DRAM Rated Speed
In addition to different DRAM technologies used in video cards, different cards also sometimes use different speeds of memory. This is relevant mostly for the older technologies such as FPM and EDO DRAM. Some cards using regular DRAM use, say, 60 ns access time DRAM and others may use 50 or 40 ns DRAM. Faster memory here leads to increased bandwidth; the difference in overall performance can be significant but usually isn't that great. The memory type (DRAM, EDO, VRAM etc.) is usually more important as a distinguishing factor.
Note: Some manufacturers use
different speeds of DRAM on retail and OEM versions of their cards. See
here for more on retail vs. OEM.
