What does "bits" mean in video cards?

PLEASE READ THIS:





Now that I caught your attention, I would like to explain what I'm talking about before you go all willy-nilly answering something different.





Well you know there's many different video cards on the market. Like an Nvidia Geforce 7600 256-bit.





What does the 'bit' mean? Also yes, I know my video cards to know that 7600 = only an idiot would buy this with the 9 series being out

What does "bits" mean in video cards?
256-bit refers to memory bus bandwidth on the graphic card. 256-bit is considered very good, coupled with GDDR3 ram.





Why this is mentioned on websites? Because some manufacturers use cheaper-to-make 128 or 64bit memory bus on cards. These often have 256-512mb ram and a very low price tag, so general public buys them thinking they got a bargain. But the low memory bandwidth kills all performance.





As a side note: 7600GT is not an idiots card. That award goes to 8600GTS and Radeon HD3650, u can easily buy something (bit older) for similar money thats LOT faster: 8800GTS 320mb.
