Video cards

Back to Technical Information

Video card names and numbers do follow a some form of logic:
 * e.g. nVidia 7 series has the following cards: 7100, 7200, 7300, 7400, 7600, 7800, 7900 and 7950 (excluding the TC / GT / GTS / GTX etc suffixes.)

Analyzing the nVidia 7600 card name:
 * the first digit: in this case, 7 means it is a member of the 7th generation (or series) of video cards by that manufacturer
 * the second digit: in this case, 6 signifies the performance range in relation to its generation
 * the third and fourth digits usually signify some exotic variety of the card (one example would be the nVidia 7950 which actually 2x7900 chips on the same card)

Generally speaking, nVidia cards rank as follows:
 * High performance: 7950, 7900, 7800
 * Mainstream performance: 7600
 * Entry level performance: 7400, 7300
 * Low performance: 7200, 7100

However, this is only useful for that particular generation of cards (7th). Below is a ranking of both 6th and 7th generation cards, from highest performance to lowest:


 * 7950 > 7900 > 7800 > 6800 > 7600 > 6600 > 7300 > 6200

and a list which includes some GT / GTS / GTX suffixes:


 * 7950 > 7900 > 7800 GTX > 6800 GS > 6800 GT > 7600 GT > 7600 GS > 6600 GT > 6600 > 7300 GT > 7300 > 7200

Unfortunately the GT / GTS / GTX suffixes do not always respect the same rules


 * e.g. 8th series: 8800 Ultra > 8800 GTX > 8800 GT > 8800 GTS > 8800 GS > 8600 GTS > 8600 GT > 8500 GT > 8400


 * e.g. 6th series: 6800 GS > 6800 GT > 6600 GT > 6600 > 6200
