The HD 4770 is the
poster boy for the changing face of ATI. They have forgone the push for a
power-hungry monolithic architecture and have instead focused their energies on
scalable, more compact GPU cores which can be used for multiple cards in
various price ranges. This was first accomplished with the 55nm HD 4800-series
and later perfected with the lower end HD 4600 series and more recently the HD
4890 1GB. As technology has progressed, so too has ATI’s shift towards a more
price and efficiency-conscious manufacturing processes. @ Hardware Canucks
