Hey guys,

What's the current state of things on the 58xx vs 68xx series cards? 

I know that 58xx cards used to be much faster for bitmining than their 68xx counterparts. 
Is that still the case or have updated drivers, etc. fixed the problem? 

Thanks

The 58XX cards are just physically more powerful than their 68XX counterparts, so they always be a bit faster at bitcoin mining.

the 6xxx series is just a re bandaged 5xxx series. Some new cards ,but for the most part they are just old cards with updates from the 6xxx series.

58xx is discontinued, so its hard to find new one.

The stats I've seen say 325/393 MH/s for 5850/5870 vs 217/278 MH/s for 6850/6870. 

Does that jibe with current performance using the latest mining software/SDK/kernels?

I stuck with the 58xx series myself. All were 5850's bar one 5870.

I just recently sold them for virtually the same price that I purchased them new to a fellow miner.

will have to look into those... can anyone compare the 58xx cards to the 69xx cards for me? how do they stack up?

apparently the 68XX are more effecient on power/hash than the 58XX series.

More efficient of power but less efficient in hashing so 58xx series = greater profit still.
5830 / 5850 is sweet spot.  I have 4 more 5830s unopened waiting for a mobo and junk... and then I'll have 8 of them mining at about 2600 mhash

False. The hardware is different (the 6xxx have had hardware stripped off as compared to the 5xxx).

How do you achieve 325Mhash/s on multiple 5830s? Like, how's your cooling set up? I'm assuming you're running them at a tad over 1GHz core and around 300-340MHz memory?  That's what it would take for mine but the temps aren't comfortably sustainable so I ease back a bit. Using phoenix 1.6.2/phatk2 on linuxcoin btw

I have 1020 / 320 mem and aggression at about 8 or 9 with fans at 80% and they have been stable
This is in a FULL tower antec 1200 case with plenty of airflow in an air conditioned room.  Cards stay at about 70c

The 6870 is the only real 68xx mining card. At the current prices of around 155 they don't compare to a 5830. In the future hopefully the price will go down though Smiley

Yeah pound for pound, the 68xx cards are simply more expensive.

With the huge demand for the 58xx series with regards to it's number crunching skills, do you think that they will come back into production? Or can you see GPU cards that are more geared towards such things as mining than actual graphics?

The only reason why there's a "huge" demand is because they totally underpriced compared to the 6xxx, and they are underpriced precisely because AMD's getting rid of them, not because they're actually cheaper to produce. AFAIK they'll start soon (or maybe they already started, I don't follow this too closely) the production of their next GPUs, so of course they're not restarting the production of 5xxxs.
FYI the 6xxx series crunches just as well, it's just that you need to compare what's comparable: the 6870 isn't the successor of the 5870, the 6970 is.

The best price/performance/watt is 5850 ( around 380-400 MH/s, @930+ core ). 6970 is too expensive to buy ( at least for me ). Break even would be at least couple of months.

This guy is correct. Eventually when the 7xxx series comes out the 6xxx series will see a drop in price and become just as effective.
