There are a lot of them, some in this thread.  The early reports seemed to indicate a die shrink.  The later ones now indicate only the low end OEM garbage will be a die shrink rebadge.  I agree with you (and had stated it in the past) IF the 7850 is a VLIW4 on 28nm it will be a monster card.  Sadly that doesn't seem to be the case.

If that's the case, then I'm really disappointed.  I'm quite reluctant to jump into FPGA's anytime in the near future, so I was hoping I could get some power efficient cards in the meantime.  Grrr.

I have to break it to you but those number are pure crap for a 5970.  Not just against what I have gotten but against what lots of other people have gotten.  The limit on each card varies but my slowest card is running 820Mhz/160Mhz.  3x5970 in open air rig pulls 870W at the wall (measured over 3 days using kill-a-watt).  Backing out 100W for the MB, power supply inefficiency, CPU, RAM, etc that puts each card @ roughly 250W a piece.  That is w/ cgminer 2.1.0 running on Linux w/ 11.6 drivers & 2.4 SDK.

If you aren't getting AT LEAST 700MH/s you are doing something horribly wrong.  Note: 700MH/s isn't "good" it is just barely acceptable.

My math was bad in my previous post.  340x 2 = 680, not 640.  That's what happens when you've been up all night without sleep  Grin

Most of my 5970's I have been running at 800Mhz, but stability has sucked (suckage = a stalled miner once in three days), so recently I've dropped it down to 750-ish.  I'm on pretty much the same setup as you.  Ubuntu 11.04 x64 with 11.6/2.4 drivers/SDK, though I use phoenix directly with my own scripts.  I'm sure I could get more out of the 5970s, but I simply don't have time for that.

3 coins a day @ £2 each x7 = 63x4= £252 for 28 days mining. My electric bill is 100-110 a month. THats how i do my maths. Even 2 coins a day or a drop to £1.33($2.08 ill have you know) would give me £168 still leaving a profit.

Uhh, Zed doesn't think so. Neither does Google Spreadsheets.

Looks like closer to £58/month (28 days) at your £2.00/coin rate.

Are you using a Pentium with the FDIV bug for doing your math?

Just sayin'

His bug is far worse than than the FDIV bug, that one was was pretty obscure. m3sSh3aD's brain bug produces far more and far greater errors and in each and every attempt at math.

He posted earlier his electricity costs £0.16 per KwH. to get to £110/month means £0.15/H. So he would be mining at barely over 1000W
Hes mining mostly on heavily overclocked and overvolted 69x0 cards.
To get 3 BTC per day, you need ~3.5GH. @1000W?

Show me a GPU mining rig that gets anywhere near 3.5MH/W.

I think you could do it with some serious underclocking and undervolting on the right hardware.   Maybe....

If I ever get bored I may try to see what is the highest MH/W possible using one of my 3x5970 rigs.  I think I could make 3.5MH/W.

Sounds like a fun challenge.

I didn't think 6970s could hit 395 MH/s out of the box, unless they (Tomshardware) did some tweaking to theirs just to make it benchmark slightly above a 5870.

Total BS in that article. Most of my 5870s can EASILY get a maximum of 440 Mhash/s when slightly overclocked to 960 MHz.

6XXX sucks compared to 5XXX. Even a 6990 sucks compared to the 5970 king ATM. A 6970 can almost never beat a 5870. 

Nobody really knows how the 7XXX will perform or behave until some months after release to allow for optimizations and OCing.



What BS is the crap coming from your mouth.

Run your card at stock then come here and eat your own BS.

Is that the one where if you input "@[=g3,8d]\&fbb=-q]/hk%fg" (quote included) and press Delete, you get sucked into the internet?

Nice challenge. Hope you can find the time one day and show us if it is possible !

No, I think that is is the one where you get a visit from the Men In Black, or maybe the Man With One Red Shoe? I can never remember.

The FDIV bug is the one that allowed banks to honestly claim there was error in their spreadsheets. I know, "honest bank" sounds odd.  Smiley

It is amusing how threads can deteriorate. But this is +1 for sure!
