SMOOTHVISION™ HD
is an antialiasing solution that raises the bar for
image quality using programmable multi-sampling methods to post-
process graphics before they are displayed.
SMARTSHADER™ HD is a new technology allows specialized high
precision graphics programs to be run on the RADEON® X800 MAC
EDITION VPU rather than the system processor. Developers can easily
create amazing new graphics effects while maintaining a high level of
performance.
HYPER Z™ HD makes Z-buffer bandwidth usage more efficient by
decreasing the amount of information sent to the frame buffer at higher
resolutions than ever before.
