Will CF 5670 + 6870 slow down ?

post #1 of 11
Thread Starter 
Hi, i m just wondering will it slow down the performance if cross fire my SAPPHIRE FleX HD 5670 1GB GDDR5 with future generation of display cards ?

i mean lets say in the future i add SAPPHIRE FleX HD 6870 1GB GDDE5 onto my Biostar TZ68A+

5670 : (http://www.sapphiretech.com/presenta...n=&lid=1&leg=0)
GPU 775 MHz Core Clock
40 nm Chip
400 x Stream Processors
Memory 1024 MB Size
128 -bit GDDR5
4000 MHz Effective

6870 : (http://www.sapphiretech.com/presenta...n=&lid=1&leg=0)
GPU 900 MHz Core Clock
40 nm Chip
1120 x Stream Processors
Memory 1024 MB Size
256 -bit GDDR5
4200 MHz Effective


as you can see that these two GPU & memory spec r different~ will my old 5670 pulling 6870 leg such as in the case of 667mhz RAM + 555mhz RAM makes the RAM running slower on 555mhz joinly instead of faster 667mhz?

also since individually they both support Eyefinity, but if cross fire together will they join their Eyefinity function together into bigger screen like HD5870 (eyefinity x6) or nope it doesnt work that way ?

i m from the generation of windows 3.1 and to be honest i never really built a pc before as my 1st was built ready then my 2nd is laptop in 2001 although i do follow IT trend abit

any input are welcome, many thanks!

I'm pretty sure you can only CF cards in the same series (as in 5800 or 6800). Someone correct me if I'm wrong.

You can't crossfire cards that are of a different generation, as others have already stated. Sorry.

Its not happening mate.
Not possible to crossfire those two cards.

And seen as your motherboard shows no mention of hydralogix then thats not gona be an option either.

This. Although I know HIS released either a 6870 or a 6970 or something in that with the chip onboard so you could always go for that. As far as I know though, it's not worth it. More of a proof-of-concept/gimmick rather than a practical feature.

Why would you even want to CF 5670 and 6870? A 6870 is more than twice as fast as a 5670.
