Nvidia more efficient to mine scrypt?

[waltermot321]

Anybody tried the new nvidia gpu?

I fail to see the advantages of these cards, no matter which way you slice it.

You need 3x the number of motherboards, memory, hard drives, power supplies and all other supplies to match 4x 280x cards. You need at least 11 of the 750ti cards to do so. 11x 60watt = 660 + 3 motherboards and other components (910w total if you want to be conservative).

VS.

1 motherboard and all other components + 4x 280x cards = WAY cheaper to put together, and draws 1125w of power BEFORE undervolting. Extra power draw is negligible.

PLEASE explain to me why anyone sane enough would bother with low end NVidia cards?

High end Nvidia Maxwell cards will be released during the second half of this way by which time scrypt ASICs will be starting to show up.

is realy 4x 280X cards uses only 1120W, seems not very realistic.
As my calculations show, these nvidia cards are 2x times more efficient thant amd curently.

Scrypt ASICs are already starting to show up: http://hashra.com/

we are not talking about setting up a rig with 750Ti. we are discussing the possibilities when high-eng cards with Maxwell architecture (the same that 750Ti uses) are released by NVIDIA, the advantage will be on NVIDIA side, because the cards will have hashing power same or greater than amd and will be much more power-efficient.

I'm actually seriously considering building a huge setup consisting of 750Ti's for me the profit margin is the price i pay for electricity, and im already pulling 6kw.


I read somewhere that cudaMiner has some trouble running on 1x -> 16x risers, are there any truth to this? (Im looking at 5x or 6x these cards in each of my rigs but before i actually buy a ton of these cards id love to hear from someone who either know or run multiple nVidia cards on risers)

I too would like an answer on this if anyone knows. Powered / non powered risers? Some 750 Ti cards have additional power supplies, so there are many variations on how you can set this up...

To get more than 2x 750 Ti on one motherboard, you will need powered risers since they draw all the power through the PCIe slot.

Gigabyte makes a 750 Ti with a 6 pin power adapter. No idea how much power it will draw from it vs the PCIe if connected.

Could you present your calculations?

[j0achim]

I have written a overview where i calculate most common GFX cards used for mining as of now CoinRamble.com - GRAPHICS CARD COMPARISON OVERVIEW i compare cards against each-other and some graphs to visualize it all.
