AMD Radeon 6000 Series Image Quality Analysis
This article will conduct an image quality analysis on the Radeon 6850 along with comparing Fermi and 5000 architectures to it. The findings on the 6850 also apply to the 6900 series, though EQAA will not be covered as it’s unique to the latter. I plan to cover this feature in the future.
For background reading I highly recommend the past image quality articles I’ve written:
- nVidia 400 series image quality analysis.
- ATi 5000 series image quality analysis.
- nVidia GT200 series AA investigation.
- ATi 4000 series AA investigation.
- ATi vs nVidia image quality comparison.
