Help to choose a graphic card - Mem5 - 04-22-2012

Hi,

I need a new graphic card, and your help Smile

My budget is no more than $250. Just used for oclhashcat (no games).

As I understand the more important thing to check is the number given by

Quote:numberOfCores * ClockRate

I looked at this table : http://golubev.com/gpuest.htm and I saw 2 cards :

Quote:Radeon HD 5870
Cores : 1600
ClockRate : 850

This card seems powerful, but quite old (released in Sept 2009)

And :

Quote:Sapphire HD 7770 OC
Cores : 640
ClockRate : 1150 (OC)

This card seems less powerful, but recent (released in feb 2012)

I read somewhere that 7xxx family have maybe less cores, but they are more efficient/powerful than older family (5xxx).

Is it true for oclhashcat work ?
Which one would you take ? And why ?

Thank you for your help.

I would save some more money and then take the hd7970

Thanks for your answer but.. if I don't want to put so many money in it, which one should I choose ?

RE: Help to choose a graphic card - forumhero - 04-22-2012

of course hd 5870. it is faster in all counts

RE: Help to choose a graphic card - Mem5 - 04-22-2012

So whatever the family (5xxx,7xxx,..), the most important thing remains the largest ratio numberOfCores*ClockRate.

yes, exactly.
