Jaggies testing

Well looking at those same 3 images, we can see that both ATI and NVIDIA develop jaggies while in the yellow zone. This means that their ability to deinterlace isn't able to prevent anti-aliasing at oblique angles.

But wait? Look at the XGI image again:

XGI

It's perfect. Since the XGI Volari 8300 has edge-adaptive deinterlacing, it is providing the best results in this portion of the test. Part of the reason why XGI does well with video is that the development costs required to do good video are not as high as they are for 3D. XGI is putting a substantial part of their effort into improving video quality, and their engineers are formerly of Trident, a company that now manufacturers video processors used by Sony, Samsung, and Metz televisions.

Under Jaggies 2, all three properly smooth the first two bars, but none are able to keep the third line smooth.

XGI

Although all three earn the same numerical score, the XGI still does marginally better in preventing the aliasing.

Moving onto the waving flag, all three are able to produce images where jaggies on the red and white stripes are minimized. None of the three GPUs are able to completely remove the jaggies but XGI and NVIDIA do a better job than ATI.

XGI

Among the three GPUs, ATI does the worst. NVIDIA and XGI perform similarly with some portions of the flag looking better on NVIDIA and some portions looking better on XGI.

Score:
1st place – XGI (13 points)
2nd place - NVIDIA (11 points)
3rd place - ATI (6 points)

Interpretation:
When it comes to de-interlacing 30 fps content such as TV shows, the $50 XGI bests the GeForce 6600 and Radeon X800 by a substantial amount.
