ATI Chips Comparison Table E-mail

With more and more graphics chips being released every day it became very complicated for the user who does not follow the video card market to know the differences among all ATI graphic chips in the market today. To facilitate knowing and understanding the difference among major ATI chips, we have compiled the following table.

It is important to notice that starting 2007 both ATI and nVidia started referring to the memory clock of their video cards with the real clock rate used. In the past manufacturers referred the memory clocks with double their real clock rate, because DDR and subsequent technologies (DDR2, GDDR3, etc) allow the memory chip to transfer two data per clock cycle. So a video card with a memory chip running at 500 MHz would be referred as having a 1 GHz memory. In order to keep the compatibility of our table, we are still referring the memory clocks with the DDR naming convention - i.e. double the real clock rate - on cards with memories based on DDR or subsequent technologies.
