Nvidia more efficient to mine scrypt?

[j0achim]

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.

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! stop being fanboys were in the profit business not fanboy business!

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

Did you undervolt your cards?

[j0achim]

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.

The problem is that there are no high-end Maxwell cards, and there will not be any until later this year.

Nvidia will not build high-end Maxwell cards using the 28nm node, it will wait for TSMC’s 20nm high-performance node, which is almost ready, but not quite. It should be ready for full-scale production sometime in the second half of 2014.

However, by the time Nvidia launches high-end GM200 series products based on Maxwell, AMD will also transition to 20nm with a tweaked Hawaii architecture, so it shouldn’t have much trouble maintaining its lead in the GPU mining niche.

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.

[ewhenn]

So:

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

How is that better? I dont get it.

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

[InCoinsITrust]

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

[SolidStateSurvivor]

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.

[InCoinsITrust]

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.

[ANJULE]

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

[ghur]

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.

[ANJULE]

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?

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!

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.

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.

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.
