280x almost all out of stock at newegg

[OILFIELDTRASH]

Was there a major sale or something? Only a couple models left in stock. Anyone know what happened? Or are they just a hot item?

 

[ShintaiDK]

I assume you only checked newegg?

Could simply be allocation of Tahiti cards. I see plenty of them here in europe. Or maybe there was a black friday offer?

HD79xx is also sold out.

Appears to be out of stock at amazon as well.

Black Friday, Cyber Monday... and the LTC craze. So many new workers mining online in the past few days.

 

[Hauk]

Maybe that was AMD's strategy in releasing R9 290/X with current cooler. Sorry couldn't resist.

280x + good AIB designs = sales? It is a good offering..

Bingo! Mining LTC is on fire right now.

Sold out in many stores in Canada. NCIX one of the largest stores barely has any left:

Canada computers also shows very limited stock:

We have Mantle, R9 280X beating 770 in BF4, and NV has no videocard in the $300-350 space with 3GB of VRAM that can beat R9 280X. Many people refuse to buy a GPU for $300+ with only 2GB of VRAM if they intend to keep it for 2 years+. Then there is LTC mining, which allows this card to pay for itself in a very short amount of time, measured in months.

yeah i was surprised to see all R9 280X / HD 7970 / HD 7950 cards out of stock at newegg. looks like the crypto currency mining is at all time high because of record prices on the bitcoins / litecoins

hwc talks about this currency being accepted by colleges for tuition fees. i still can't believe it go so much acceptance

That explains the huge variance in stock vs country electric price

On the acceptance note, friend of mine got part of ASIC bitcoin mining setup. He just bought a plane tocket with bitcoins. I was shocked.

 

[Silverforce11]

Dudes buy boats, sports cars and even property with bitcoins.. you must really not have paid any attention relating to these currency for the past year.

I still have BTC I mined in Feb - May this year, when ASICs didnt spoil the fun, at current prices, its worth a few GTX 780ti.

Even now, a R290 pays for itself in about 3 weeks mining scrypt coins. All this talk of 780s vs R290s.. really, its a joke. There's no comparison, one is free after a short period of time, and over the long haul actually makes you a LOT of $$.

You must have been living under a rock for the last 4 years. We have been saying since HD4870 days that NV cards are not worth their time. There is a thread with 640,000 views on this topic. Back then a single 4870/90 made 1 bitcoin in 1 day, which if you held some from that day, is $1100+ today. Meaning if you held say 10 bitcoins from 4870 days, you'd have $11K.

It still depends on electricity prices. So dont generalize something that only accounts for some countries.

 

[Silverforce11]

Really, if you live in a cold climate, and you're not mining to generate coins AND heating, its a complete waste turning on your heater, which costs you a lot of $$ to run.

Setup an open top rig, 3-4 GPUs in there in a room, you just got yourself a nice heater that prints $$.

Even if you paid $1 USD per kWh, its still very profitable in the short term and per the trend for the past years, extremely profitable in the long term.

Central heating here still beats a miner setup. A miner setup would simply cost more, make noise and uneven heat, not to mention removing the ability of using it while it mines.

 

[Silverforce11]

Open top rig, open air twin/3 fan GPUs, all that warm air is pushed away warming the room quickly, no noisy due to the coolers. Central heating = you pay to use it. Mining heating = you EARN $ using it.

Electricity cost (minus coin value) > central heating cost.

So it heavily depends on your heating type and cost, your electricity price and the PC usage.

 

[Silverforce11]

What's your electricity cost? I know in Denmark its ridiculous, but plug in your numbers: dustcoin.com

7950, 600 kHa/s, 250W. Power cost $1 USD per kWh (extremely high), still makes over $200 profit a month, enough to pay for itself. After that, its a heater that makes you $$, rather than a heater that costs you $$. If you don't leave your PC on all the time, you can add idle power to that, another 50-70W. Still profitable.

It's true for many countries. It's true for Canada and US and most of Europe, unless you live in Hawaii. At current rates, it's probably true for almost every country I can think of. If you can afford to buy a $400 GPU, you can afford to mine at today's rates. Actually right now with LTC mining, the break-even period is way shorter than it ever was for 7970. The only thing stopping me right now from buying 10+ R9 290s is a physical wattage/amperage limit where I am at.

 

[ShintaiDK]

0.41USD.

Ok now I can see its changed.

http://www.ltc-charts.com/period-charts.php?period=1-month&resolution=day&pair=ltc-usd&market=btc-e

Last 2 weeks price exploded with 11x. Had it been before, then litecoin mining would be a loss in most of EU.

For EU energy prices:
http://energy.eu/

Before the price change, litecoin in Denmark would yield approx -40$ to -50$ a month. Assuming you would hold 250W or below.(180Kw/h per month.). To compare, 1Mw/h central heating cost just around 100$. 1Mw/h with litecoins (2 weeks ago) would have costed around 250$.

 

[Silverforce11]

I made the mistake of stop mining altogether, when ASICs ruined GPU mining BTC.. I didn't look into alt coins where its scrypt based. Even if prices fall in the immediate term, and your mining isn't profitable or barely break even, I would still keep on doing it, because history is on the side of those who possess a lot of coins and holding it for longer term.

 

[ShintaiDK]

Now I really understand, with that 11x increase, why Tahiti cards are sold out.

What is it about amd cards that make them so much better at mining? Is this expected to continue or will nvidia change something in future architecture to address this?

Integer FMA

That's it. I'm pretty sure the only reason Nvidia doesn't have it is because of back-room deals between them, since AMD has had it since 5xxx series, and Nvidia hasn't had it on anything.

Maybe Maxwell will have it. No clue.

Only useful when working on integers though, which really shouldn't be most of the real GPGPU work anyways.

The mining algorithm is based on SHA-256, which makes heavy use of the 32-bit integer right rotate operation. This operation can be implemented as a single hardware instruction on AMD GPUs (BIT_ALIGN_INT), but requires three separate hardware instructions to be emulated on Nvidia GPUs (2 shifts + 1 add).

I dont think nVidia sees the mining industry as big enough to implement it, just for that.

Its because the fail to see, my small mining pool has over 22,000 workers, thats a lot of Radeons.
