PSU. You'll be fine.
I wasn't 100% sure that the 550vx had a 6 and 6+2 pci power.

More importantly, it makes no sense for it to have been deliberate. It would have "taken the wind out of Nividia's sales" if the performance had been there day one too. All a deliberate neutering accomplishes was making some people wait and see what Kepler delivered.
 
Yeah, that is a much better way of putting it. I think it would great if you guys with 7xxx cards get an excellent increase, and I doubt they have been waiting to see what Kepler offers so they could drop a driver-bomb. Similarly though, I'm pretty sure early adopters would be pretty upset if AMD were to drop 7xxx prices significantly in April in response to Kepler, but that is whole different matter competitively speaking.
 
There is no doubt that drivers will improve some more considering GCN is wholly different from VLIW and likely leaves plenty room for a lot of tiny improvements over the time.

You guys heard that the last BF3 patch drastically improved 79xx performance, yeah? People were claiming they got 10-20 FPS more.

For anyone keeping score, we reran all of our numbers after the recent Battlefield 3 Radeon HD 7000 series performance patch. The results are virtually identical. While we don’t have official confirmation, we believe that DICE switched to a different FXAA codepath; however doing this doesn’t seem to have impacted the performance of the 7000 series, which is either a testament to AMD’s shader compiler, or proof that the overhead from FXAA is very low in the first place.

Same numbers in other reviews, didnt see any gains stand out.
 
Looks like we might see some single slot 7850's

Hey guys why am I getting artifacts when overclocking this card? I'm just touching the catalyst settings. I have the fan mode set to automatic and the power usage to max level..Do you guys think is a heating problem, should I lower the clocks speed?
 
At what clocks are you seeing the artifacts? If the stock clocks doesnt give you the same issue then you are driving it too hard.

Are you even monitoring the temperatures? Open GPU-Z sensor tab and see how high they are when the artifacts appear.

It's frequencies, temps, or both.

GPU clock at 1125 and memory 1575,the maximum available from the catalyts settings. I think I have to enable manual fan control up to 50% or lower those speeds.
 
Errr... you really shouldn't just choose the maximum that Cat lets you choose. Overclocking is being done step by step, i.e. start with the GPU clock, overclock it in, say, 10mhz steps, check for stability etc. and after you are done there you can start to overclock the memory.

Ok, will try that way. It's the first card I try to overclock. Thanks
 
AMD Radeon HD 7990 Clock Speeds, Chip-Configuration Surface

Closely trailing the launch of NVIDIA's GeForce GTX 680, and keeping up with its own streak of launching a new graphics card line each month since January, AMD will unveil its Radeon HD 7990 graphics card in April, or so it's reported. INPAI reports the clock-speed and chip-configuration of the upcoming dual-GPU monstrosity. The Radeon HD 7990 packs two 28 nm "Tahiti" GPUs as a "Crossfire on a stick" solution. The Tahiti chips will be clocked at 850 MHz (core), and 1250 MHz (5.00 GHz effective) memory.

The chip-configuration of each of the two Tahiti chips will be the same as that on the Radeon HD 7970, with 2048 Graphics CoreNext stream processors, 128 TMUs, 32 ROPs, and 384-bit wide GDDR5 memory interface, holding 3 GB of memory, each. The total memory on the card will hence be 6 GB. With the Radeon HD 7970 refusing to budge from its US $549 price-point, it's quite natural that the Radeon HD 7990 will be priced very high. It is gunning to retain the performance crown that's currently disputed between the Radeon HD 6990 and GeForce GTX 590.

Computerbase.de says its going to be $849 :/
 
Caught this on my RSS feed: Do AMD's Radeon HD 7000s Trade Image Quality For Performance?

C4IfW.gif


We did, in fact, find texture quality anomalies in AMD's new Radeon HD 7000 series, and we were originally concerned that history was repeating itself when we discovered the problem. If you've paid any attention to the graphics space over the past 10 years, you'll probably remember a time when ATI and Nvidia quietly played around with image quality, sacrificing visual fidelity for performance in order to help their products perform better in high-profile game benchmarks.

To be clear, the discrepancies we found on the Radeon HD 7000 cards aren’t obvious until you start poring over screen captures. With that in mind, we're still reminded of a time when some folks argued that optimizations are acceptable if they're not noticeable during game play. Despite this contrarian view, common sense won out in the court of public opinion and users made it clear that they wanted to see the output quality that the developer intended. Since then, it has been acceptable to give players the option to lower quality in exchange for performance, but the default setting is sacred, and we expect a similar experience across all graphics cards when it's employed.

Based on our original findings, it wasn’t a stretch to question if AMD had decided to try an old trick with the 7000 series, giving up hard-to-notice texture detail for a couple of frames per second in some games. We’re glad that AMD responded, clarified the situation, and provided proof in a fixed pre-release driver, plus a commitment to include that resolution in the upcoming Catalyst 12.4 WHQL driver. The driver it sent us for testing suggests that the issue can be solved without sacrificing performance.

As a tech journalist, it’s somewhat gratifying to identify a problem and then work with a vendor to get it fixed, and Tom’s Hardware has a rich history of this kind of investigative journalism.

I will say that I’m a bit surprised that the original findings we published in the Radeon HD 7870/7850 launch article didn’t seem to generate a significant amount of concern from our readers or the community. Toying with graphics quality is a slippery slope, and it should be something enthusiasts care about. Perhaps today's power users have more faith that these kinds of problems are nothing more than rare accidents that get fixed quickly and on their own. In this case, it appears the end result will probably mirror that optimistic expectation. But I think it’s important to stay diligent about defending the quality expectations we have of both AMD and Nvidia. Indeed, if Catalyst 12.4 goes live and the fix isn’t included, we’ll be the first to let you know.

Glad it's getting fixed, but it is kind of weird that it took so many months for anyone to notice and fix the issue.
 
Pick apart images with obvious driver optimization on, write large article about it, and never realize you can turn the option off. Great!
 
Breaking News: AMD HD 7970 Price Drop Incoming

After weeks of dealing with a retail price that put their HD 7970 in a no-win position against the GTX 680, it looks like AMD will finally cut their flagship card’s price.

Last month, we reported that AMD was sticking to their guns by retaining the HD 7970′s SRP at $549 regardless of NVIDIA’s higher performing and lower priced GTX 680. The reasoning behind this seemed to be quite simple: capitalize upon high end sales since NVIDIA’s production was struggling to keep up with demand.

At the time, we surmised that the only thing which would effectively push AMD to lower prices would be either improved GTX 680 availability or the possible release of lower priced Kepler derivatives. It looks like AMD’s bean counters may know something we don’t. If our moles are correct, the HD 7970 and possibly other cards in the HD 7000-series lineup are about to get a price cut.

The whispers we have heard from a number of sources peg the HD 7970′s new price at some point between $470 and $490 within the next few days. In our books, this would put AMD’s Tahiti XT in a favorable position against the GTX 680, particularly when the board partners’ numerous overclocked and custom cooled versions are taken into account.

What this means for the rest of AMD’s cards is anyone’s guess but as we previously discussed, cutting the price on one could very well have a cascade effect upon their whole product stack.

Naturally, as we receive more information it will be posted so stay tuned. It looks like the GPU Wars are just beginning to heat up!

It could either mean one of two things or both
1. 680 availability in the channel is increasing
2. 7970+ model incoming
 
Can't find a post about this in search, but the 79xx series drops in price tomorrow in response to Kepler.

http://www.rage3d.com/index.php?cat=75#newsid33988997

Beginning tomorrow, Monday April 16th, AMD Radeon HD 7900 series cards will be reduced in price. The AMD Radeon HD 7950 will begin at an SEP of USD$399 and the AMD Radeon HD 7970 will start at an SEP of USD$479.

Additionally, the 7900 series cards will be bundled with 3 free games - DiRT Showdown, Nexuiz and Deus Ex: Human Revolution with DLC The Missing Link content included.

Finally, the AMD Radeon HD 7770 GHz Edition has been price dropped too, now beginning at an SEP of USD$139.

The price wars begin, and obviously AMD have a notion of what the next release of NVIDIA's Kepler is going to look like and are adjusting price points to suit. Given NVIDIA's supply issues courtesy of TSMC's production problems, AMD have had free reign to keep their prices solid; could this be an indication that production issues are resolved?

No word on if early adopters are eligible for rebates on their now $70 overpriced cards, but that's the trouble with early adopting - the bleeding edge cuts two ways, sometimes.

Fair drop if you ask me.
 
Good drops if true. 7950 OC's fantastic once limit is removed, finally some interesting compeition. Glad on 7770 if true also.
