im really confused about RADEON cards..like why is hd 6850 better that 7770...??

i have a GTS 450 at home..and im thinking that i should upgrade it now..
my target is hd 6770..but when i saw hd 7770 i already think that its more powerful..
but when i googled it i saw that 6850 is more powerful that 7770..????im confused
is radeon cards don't base their power on there name?? like nvidia cards??

like this one

GTX 550 -GTX 560 - GTX 580 and sooo on...

ohhh i see ..but a lot of people are choosing 6870/6970 instead of 7770???

The naming convention for the Radeon HD WXYZ where W is the generation, X is the tier (6 and lower is budget lines, 7 is the mainstream line, 8 is the performance line, and 9 is a dual core GPU extreme line), Y is the subcategory where higher numbers are better, and Z is the variant typically 0 but possibly 5 in certain cards.

So when comparing relative performance within the same generation is easy, however, cross generations is a bit more difficult just like a GTX 580 is more powerful than a GTX 480.

The number is the same system as nvidia's except theres an 0 at the end and AMD's line is more spread out. generally there are 2 or more cards per tier.
6750 6770 6850 6870
6th generation cards with 7 being less than 8 and 50s being less than 70s.

that was a very good explanation on the radeon cards..thats why 6850 is better than 7770.. thanks that was a very useful information for me..
