Enter the brand new
HD 4890 1GB, a card that builds upon the HD 4870 with increased clock speeds
under its belt and supposedly bucket loads of overclocking potential.
Essentially, this is exactly what the name suggests: an overclocked HD 4870
with the new designation of RV790. This sticks quite well with what we
mentioned about modified versions of existing technologies being used to cement
a company’s place in the market. Indeed, it seems like ATI has really hit its
stride with their current 55nm cores and they are making good use of them once
again. @ Hardware Canucks
