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.

e.g

and a real world scenario:

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.
Could you present your calculations?

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.

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...

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?

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.

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.

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

2.Retire the PC,buy ultra cheap NUC style PC off eBay (frees up my Mac for filmmaking work.NUC will host ASICs with hub) and buy up a lot of DualMiners as the noise/heat/power use is a big problem where I am.Other people don't like the noisy computer so ASIC is the option.

I'd also like to add that 60W for 242 or 280Kh/s as I once saw with a moderate overclock is quite impressive meaning that 2 cards will give me around 484Kh/s to 560Kh/s for only 120W total while my HD6950 gives me 484Kh/s and uses 220W+ which is amazing how things have developed so quickly from Nvidia. Smiley

Buy one of these, awesome machine and performance, about €280 new, http://www.asus.com/EeeBox_PCs/EB1036/#specifications
Or one of these with SO-DIMM DDR3 + HDD/SSD, even better, http://www.asrock.com/ipc/overview.asp?Model=IMB-150


Well, my €140 7970 gives me 620-630 KH/s on just 180-190 Watts, underclocked.

750Ti is a budget and low-power card and it is already at 285 khash. That's because of the new Maxwell architecture used in the card. Imagine the higher end cards NVIDIA will release with Maxwell and where the mining power can go. AMD is back to the drawing board again.

Why would AMD be going back to the drawing board? Are they specifically designing their graphics cards to target miners?

No-one buys AMD GPUs for gaming - really, mining is the only reason anyone would buy an AMD card.  nVidia's cards and drivers are better than AMD's, always have been.

Now that the mining niche is gone, there's really no good reason to buy AMD.

This simply isn't true.

Just stumbled upon this article. 60 watts - 242kh/s. No power connectors required.

http://www.forbes.com/sites/jasonevangelho/2014/02/20/nvidia-is-about-to-steal-the-cryptocurrency-mining-crown-from-amd/

I see now the thread is in the wrong forum. If there is a moderator, I kindly request that you move it to the appropriate board. Thank you!
That's great news for me as I'm looking to re tool my mining operation as my Radeon HD6950,as much as I love it for the impressive hash power (484Kh/s),it's showing it's age and developing issues (I think that running it 24/7 for 2 years has worn out the card due to wierd glitches showing up now-unexplained crashes,black screens when I try to overclock now,pink squares appearing) meaning that I need to replace that card soon.

I've got 2 options for improving mining operation (for contract selling):
1.Buy 2 of these cards plus new mobo/CPU/RAM (as current system doesn't support multiple GPUs as it lacks multi-GPU chips/capabilities-using a mobo from 2007 after other machine was sold off)
2.Retire the PC,buy ultra cheap NUC style PC off eBay (frees up my Mac for filmmaking work.NUC will host ASICs with hub) and buy up a lot of DualMiners as the noise/heat/power use is a big problem where I am.Other people don't like the noisy computer so ASIC is the option.

I'd also like to add that 60W for 242 or 280Kh/s as I once saw with a moderate overclock is quite impressive meaning that 2 cards will give me around 484Kh/s to 560Kh/s for only 120W total while my HD6950 gives me 484Kh/s and uses 220W+ which is amazing how things have developed so quickly from Nvidia.

How easily can you install cudaminer in litecoinBAMT? Or is it even do-able?
Or are there any linux-os's that work as good from usb-stick like BAMT?

So:

$150 to mine 245kh? <-- nVidia
$320 to mine 700kh? <-- AMD 280x

How is that better? I dont get it.

Actually, there have been speeds up to 340kh on the 750 Ti.
And without going to extremes easily breaking the 310 barrier.

It's not a huge difference at that point.

All these are still pretty preliminary either way until people have figured out how to get the most out of these cards like they have for AMD.

Any info about the hash-rate difference between 1Gb and 2Gb models?
1Gb is around 125€ and 2Gb is +150€

Hom much kh/s did it get? How it performes with sha-3 coin maining ?
Sounds like an awesome card, it is cheap to get PSU on that system, only expense more than regular rig would be raisers.

This 750 Ti came out now? 7970 came out what Dec 2011??! lol, you f**king kidding me?!? 3 years playing catch up and can't even beat it at price, or hash per sec?

Dream on.



are those 750ti cards already available, anyone can confirm that they are so good at mining? How about sha 3 mining, not scrypt ?

They are, for abour €130 each, but they have no PCI-E power connector or anything on the card, so you have to provide one if you want to have more than 1 or 2 on a motherboard.
