Uns fiel zu Beginn der Tests auf, dass der anisotrope Filter der HD-6800-Karten im Vergleich mit einer Radeon HD 5870 stärker flimmert. Nach Rücksprache mit AMD teilte man uns mit, dass die Standardeinstellung "Qualität" aggressiver filtert als der bisherige Treiberstandard (A.I. Standard; dort seien die Texturfilteroptimierungen bei der HD-5800-Reihe bereits deaktiviert)
http://www.pcgameshardware.de/aid,79...e/Test/?page=4

They recognized that the new standard "quality" setting has more shimmering than the old AI standard setting. AMD confirmed that optimizations are more aggressive in the new quality setting.

So AMD fixed the banding problem, but increased sample optimizations in the driver default setting, which is used by the most reviewers. This probably gives a significant performance gain over GeForce and the old Radeon HD 5000 @ Cat 10.9.

In all, you should be pleased about the new options as its offering more transparency.
Yes, it's great for your customers.
But my question is: Why do you change the image quality of the default setting? Quality is not as good as the old setting. I hope the reason was not nVidia's Quality. Because you didn't complain about it over the last 4 years...

I've waded through 30-40 pages or so dealing mostly with bickering about a benchmark with no predictive ability, and a feature with little to no current relevance (and judging from people on these very boards involved with art creation, rather murky prospects going forward as well).

If this is Barts "problem", I'd say it doesn't have any. I'm far more interested in an analysis of organization vs. performance, and figuring out how it achieves its apparent improvements in efficiency overall.

So, european users, which country has the cheapest cards at the moment, and do they ship to other EU countries?
At least here in Finland only one shop has them listed, not in stock, and the prices are skyhigh (240€+)

Forgive me if this has already been asked (coming into this very long thread late), but I'm pretty confused about the 5770 situation. Is it confirmed that 5770/5750 is going to be rebranded as the 6770/6750? All the reviews seem to be pretty cagey on what will actually happen to the name.

It's been confirmed that 5700-series will continue to exist, and will not be renamed (at least 'till the end of the year)

Rick Bergman was mentioning that the 6 series launch this year (40nm) consists of 6900s (Cayman + Antilles), 6800s (Barts), 6500s (Turks), and 6300s (Caicos?)


6700's probably saved for a 28nm shrink (Note: 4770) with 128-bit bus and such. Pipe cleaner?

Dave, are you able to confirm whether the ref boards tested are 6 or 8 layer pcbs?

First pricing spotted in my home country of Serbia. 210 Euros for Gigabyte 6870.

Not bad, i expected little higher.

Nice, ~40 euros cheaper than Finland (our VAT is 23%)

Maybe its some early promotion, who knows.
(our taxes are 18%)

It's not just the GTX460, it's every card in the review except Barts-based. And yes, I think with a ~centred upon $200 range of $20 increments for the key cards being reviewed, from $170-$250, a 10% increase in performance over a few months makes such a cack-handed review useless.

Wow, reducing the quality of default texture filtering on Evergreen is exactly what everyone was asking for

Wow! AMD really fought hard for every sq.mm in Barts.

Hi Dave,

That's why we headlined this section of our article "Neuerungen beim anisotropen Filter " which I would into "Anisotropic Filtering: What's new". And AMDs better angle-invariance is not exactly new, if I am not mistaken, but rather a thing we've come to enjoy for over a year now.

Wow that's a vast difference for such a measly gap.

I do not understand this nitpicking about the AF. The Banding is gone, HQ is available and the cards just fly and make everything NV sells from 460 to 480 obsolete. AMD has once again delieverd an absolute dominating card. I can´t wait for Cayman.

I think that R5870 doesn't show its full strength. Perhaps the drivers. That creates the illusion that R6870 is close enough.

I'm disappointed there's been so little information on Cayman. C'mon AMD, some of us want to know about the top end cards! We're going to have to do another month of this excruciating speculation?

Yes. It's interesting, that early reviewers slides contained some HD6900-hints:



but it was removed in the final version:

We all know that when it comes to angle dependency , there was no difference even between HD 4000 and G80 , GT200 in that regard .

Hmm, what's that, Gen 8 for Cayman, not Gen 7? A step at least as big as from 6 to 7?

With that earlier hint from the Anandtech article that 16 SIMDs with 16 ROPs is within 2% of the performance of 14 SIMDs and 32 ROPs, it seems there's a serious problem with ROP efficiency. Maybe that "scalability" problem will be fixed in Cayman.

And maybe that problem isn't just ROPs but rasterisation and thread generation.

Hm, are 16 extra ROPs cheaper than two SIMDs?
