The focus of our conversation with ATI was dealing with the misconceptions brought about by NVIDIA during the GeForce FX launch. ATI essentially feels that the RADEON 9700 is a more balanced solution than GeForce FX, which doesn’t have the bandwidth to perform many of the operations it’s boasting at an acceptable frame rate.

For instance, NVIDIA is proud to claim that GeForce FX boasts pixel and vertex shaders that go beyond DirectX 9.0’s specs, yet a 400-500MHz chip with 8 pixel pipelines running very long shaders would spend all of its time in geometry, bringing frame rate to a crawl. ATI feels that with RADEON 9700’s multi-pass capability, having native support for thousands of shaders is useless, as the RADEON 9700 can loopback to perform those operations. ATI ran a demonstration of a space fighter that was rendered using this technique.

As far as NVIDIA’s bandwidth claims of GeForce FX’s 48GB/sec memory bandwidth, ATI states that the color compression in their HYPERZ III technology performs the same thing today, and with all of the techniques they use in RADEON 9700, they could claim bandwidth of nearly100GB/sec, but if they did so no one would believe them, hence they’ve stood with offering just shy of 20GB/sec of bandwidth.
