So, a video card with a memory chip running at 500 MHz would be referred to as having a 1 GHz memory. In order to make our table comparable to older chips, we still use the effective memory clock and not the real memory clock. In the past, manufacturers referred to the memory clocks with double (or quadruple) their real clock rate, because DDR and other technologies based on it (DDR2, GDDR3, etc.) allow the memory chip to transfer two data blocks per clock cycle, while GDDR5 memories allow the memory chip to transfer four data data blocks per clock cycle.

It is important to note that beginning in 2007, both AMD (ATI) and NVIDIA started referring to the memory clock of their video cards with the real clock rate used. Includes all improvements found in the AMD Catalyst 14.6 RC driver AMD CrossFire and AMD Radeon Dual Graphics profile update for Plants vs. To facilitate knowing and understanding the differences among major AMD (ATI) chips, we have compiled the following table. 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 AMD (ATI) graphic chips on the market today.
