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

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!

Really? Would not believe until I tested it..

Thanks, that's amazing news! 8) I would never have seen it if it had been squirreled away in the Alt coin section.


Nvidia stock to the moon!  ;)

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.

AMD tends to have a significant price/performance advantage in the entry-mid range (<$300), while Nvidia tends to have a significant price/performance advantage in the higher range (>$300). They've had these niches carved out forever, so depending on what you generally spend, you'll probably end up with a bias -- that's my theory, anyway. It's fairly easy to check by looking at popular cards. A 270x is significantly less expensive and more powerful than a GTX 660, while a 290 is significantly less powerful and more expensive than a GTX 780.

The wattage is nice but Frys is selling the 750 for $160+tax.  I could get a 7870 for that price.

AMD's drivers really do blow chunks, though.  The amount of ballsing about to get them mining.

On a nVidia machine, just run cudaminer and it's hashing.  No SDK voodoo, no dodgy driver versions. 

Definitely thinking of getting a couple of 750Ti to replace my clapped out old 7770 and 7850 cards.

Flawed article in every way.

This is a low end card, which doesn't put out much khash. A high end card will cost what 780s used to cost and that is 700+. Power requirement for those cards is slightly less than AMD but cost signifanctly more.

Plus by the time Maxwell is out, which is a long way out, AMD will have a new architecture

Actually quite impressed with the hash / watt.

That being said....I am not gonna pay +~$150 or more for a card that doesn't even break 300khs.

Will be interesting to keep an eye on the new Maxwell high end iterations.

However much you save on electricity, you will lose several times over in infrastructural costs. You will need more cards to get the same speed, meaning bigger and/or more motherboards in your miner.
Additionally, overclocking the 750 is a big no-no. PCIe power draw is capped at 75W, while this card draws 68W already. So unless you get an auxiliary power connector for every card on your miner, get ready for the lovely smell of well-done PCB. Even if you supply the 750s with the right environment, they are still budget cards and will not survive as long under a reasonable overclock.

Methinks the author of the article has never dealt with building a miner himself and all that impresses him is the hash-to-watt ratio.

I agree with Wirel though, a high-end Maxwell GPU might be well worth considering. A bit like what AMD did with the HD 6*** generation - slightly slower, but much more power efficient than the HD 5***.

Exactly!!! In order to get the same speeds as say a 280x, you will need 3 times as many cards. Its already an issue getting more than 4 cards to work properly. You will need more motherboards, more memory, more risers, etc...

People writing these articles are looking in one direction. Yes it saves money on power, but the rest of the expenses will far outweigh that benefit.

Not worth to mine with Nvidia

Yeah, as a gamer I rather have Nvidia and it's drivers, but the voodoo and immaturity has to do with AMD coming later to GPGPU and sooner to mining. On recent drivers you don't need SDK

one 7950 230Euros Avg 600Khs, 1 GTX 750 150Euros Avg 280Khs so i dont think Nvidia is cheap but yes you have to pay les electricity bill but more investment=more MB,HDD,Memory etc

So:

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

How is that better? I dont get it.

Anyone in this thread actually running more than a few cards?

I am currently trying to run 22x amd 280x cards. The basement where these are running is now almost 30 degree Celsius. And I'm hashing SHA3 which creates a fraction of the heat scrypt does. Not to mention the amount of power all of this draws. with the 280x's i have a watt to hash ratio of 2,6. So my 5,8kw is roughly giving me 15mh/s on scrypt where as with nvidia rigs (that by the way is cheaper to build) with equal power usage i could get 28mh/s. Anyone who dont see the math why the profit margin is very much in favour of nVidia needs to do a reality check. Because 45kw power a year is not exactly cheap.

This is a game changer (http://coinramble.com/?p=39)! stop being fanboys were in the profit business not fanboy business!

Valid points. Now factor in additional motherboards, processors, memory, hard drives, power supplies (because you can only hook up so many cards to each one), additional racks/space.

The build cost is equally cheaper.


Where i buy my components which is not nearly as cheap as many other country's i come up with a 1,91Kh/s per $ for  for a nVidia setup where as i get 2,1kh/s per $ for a AMD setup (all expenses included). heat = more space required or heavier cooling, these cards also run a lot colder than what AMD does as well as reports are that cards barely get upto 65 degree, and heat is something that is very hard on AMD as they easily run upto 90+++ unless you have a ton of fans and space between the cards.

Accusing others of being fanboys just because they are discussing, is also unwarranted. Take this rhetoric elsewhere please.

Did you undervolt your cards?

I did not intend to offend anyone, so I'm sorry if anyone felt offended by that.


But seriously, tables have turned. initial investment in $ per # is closely the same as building a AMD rig yet you can save 50% of the power, which in the long run is where your main expense lies.


(yes of-course i undervolt my cards, anything else would be insanity)

Oh indeed, on tables turning when considering hash/W, I can see that coming.

In the second half the year, ASICs will also be entering the market.

The problem with that is that nvidia is already more efficient using 28nm on maxwell.

I'm yet to see evidence of this

Evidence is in the OP. ???
GTX 750/Ti is a 28nm Maxwell card.

$35-40 to mine 200-210kh <---- used 5770s.  Every one of them I have (5) mine at 850+core/1200 RAM @ 1.000 volts.

These 2 reviews contradict themselves:

Also, look at https://bitcointalk.org/index.php?topic=395004

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

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.




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.

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.

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

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.

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?

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. :)

Edit:Pressed Save before finishing my post by mistake.

This simply isn't true.

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.

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?

I have written a overview where i calculate most common GFX cards used for mining as of now CoinRamble.com - GRAPHICS CARD COMPARISON OVERVIEW (http://coinramble.com/?p=101) i compare cards against each-other and some graphs to visualize it all.
