280x almost all out of stock at newegg

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.

You know NV market gk104 based and dual gk104 Teslas for the specific purpose of high sp integer HPC work (oil discovery simulations, mapping)? Thats why its expensive even-though it is poor in "real" HPC work...

Point is, HPC work all differ in their demands. But NV have that market due to a massive head start (good leadership) and wide usage of CUDA.

 

[ShintaiDK]

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

I fully agree. That train left without nVidia with AMD waving back from the departing train.

But on the other hand, its just a matter of time as well before scrypt gets hit by ASIC/FPGA.

So I dont blame they either for still keeping their eyes shut. Its understandable.

ASICs can only be used for bitcoin. Existing ASICs do not work for litecoin, which is part of their draw and why the difficulty hasn't been increasing quite as much as it has for bitcoin. Some are said to be in the works, but by the time ASICs happen for litecoin the smart miners will move to another crypto currency. That's how it's been working - only the not so smart guys stay with the older cryptos.

And this is why pretty much the 7970s are sold out everywhere. It's the best option for LTC. If and when LTC ASICs come to fruition, the people who (as mentioned) aren't morons will simply move to another crypto currency...That said, I do think LTC will become more and more difficult precisely because everyone and their brother are trying to mine with radeons now. That definitely will NOT have good effects on longevity....it won't get as bad as bitcoin, but I think it will get bad...

Well if LTC shoots up to BTC prices, I will be the last one to complain. Because by the time ASICs come to LTC I will have enough LTC in my wallet to cash out and still be left with a hefty profit.

But yeah, 280x is basically a slightly beefed up 7950 and 7950 was and still is the best bang for the buck for mining, so that's why they are all sold out everywhere.

Hopefully there will be more coming back in stock for cybermonday

I don't think LTC will be like bitcoin. There are rumors of LTC ASICs but...they're far away for the time being, so the difficulty will go up but it wont' go up to bitcoin levels. GPU mining for bitcoins is basically impossible now, whereas LTC is still more or less profitable even if the difficulty rises.

Like I said though...even if worse comes to worse, people will move on to the next crypto currency.

"The 1 MH/s unit is called Isis. Expected weight of the unit is around 7 kilograms, with dimensions of 48.5cm x 24cm x 9 cm. A gold rated Power Supply is included in the purchase, and power consumption should be around 150W."

http://majesti.co/cryptonerd/crypto-industries-announces-three-scrypt-fgpa-miners/

Looks like a next gen 20nm GPU will match that kind of output.

These are the ones more likely to be not vaporware, whereas others promise amazing BS of 500 kHa/s at 20W, unlikely, due to scrypts loving fast vram with low latency. GDDR5 itself, a few GB wouldn't even fit in that power envelope.

I dont see GPUs being obsolete for scrypt mining anytime soon.

 

[BallaTheFeared]

I think Scrypt will prove very (already has really) resilient to ASICs.

I doubt LTC will ever reach BTC prices for various reasons, unless BTC suddenly becomes undesirable.

 

[Silverforce11]

As long as you can freely and quickly exchange other coins into BTC, then eventually the market will decide which coin is the most desirable (it doesn't have to be BTC, as BTC -> altcoin exchange happen easily), and it will depend on 3 factors: 1) speed of transaction, 2) security & anonymity and 3) fame from news reports, blogs etc, something big pushing it.

 

[n0x1ous]

So thats probably all she wrote for the 7970's and 7950's after they were cleaned out this weekend. 280x clearly better bang for the buck than r9 290?

I was able to snag another reference 7970 Saturday but Im trying to think ahead......

 

[Sohaltang]

Someone just offered me 500$ for my pair of 7950's. Sure hope payment arrives soon. Guess Ill be buying a 290x or a 780ti soon

Reference 7900 is actually very very good for mining, because the cooler is capable of keeping it cool including the VRM at only ~45% fanspeed. At those speeds, it not loud, and they go in cases nice due to exhausting hot air outside.

I had a 7970 early this year mining BTC, its half the noise as the R290.

yeah I've always been a sucker for reference cards. subconsciously I feel like they have better resale (not sure if true) and I think they are nicer looking than open air coolers. Plus If I ever get around to experimenting with a custom loop.....

What the hell is a sp integer?

 

[OCGuy]

Why would anyone mine with a 280x over a 7970 if they have the option.....

One etailer's stock on a card that has been around is not enough data to make a educated guess of either supply or demand

 

[Silverforce11]

Relating to your comment.. and why even gk104 which has a "poor" GPGPU architecture due to gimped DP makes a good Tesla product.

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

What is "REAL" GPGPU?

Is it not "REAL" if there's a massive server farm of Radeons to perform distributed computing en-mass and get heaps of $$?

Find me this magical Single Precision Integer please. It doesn't mean what you think it means.

 

[RussianSensation]

Because it's essentially the same thing and they cost roughly the same. 7970 is now OOS everywhere too so your option is 280X or spending more on R9 290s.

"Another difference favoring Bitcoin mining on AMD GPUs instead of Nvidia's is that 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, but requires three separate hardware instructions to be emulated on Nvidia GPUs (2 shifts + 1 add). This alone gives AMD another 1.7x performance advantage (~1900 instructions instead of ~3250 to execute the SHA-256 compression function)." ~ Source

What is "REAL" GPGPU?

General-Purpose Computation on Graphics Processing Unit. Bitcoins and Litecoins fit that description.

You guys can keep using your magical Single Precision Integers. Your universe obviously having imprecise integers. I'll continue using my Integers that are exact.

Huh? No one said anything about magical integers, except you. AMD's architecture is currently superior for SHA-256 32-bit integer calculations much quicker than NV's. This is one of the major reasons why AMD's cards are superior for scrypt/bitcoin hashing. It's really your loss if you don't want to utilize your cards for free $ and that you don't believe AMD's architecture is superior for SHA-256 calculations vs. NV's. This is no different than when in the past NV's cards ran Folding@Home faster. Different GPGPU tasks run faster depending on the specific GPU architecture.

You know exactly what he means, 32bit integer. what does one even call a 64bit integer in a standardized way? ( long can be 32 or 64 depending, long long etc)

Ah ok.....looks like a mining run.....I remember the last one extremely well.

I hope today's LTC miners get to experience what those of us doing BTC in 2011 have. Someday it would be cool to hear some stories about how AMD cards changed ATer's lives.......I know my 5850s and later a 7970.....along with some help in the BTC thread (especially Slowspyder) ended up being a positive force for me personally.

32 bit integer computation is made only when the result of the computation yield a number whose magnitude is inferior or equal to 2.(2^32 ) - 1 wich is the upper limit of a number expressed in a 2 radix with 32 bits, hence the result will be totaly accurate since no rounding is done like in FP computations, so much for your belief that the results wouldnt be precise wich is some like of wishfull thought to not aknowledge that you perhaps did the wrong choice when buying a card for HPC purposes , or where
you joking.???...

As already pointed we know what he means , after all double precision FP has not double but orders of magnitude higher precision than what is called simple precision so any of us can use a faulty language with no consequences
unless one is lacking not in reading but in contextual comprehension...

Keep using your Single Precision Integers in your universe where Integers are imprecise then.
