How come some 256mb cost more than 512mb video cards?

That's when both of them use the same type of slot and are from the same company too! Do some of the 256mb's perform better than some of the 512mb's?

Yes, plenty of cards with 256 Mb of VRAM perform better than cards with 512 Mb. There are more things to a graphics card then the amount of onboard memory, such as pixel pipelines, frequency's and memory bus. Of course there are lots of other factors, but those are some main ones to look for.
 
Like he said above, 512 ram does not mean the card will perform better then the card with 256, nor does 256 mean it will perform better than 128. There are more factors to determine how a card will perform.
 
hrmmm

i got a 6800 XT it performs well as a 256 card but i was just wondering as to why does video memory matter and my mem clock frequency is 1000mhz with a 350mhz core is that good?

gddre does that couant with the video memory and what games will really put this video ram to the test?
 
because a 6200 with 256mb would get crushed by a 6600gt with 128mb... thats why :)
as long as you have dual channel system memory that has half-way decent specs, and preferably 1gb or higher then the amount of video memory is normally compromised by the system memory.
i mean a 6200 with 64-bit memory running at 400mhz has slower memory than my system memory.
a 6600gt however, has 128-bit memory to match my dual channel system memory, and it runs at nearly double the frequency of my system memory... which is why more video memory is better for higher qualities in games sometimes.

these are the reasons i got a card with super fast memory (more than 4 times as fast as my system memory) and 512mb of it.

Video memory matters just like system memory matters, except video memory stores stuff only for the video card.

Also, regarding your core clock/mem clock. You cant just compare those speeds with other cards. Ofcourse the higher the speeds the better, but that's only with the same class of cards.
