I'm still buying 7970's... if the official 7990 comes out, I'll buy that too and sell these 7970s...
Until ASICs are available for purchase in quantities... GPU mining for BTC (and especially LTC) is a viable option.

I looked at 7990s over 7970s last night, it doesn't make sense to me.
ROUGHLY same power consumption, ROUGHLY same max OC, same hashing power at same clocks.
But 2x7970s £560 and 7990 costs £730+ if you can find it. Even factoring in reductions in 'specialist' motherboard requirements for the equivalent of 4 cards, and case requirements, it doesn't come close to paying for itself.
Higher resale value? I just picked one up.. M |
I mine at Kano's Pool because it pays the best and is completely transparent! Come join me! |

Also another reason for 7990s is the increased density.
No you're not going to beat FPGA's and ASIC's on the power front, but these GPU's are way easier to obtain. And if you're electricity costs are low enough you can stay in the game with GPU's far longer than those who suffer the cost issues of running them.

Powercolor Devil 13 7990.
Link to Album with actual voltage measurements. http://imgur.com/a/kFqHC#2 The real voltage is 0.944 while afterburner shows 1.000 One question: Why? Unless I'm missing something, this has no place in mining. A year ago maybe, but not now. Bragging rights? Gaming? Had $1000 (or equiv) sitting around burning a hole in your (virtual) pocket? Think it's going to be a cold winter, needed an extra heat source? I'm sure it looks nice.. would I want one? No.. M Litecoin mining, for example |

So the e-peen contest has begun, if I glue 3x7970 together will you buy that for $2000 as well? (premium goes up per card ofc)

How are you getting higher density? Are you going to run more than 3 of them in 1 rig? are you going to run them in a rack? If not then get 6x7950/7970s and have the same density. The only density that matters is mh/rig, mh/card is irrelevant. For every 7990 you buy you could have had 3.5-4x7950s depending on at what price you can find them, how does it make any sense to pick the 7990. Even counting the extra motherboard requirements etc you would still be looking at 3x7950 vs 1x7990 price wise. Justify that please, all I get when I have asked is "it's my money and I can do what I want" |

I think it should be noted that this Devil 13 is a 3 slot 7990, the newest 7990s are 2 slot and they OC and cool better.
this Devil 13 is at 925mhz stock. (3 slots)
the new 7990 are 950mhz stock and oc to ~1100mhz @ 80C. (2 slots)

Are the Malta's any different with mining / Power ?

my malta does 375w for the card, 1100-1250mh/s 576mh/s per gpu @ 1000mhz per gpu (stock speed) so thats 1152 mh/s running stock speed. Pretty efficient on power usage. |
