[Tom's Hardware] Do AMD's Radeon HD 7000s Trade Image Quality For Performance?

post #1 of 84

Quote:
We discovered blurry textures when we reviewed the Radeon HD 7800s, so now we're performing an in-depth investigation. Why does the Radeon HD 6000 series demonstrate crisper image quality? Is performance affected? Does AMD know about the issue?

When we were testing the Pitcairn-based Radeon HD 7800 cards for last month's launch, we stumbled upon image quality issues with AMD’s two most recent boards. Specifically, we noticed textures in popular games that appeared blurrier on all of the Radeon HD 7000s compared to the prior-generation offerings. And this was using identical image quality settings in the software driver and the games we were testing.
Very interesting indeed.

Nvidias current flagship didn't surpass the 7970 as much as anticipated.

Nvidias stuck in a rut waiting for 28nm to mature so they have no additional competition for the rest of amds line up.

So...

These little conspiracy theories will pop up to make green team feel better...thumb.gif

Except it isn't some conspiracy theory, it was a fact. And they fixed it with the new drivers.

No it isn't but it only differs 2 or 3 fps so i wouldn't really call that anything significant.

I have consistently defended TH against the mindless anti-toms bashers, but you know what? It's write-ups like this that give those people credit. First off, the title of the article is sensationalist, as the results clearly showed that AMD was not trading IQ for performance.

But this was the best part:
Quote:
To be clear, the discrepancies we found on the Radeon HD 7000 cards aren’t obvious until you start poring over screen captures.

And this made me laugh:
Quote:
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.

Probably for the reason in the first quote above. And look at how blown-up and pixelated you had to make your screen cap portions to show people a difference. Take that, shrink it back to the native image resolution, and put it into a motion shot and no one would notice a difference. That's why you can use things like blurring to compensate for high-demand texture rendering during fast action shots and the user would never know the tricks you pulled in quality of textures.

And I significantly doubt the effect this guy had on AMDs decision to release an updated driver. They're new cards with new games and new drivers--takes a while to get the bugs figured out. I don't see what about this was some big investigative journalism piece.

The best part of this is laughing at how pixelated the screen caps they're showing as "proof" of this quality difference. rolleyes.gif If anything, the best argument you can make to support your claim is showing native-res images side-by-side. If no one notices a difference then all you've accomplished is wasting everyone's time.
