My point was AMD doesn't have a monopoly on microstutter issues.
Your post is hypocritical when NVIDIA has non-gaming heavy workloads for their CUDA based GPUs. Digital coin mining is not first workload that wants 24 hours/7 days operation e.g. Fold @ Home.
With NVIDIA dominating GpGPU in the past years, the main article is hypocritical i.e. one rule for NVIDIA and a different rule for AMD.
Nah, of course not. But after having had both SLi and Crossfire and doing many builds over many different platforms with each...posting those results here...what NVidia provides with multi-GPU is better for me and my dollar.
If I could actually get the R9 290 @ the MRSP, then that's what I would have bought.
NVidia dominating is purely based on marketing. AMD(ATI) has ALWAYS delivered better HARDWARE solutions for GPGPU, IMHO. They just suck in the software department.
From my perspective, really, AMD has always been the trend-setter in this market, and NVidia comes in after and capitalizes on what AMD provides.
No, the wavefront is larger than 64bit payload i.e. there's four SIMD payload within one wavefront. SIMD's FMA operand format is 3.
Is it purely based on marketing when NVIDIA has more GpGPU installations in HPC when compared to AMD GpGPU?
"DigiTimes estimates the move could increase AMD's share of the professional GPU market to 30%, taking away share from NVIDIA"
No with "AMD(ATI) has ALWAYS delivered better HARDWARE solutions for GPGPU" e.g. VLIW5 based Radeon HD is not suited for complex GpGPU workloads and there are reasons why AMD dumped VLIW5 and VLIW4 Radeon HD designs.
If you read http://wili.cc/blog/gpgpu-faceoff.html each GPU designs offers different advantages.
Notice "App 2" (Ambient Occlusion)'s integer arithmetics advantage component relates to AMD GCN's mining coin results.

Where are your sources? It's people like you that have made me stop supporting Nvidia. They have too loyalists that are completely clueless. Keep buying their overpriced products though.
And that's all I have to say about that.
The sad thing is bitcoining ruins the cards. So don't expect any useable cards on the second hand market. My second hand 7970 came from a miner and it isn't stable at stock speeds even (crashes idle and sometimes load) and I am warrantying it as a result . Really glad they honor second hand cards. The PO didn't tell me it was used for mining... I found that out later.
Every bitcoin miner plans to sell his gpu's when he is done with them and generally the idea is to keep them sellable. I know a lot of miners try to keep their gpu's below 80c. I myself aimed for no more than 75c. It does depend on each miner though.
How did you determine the damage was caused by mining rather than any other number of ways, even something as simple as being dropped in transit? Blaming damage on GPU mining seems like a convenient excuse to avoid analyzing a complicated problem with multiple potential causes. In addition, there are always fraudulent sellers passing off broken products as working; GPU mining doesn't change that.
Some might OC the VRAM a touch too hard though, since Scrypt-based hashing seems to benefit from VRAM overclocking (at least my card seems to benefit from that while running Feathercoin (which is a temporary experiment of mine that I will soon quit b/c of lack of profitability)).
Because its the only thing that makes sense. The card is physically damage free and looks brand new. No dust at all. Its really bendy though like the guy threw three of them in a case and didnt support them and they heated up and warped. He was selling 5 at the time as working. My 7850 is totally 100% stable. The 7970 destabilizes the system in seconds. I don't want to go into the long of it but I tested every component and multiple reformats and its the GPU. Its been sent to gigabyte, passed the stress test because their engineer didn't read my note about it crashing at idle if you let it sit. Now I have to send it back.
I am running stock bios and no overclock with latest drivers. Its the bitcoining. I saw the ebay seller had extensive litecoin feedback after I bought it. Blah. I tried bios flashing, even a 7970 ghz bios to see if it would raise the voltages for stability but no luck. The rev 2.1 locks it down so even adding volts is impossible to shore up the stock clock. I get artifacts at stock even. Temperatures don't even crack 65*C too.
Also I think its either the ram or the vrm because the memory won't tolerate even a 10mhz overclock (zero headroom isn't normal) in catalyst or it might be something to do with vrm not maintaining idle voltages?
I am not quite an expert in this, but it does sound to me that it is the VRM(s) on the card not powering it right. What voltage readings do Afterburner or GPU-Z report?
i want to get into litecoin but i cant find the knowledge lol
I gotta reinstall it to find out, might be awhile lol
I really wanted to get a pair of r9 290s with the sapphire tech or power color coolers but since the prices jumped I wound up getting a evga titan for 600 from eBay instead of selling my titan..
And now you get to run all games on stratosphere settings. That's a litecoin win bro.
So, I'll ask you. Do you know of any issues with Hawaii and Crossfire/Eyefinity? That's specifically what was being claimed. Most of us are aware of Tahiti's issues, but I've seen nothing that shows Hawaii has similar issues. Simply painting Hawaii with Tahiti's brush is being disingenuous.
As far as it being a driver issue, I'd say since Hawaii and Tahiti use the same drivers, it's likely a hardware problem that's had a Band-aid applied via drivers (Supposed to be out this month.).
Where are you getting this from? Documentation of any type, please.
Barely working? First time I see a card "barely works". It either does or is broken and does not, there's nothing inbetween.
Also first time I see a claim a card degrades over time by intense usage.
Theres plenty of times things barely work. Heres an example: the card is overclocked and tweaked to run bitcoin with maximum hash. Then the user bios flashes it back and sells it on ebay. It is now unstable even at stock settings and I have to underclock it to get it to work.
When I was younger I owned a lot of things that degraded really bad from heat. I had a Pentium4 inside of a 2004 Shuttle barebones mini pc that ran really hot (100*C) all the time because the heatpipes in the shuttle case would shift the thermal paste when the case was moved. This Pentium 4 never worked right after that on later full sized mobos. Heat ruins electronics. Remember the XBox RROD? Mining generates a lot of heat when you put 4 cards next to each other.
Here is a typical mining setup:
Now I know why my PCB sags so bad.
Heres an inhouse example:
LOL what the actual fuck?!
I can see what you mean, partially at least though.
Guess I assumed people with brains, which apparently applies in homeopatic number of cases only
Yeah theres a lot of people who don't have brains in it, thats why its such a bubble. I don't know how anyone could ever statistically model a futures price for bitcoin because its purely based on past price increases rather than anything else. Thats a bubble. "yeah man its gonna go up because its been going up, time to buy in!" It has a really high cost of carry (electricity bill) and it has inherent value only in that it allows pedo's and druggies to buy illegal stuff.
Anyway, it ruins cards. Try running furmark 24/7 for a year and see if your card works. Same deal.
As a gamer/hobbyist miner, IMO there is no reason to buy nvidia at this point. Why buy a nvidia card when I can run my radeons when I'm not gaming and essentially have my cards pay for themselves after only 1 or 2 months? I enjoyed nvidia products for very many years but I am not going to turn down what is essentially a top tier, free, crossfire setup. The litecoin difficulty rose as more and more AMD cards were added to the network but seems to have stabilized as the supply of cards dried up. Litecoin mining is still profitable assuming you pay a reasonably low rate for electricity. Besides, the money nowadays is not really in bitcoin or even litecoin anymore, but other scrypt based alt coins such as dogecoin/gridcoin where the profits are potentially enormous for the early miners.
I have been an avid nvidia follower for most of my gaming career but things have shifted with the litecoin craze. An HD 7950 that sold for <$200 last year now sells for 1.5x that, used. So a gamer who bought a 7950 or 7970 in the past year actually saw the value of their card RISE over time, something that I never could have imagined. In terms of performance, all of my AMD cards overclock extremely well, far better than anything I've been able to do with my nvidia cards. They also perform well for all the games I've tried and the drivers are not nearly as bad as people make them out to be.
